A review of the genera <Emphasis Type="Italic">Calotelea,Calliscelio</Emphasis>, and <Emphasis Type="Italic">Oxyscelio</Emphasis> (Scelioninae,Scelionidae, Proctotrupoidea) from the Palaearctic fauna

Nine new species of scelionids collected in Japan, Israel, and the Ukraine, Calotelea shimurai Kononova et Fursov, C. japonica Kononova, C. stellae Kononova, Calliscelio recens Kononova, C. floridum Kononova, C. parilis Kononova, C. ordo Kononova, Oxyscelio florum Kononova, and O. perpensum Kononova, are described. A brief morphological characteristics of the mentioned genera and some data on the geographical distribution of these species are given. Calotelea shimurai differs from C. striola Kononova in the sculpture of the metasoma (tergites I–III striate, whereas in C. striola striation present only on tergites I and II), fore-wing venation (stigmal vein of C. shimurai 0.43 times as long as postmarginal vein and 1.75 times as long as marginal one; in C. striola, stigmal vein 0.52 times as long as postmarginal vein and 1.3 times as long as marginal one), and the length of the metasoma (in C. shimurai and C. striola, metasoma 4.0 and 2.3 times as long as wide, respectively). Calotelea shimurai parasitizes in eggs of the dragonflies Aeshna nigroflava Martin, Planaeschna milnei Selys, and Boyeria macachlani (Aeshnidae, Odonata). C. japonica is closely related to C. originalis Kozlov and Kononova, but differs from it in the sculpture of the metasoma (metasomal tergites with longitudinal wrinkles against the bright smooth background; in C. originalis, tergites I and II with longitudinal wrinkles against the alveolate background), in the coloration of fore wing (infuscate in C. japonica and dark, with dark transverse stripes in C. originalis). C. stellae differs from C. artus Kozlov and Kononova in the more flattened mesoscutum (C. artus with protruding mesoscutum) and the sculpture of the metasomal tergites (in C. stellae, only petiolus and tergite II striate, while in C. artus, such striation present on tergites I–IV). C. stellae was reared from eggs of unidentified Orthoptera. C. recens is closely related to C. parilis Kononova. It can be distinguished by the fore-wing venation (C. recens has stigmal vein, which is twice as long as marginal vein and 0.66 times as long as postmarginal one; stigmal vein of C. parilis is 3 times as long as marginal vein and 0.83 times as long as postmarginal one), by the sculpture of the metasoma, and coloration of the coxae (yellow in C. recens and black in C. parilis). C. floridum is similar to C. mediterranea Kieffer, but can be identified by the length of the postmarginal vein, which is 3 times as long as the stigmal vein, whereas C. mediterranea has the postmarginal vein, which is only twice as long as the stigmal one. C. floridum also differs in the sculpture of the metasoma (C. floridum has all the metasomal tergites with longitudinal lines, while C. mediterranea has only metasomal petiolus with the same sculpture and tergites II–IV with alveolate sculpture, tergites V and VI are slightly stippled) and in the coloration of the legs, which are yellow (as coxae), while C. mediterranea has brownish black legs. C. parilis resembles C. recens, but differs from it in the fore-wing venation, sculpture of the metasoma, and coloration of the coxae. C. ordo differs from the closely related C. ruficollis Kozlov et Kononova in the head sculpture, which is finely alveolate in C. ordo and finely granulate in C. ruficollis. Oxyscelio florum is closely related to O. perpensum, but differs from it in the coloration of the body and size of the antennal segments, stigmal and postmarginal veins, and metasomal tergites. O. perpensum is closely related to O. florum. The main distinguishing morphological characters are similar to those in O. florum. O. perpensum was reared from eggs of unidentified Orthoptera.     

Association of polymorphic markers of chemokine genes,their receptors,and <Emphasis Type="Italic">CD14</Emphasis> gene with coronary atherosclerosis

Atherosclerosis represents an inflammatory response to the disturbance of the endothelial layer in the arterial bloodstream. In the present study, an analysis of associations of polymorphic markers for the genes controlling synthesis of proteins involved in atherosclerosis pathogenesis in coronary atherosclerosis (CA) patients (217 subjects) and in a control group (250 subjects) was conducted. The following genes were examined: rs991804 (CCL2 gene), rs1126579 (CXCR2 gene), rs4074 (CXCL1 gene), rs4073 (CXCL8 gene), rs333 (CCR5 gene), rs2471859 (CXCR4 gene), rs1801157 (CXCL12 gene), and rs2569190 (CD14 gene). Using the Monte Carlo and Markov chain (APSampler) method, allele/genotype combinations associated with both low and high CA risk were revealed. The most important findings included the following: CXCR4*T/T + CCL2*C + CCR5*I/I (P_perm = 1 × 10^–6, OR = 0.44, 95% CI 0.3–0.63), CXCR2*C + CD14*C + CXCL12*G + CCL2*C + CCR5*D (P_perm = 4 × 10^–6, OR = 5.78, 95% CI 2.34–14.28), CD14*C + CCL2*C/C + CCR5*D (P_perm = 6.3 × 10^–6, OR = 5.81, 95% CI 2.17–15.56), CXCL8*A + CXCR2*C + CD14*T + CXCR4*C (P_perm = 0.01, OR = 3.21, 95% CI 1.63–6.31).     

An overlooked hybrid between the two diploid <Emphasis Type="Italic">Chenopodium</Emphasis> species in Central Europe determined by microsatellite and morphological analysis

The presence and extent of hybridization within the Chenopodium album aggregate (Amaranthaceae) is still unclear. Although many hybrid combinations have been described, their existence in the field has never been systematically studied and verified. The main aim of this study was to ascertain the extent of interspecific hybridization between the diploid species C. ficifolium and C. suecicum using highly variable nuclear microsatellite markers. Due to the absence of such kind of molecular markers for the whole C. album group, we divided the analysis into two steps: (1) Eleven microsatellite loci designed for the closely related species C. quinoa were cross-amplified in five Eurasian species of the C. album diploid–polyploid complex, i.e. C. album s.s. (6x), C. striatiforme (4x), C. strictum (4x), C. ficifolium (2x) and C. suecicum (2x); (2) For the detection of interspecific hybridization between C. ficifolium and C. suecicum, we sampled 480 individuals from five localities in Central Europe. We also investigated morphological differences between the parental taxa and their hybrid and devised a key for their determination. Analysis of variation in microsatellite loci using Bayesian methods, PCoA and Neighbour-joining tree identified 32 F1 hybrids. These F1 hybrids, described here as C. paradoxum Mandák, formed a cluster between well-differentiated parental species, combining the morphological characters of both their parents. Moreover, genetic analyses also recognized several F2 or backcross hybrids, whose delimitation, mainly from C. suecicum and F1 hybrids, based on morphological characters, is problematic.     

Seven new species of <Emphasis Type="Italic">Ceratomyxa</Emphasis> Thélohan, 1892 (Myxozoa) from the gall-bladders of serranid fishes from the Great Barrier Reef,Australia

Ceratomyxa spp. from the gall-bladder of five members of the family Serranidae were examined for their taxonomic identity. This paper describes seven new ceratomyxid species, i.e. C. brayi n. sp. and C. whippsi n. sp from Cephalopholis boenak (Bloch); C. cutmorei n. sp. from Epinephelus fasciatus (Forsskål); C. gleesoni n. sp. from Plectropomus leopardus (Lacépède); C. hooperi n. sp. and C. nolani n. sp. from E. quoyanus (Valenciennes); and C. yokoyamai n. sp. from E. maculatus (Bloch). Each species is characterised morphologically and small subunit (SSU) rDNA sequences. All seven new species have so far been found in only a single host species.     

Characterization of bacterial composition and diversity in a long-term petroleum contaminated soil and isolation of high-efficiency alkane-degrading strains using an improved medium

Bacterial community and diversity in a long-term petroleum-contaminated soil of an oilfield were characterized using 16S rRNA gene-based Illumina MiSeq high-throughput sequencing. Results indicated that Proteobacteria (49.11%) and Actinobacteria (24.24%) were the most dominant phyla, and the most abundant genera were Pseudoxanthomonas (8.47%), Luteimonas (3.64%), Alkanindiges (9.76%), Acinetobacter (5.26%) and Agromyces (8.56%) in the soil. Meanwhile a series of cultivations were carried out for isolation of alkane degraders from petroleum-contaminated soil with gellan gum and agar as gelling agents. And the isolates were classified by their 16S rRNA genes. Nine of the isolates including Enterobacter, Pseudomonas,Acinetobacter, Rhizobium, Bacillus, Sphingomonas, Paenibacillus, Variovorax and Rhodococcus showed strong biodegradability of alkane mixture (C9–C30) in a wide range of chain-length, which could be potentially applied in enhancement of bioremediation.     

New data on the taxonomy of ground-beetles (Coleoptera,Carabidae) from Palaearctic Asia

Synonymy of two genus-group names is substantiated: Tricholicinus Poppius, 1912 (type species: Tricholicinus setosus J.R. Sahlberg, 1880) = Martyr Semenov et Znojko, 1929 (type species: Martyr praeteritorum Semenov et Znojko, 1929), syn. n. and Psammodromius Peyerimhoff, 1927 (type species: Psammodromius noctivagus Peyerimhoff, 1927) = Xanthomelina Iablokoff-Khnzorian, 1964 (type species: Apristus zajtzewi Eichler, 1924), syn. n. Synonymy of the following names of the species-group taxa is established: Calosoma (Callisthenes) elegans (Kirsch, 1859) = C. (Callisthenes) declive (Dohrn, 1884), syn. n., lectotype of the latter is designated; Carabus (Semnocarabus) erosus erosus Motschulsky, 1866 = C. (Semnocarabus) erosus karascharensis (Eidam, 1931), syn. n., lectotype of the latter is designated; C. (Semnocarabus) cicatricosulus pseudoerosus Mandl, 1955 = C. (Semnocarabus) bogdanowi semnocosulus Deuve et Tian, 2013, syn. n.; Chlaenius (Dinodes) viridis (Ménétriés, 1832) = Ch. pallidicornis Ballion, 1871, syn. n.; Licinus (Tricholicinus) setosus (J.R. Sahlberg, 1880) = Licinus mongolicus Reitter, 1900, syn. n. = Martyr praeteritorum Semenov et Znojko, 1929, syn. n. = Martyr alter Semenov et Znojko, 1929, syn. n.; Psammodromius zajtzewi (Eichler, 1924), comb. n. (transferred from the genus Xanthomelina Iablokoff-Khnzorian, 1964) = Psammodromius pallidicolor (Mandl, 1973), syn. n. = Psammodromius damanabii Morvan, 1977, syn. n.Calosoma (Callisthenes) rostislavi Semenov, 1906, stat. resurr. is resurrected from synonyms of C. (Callisthenes) declive (Dohrn, 1884).     

Expression analysis on mycoparasitism related genes during antagonism of <Emphasis Type="Italic">Trichoderma</Emphasis> with <Emphasis Type="Italic">Colletotrichum falcatum</Emphasis> causing red rot in sugarcane

Present study was aimed to select a suitable Trichoderma isolate as candidate antagonist based on its efficacy in producing cell wall degrading enzymes (CWDEs), its mycoparasitism activity and expression of related genes against the red rot pathogen caused by Colletotrichum falcatum in sugarcane. For which, six different isolates of Trichoderma selected from our earlier studies (T. harzianum, T. asperullum) were evaluated based on their capability in releasing cell wall degrading enzymes individually and during antagonism with C. falcatum in dual plate. Amongst T. harzianum (T20) exhibited the greatest mycoparasitic potential against the C. falcatum, by producing higher concentration of  CWDEs viz., chitinase and β-1, 3-glucanase, slightly lower amounts of cellulase and protease with significant reduction in polygalacturonase produced by pathogen. Further microscopic observation on interaction of C. falcatum with the selected isolate of T. harzianum (T20) exhibited the mycoparasitic activity of antagonist over pathogen in dual culture and inhibition of C. falcatum pathogenesis in detached sugarcane leaves. In addition, expression pattern of eight genes coding various enzymes involved in mycoparasitism by T. harzianum over C. falcatum were analyzed using qRT-PCR in vitro and on sugarcane leaves. In in vitro interactions, five genes of  cell wall degrading enzymes viz., chitinase (chit33), endochitinase (endo42), β-1, 3-glucanase (glu), exochitinase 1 (exc1), exochitinase 2 (exc2), were upregulated during and after contact as compared to before contact, while three genes related with proteases such as alkaline proteinase (prb1), trypsin-like protease (Pra1), subtilin-like serine protease (ssp), genes were upregulated during the contact with C. falcatum and slightly down regulated after contact. In detached leaves, seven genes were potentially upregulated except subtilin-like serine protease, which was down regulated during interaction of C. falcatum and T. harzianum as compared to T. harzianum inoculation alone. All these biochemical and molecular results confirm the efficacy of T. harzianum (T20) against C. falcatum and justify the right selection of candidate antagonist for our further studies on identification of antifungal genes/proteins against C. falcatum in sugarcane.     

A search for microscopic fungi with directed hydroxylase activity for the synthesis of steroid drugs

The hydroxylase activities of new strains such as Curvularia lunata, C. geniculata, C. eragrostidis, C. prasadii, Ulocladium botrytis, Alternaria tenuis, and Fusarium oxysporum toward three steroid substrates, namely, androstenedione (AD), cortexolone (S), and dehydroepiandrosterone acetate (DAA), were characterized. The 9α-hydroxylase activity of C. lunata 1011 cells against S to form 9α-hydroxy-S was shown for the first time. It was found that C. geniculata 837 and F. oxysporum 11dn1 strains can hydroxylate substrates to form pharmacologically promising 7α-hydroxysteroids. C. geniculata 837 cells selectively hydroxylate AD, resulting in 7α-hydroxytestosterone, whereas F. oxysporum 11dn1 leads to the transformation of DAA to 7α-hydroxydehydroepiandrosterone.     

In Vitro Susceptibility of a Large Collection of <Emphasis Type="Italic">Candida</Emphasis> Strains Against Fluconazole and Voriconazole by Using the CLSI Disk Diffusion Assay

We evaluated all Candida spp. isolates obtained from patients admitted to two tertiary care hospitals between 1999 and 2003 in the city of São Paulo, Brazil. The in vitro activities of fluconazole (FCZ) and voriconazole were determined by the agar disk diffusion test using the Clinical and Laboratory Standards Institute M44-A guidelines. The inhibition zone diameters were read and interpreted automatically by the BIOMIC^® image-analysis plate reader system. We tested a total of 4,625 strains, including 2,393 strains of C. albicans (51.7%), 658 of C. tropicalis (14.2%), 503 of C. glabrata (10.9%), 495 of C. parapsilosis (10.7%), 292 of C. rugosa (6.3%), 195 of C. guilliermondii (4.2%) and 89 of other Candida species (2.0%). Only 2.0% of the strains tested were classified as dose-dependent susceptible (DDS), and 5.8% of them were resistant to FCZ. The resistance or DDS to fluconazole was verified mainly among C. glabrata (7.8%), C. krusei (67.9%) and C. rugosa (65.1%). Voriconazole exhibited better activity in vitro than fluconazole, even in isolates fluconazole resistant. The resistance of fluconazole and voriconazole did not increase in the isolates of Candida spp. during the evaluated period.     

Characterization of an ene-reductase from <Emphasis Type="Italic">Meyerozyma guilliermondii</Emphasis> for asymmetric bioreduction of α,β-unsaturated compounds

Objectives

To characterize a novel ene-reductase from Meyerozyma guilliermondii and achieve the ene-reductase-mediated reduction of activated C=C bonds.

Results

The gene encoding an ene-reductase was cloned from M. guilliermondii. Sequence homology analysis showed that MgER shared the maximal amino acid sequence identity of 57 % with OYE2.6 from Scheffersomyces stipitis. MgER showed the highest specific activity at 30 °C and pH 7 (100 mM sodium phosphate buffer), and excellent stereoselectivities were achieved for the reduction of (R)-carvone and ketoisophorone. Under the reaction conditions (30 °C and pH 7.0), 150 mM (R)-carvone could be completely converted to (2R,5R)-dihydrocarvone within 22 h employing purified MgER as catalyst, resulting in a yield of 98.9 % and an optical purity of >99 % d.e.

Conclusion

MgER was characterized as a novel ene-reductase from yeast and showed great potential for the asymmetric reduction of activated C=C bonds of α,β-unsaturated compounds.

     

Clinical and Microbiological Investigation of Fungemia from Four Hospitals in China

In this study, fungemia cases from four tertiary hospitals located in Shanghai and Anhui province in China from March 2012 to December 2013 were enrolled to investigate clinical features, species distribution, antifungal susceptibility and strain relatedness. During the study period, 137 non-duplicate cases and their corresponding isolates were collected. Six different genera of fungi were identified, of which Candida spp. were the most common (126/137, 91.97 %), with C. albicans predominating (48/137, 35.03 %). The non-Candida fungi rate reached 8.03 % (11/137), and Pichia spp. was the most common (5/137, 3.65 %). Compared with C. albicans, non-C. albicans fungi-associated fungemia was more likely in younger (p = 0.004) and male patients (χ ² = 6.2618, p = 0.0123) and patients from ICUs (χ ² = 6.3783, p = 0.0116). Overall, the susceptible/WT rates of common Candida spp. to fluconazole, itraconazole, voriconazole, flucytosine, amphotericin B and caspofungin were 74.63, 92.31, 93.16, 96.58, 100 and 95.69 %, respectively. C. tropicalis and C. guilliermondii had a low susceptibility to fluconazole: 79.95 and 77.78 %, respectively. No isolates were resistant/WT to caspofungin, but C. parapsilosis and C. guilliermondii had high MIC₉₀ values; 1 and 2 mg/L, respectively. In terms of genotyping, MLST was taken for C. glabrata and C. tropicalis, while microsatellite marker analysis was used for C. albicans and C. parapsilosis. C. glabrata was predominantly clone ST7, accounting for 75 %, while the other isolates showed genetic diversity. Considering the increased proportion of non-C. albicans fungi and the presence of endemic clones of C. glabrata, it is essential to undertake additional surveillance of fungemia.     

<Emphasis Type="Italic">Condyloderes kurilensis</Emphasis> sp. nov. (Kinorhyncha: Cyclorhagida)—a new deep water species from the abyssal plain near the Kuril-Kamchatka Trench

A new species of centroderid kinorhynchs, Condyloderes kurilensis sp. nov., collected from muddy sediment at the abyssal plain near the Kuril-Kamchatka Trench, North-West Pacific, is described and illustrated using light and electron microscopy. Previously, members of the genus Condyloderes were found only in nearly shallow water enviroments—C. multispinosus (North Sea), C. paradoxus (Bengal Bay), C. setoensis (Tanabe Bay, Japan), C. storchi (Argentina coast), and C. megastigma (Korea Strait). The new species is characterized by the presence of lateroventral cuspidate spines only on trunk segment 8 in both sexes, paired ventromedial appendages (tubules) on trunk segments 7 and 8 in females only, and dorsolateral spines on trunk segment 10 in males only. Condyloderes kurilensis sp. nov. constitutes the sixth species of the genus Condyloderes described so far and the only second abyssal species of the Kinorhyncha described from the North-West Pacific. A key to the six species of the genus Condyloderes is proposed.     

A review of the subgenus <Emphasis Type="Italic">Carpelimus</Emphasis> s. str. (Coleoptera,Staphylinidae) from tropical Africa

A review of the subgenus Carpelimus (s. str.) from tropical Africa is given. The subgenus includes 10 species. A new species C. uhligi sp. n. is described, neotype of Trogophloeus insularis, Kraatz 1858 is designated. T. aequithorax Bernhauer, 1932 is placed in synonymy with C. dieganus (Fauvel, 1904); T. oculatus Wollaston, 1865 and T. meridioafricanus Scheerpeltz, 1974, with C. insularis (Kraatz, 1858), T. rudebecki Scheerpeltz, 1974 with C. memnonius (Erichson, 1840); T. yemenicus Coiffait, 1981 with C. niloticus (Erichson, 1840); T. nigerrimus Coiffait, 1935 and T. mimus Cameron, 1945, with C. rufitarsis (Fauvel, 1907); and T. bredoi Bernhauer, 1943, with C. transmarinus (Fauvel, 1907). Lectotypes of T. aequithorax, T. calidus, T. nigerrimus, and T. bredoi are designated. Twenty species are transferred from the genus Carpelimus, and the following new combinations are formed: Thinodromus brincki Scheerpeltz, 1972; Th. montiumdraconis Scheerpeltz, 1974; Th. rhodesianus Scheerpeltz, 1974; and Th. sudanensis Scheerpeltz, 1974 comb. nn.). The initial generic placement of Carpelimus luzidus Cameron, 1944 is restored.     

Phylogenetic reconstructions in the genus <Emphasis Type="Italic">Capra</Emphasis> (Bovidae,Artiodactyla) based on the mitochondrial DNA analysis

Mitochondrial genome fragments were examined in all species of the genus Capra (Bovidae, Artiodactyla). Phylogenetic analysis was carried out using 59 cytochrome b gene sequences (392 bp), and 22 sequences of the mtDNA variable fragment (402 bp). In the control region, two unique deletions were revealed. One of the deletions was found only in Capra cylindricornis (17 bp), while another one grouped C. caucasica with C. aegagrus (1 bp). The group of Caucasian wild goats splits into two clades, and furthermore, the sequences of C. caucasica demonstrate remarkable similarity to the sequences of C. aegagrus, while C. cylindricornis seems to have evolved independently for a long period of time. It was demonstrated that C. pyrenaica and C. ibex were extremely close to one another. Capra sibirica formed an outer group relative to the other species, and according to our data, was the most ancient species of the genus. On the contrary, genetic distance separating C. falconeri (the most independent species of the genus related to its morphology) from the other species is small.     

Multilocus phylogeny of <Emphasis Type="Italic">Clonostachys</Emphasis> subgenus <Emphasis Type="Italic">Bionectria</Emphasis> from Brazil and description of <Emphasis Type="Italic">Clonostachys chloroleuca</Emphasis> sp. nov.

Phylogenetic analyses based on protein-encoding gene exons and introns of ATP citrate lyase (ACL1), beta tubulin (TUB), the largest subunit of RNA polymerase II (RPB1), and translation elongation factor 1-α (TEF1) are used for inferring the existence of a new Clonostachys species from the Cerrado biome in Brazil, described here as C. chloroleuca. The species produces dimorphic, primary, and secondary conidiophores that form consistently greenish conidial masses on artificial media. It resembles therefore C. rosea f. catenulata although it differs from this species by less adpressed branches in the secondary conidiophores. The new species is also phylogenetically related to C. byssicola and C. rhizophaga. Our inventory suggests that C. byssicola, C. chloroleuca, C. pseudochroleuca, C. rhizophaga, C. rogersoniana, and C. rosea commonly occur in native and agriculturally used soils of the Cerrado and Amazon Forest. Using sequences available from two genome-sequenced strains employed as biological control agents, we confirm the identity of the European strain IK726 as C. rosea and identify strain 67-1 from China as C. chloroleuca.     

<Emphasis Type="Italic">Cacopsylla biwa</Emphasis> sp. nov. (Hemiptera: Psyllidae): a new pest of loquat <Emphasis Type="Italic">Eriobotrya japonica</Emphasis> (Rosaceae) in Japan

A new psyllid species, Cacopsylla biwa Inoue, sp. nov., is described from Tokushima Prefecture, Shikoku, Japan. This new species develops only on Eriobotrya japonica (Thunb.) Lindl. (Rosaceae), causing severe damage to its fruits and flowers. It is strongly suspected that C. biwa is an alien species. Morphological similarities and host-plant relationships indicate that C. biwa is most closely related to Cacopsylla eriobotryae (Yang) comb. nov. (transferred from Edentatipsylla Li), which occurs in Taiwan and feeds on Eriobotrya deflexa (Hemsl.) Nakai. Morphological diagnostic characteristics of C. biwa and differences from the other congeners are discussed. Information is provided on the biology and life cycle of the new species.     

Deep sequencing analysis of bacterial community structure of Soldhar hot spring,India

We investigated the bacterial community structure of Soldhar hot spring with extreme high temperature 95°C located in Uttarakhand, India using high throughput sequencing. Bacterial phyla Proteobacteria (88.8%), Deinococcus-Thermus (7.5%), Actinobacteria (2.3%), and Firmicutes (1.07%) were predominated in the sequencing survey, whereas Bacteroidetes, Verrucomicrobia, Aquificae and Acidobacteria were detected in relatively lower abundance in Soldhar hot spring. At the family level, Comamonadaceae (52.5%), Alteromonadaceae (15.9%), and Thermaceae (7.5%) were mostly dominated in the ecosystem followed by Chromatiaceae, Microbacteriaceae, and Cyclobacteriaceae. Besides, members of Rhodobacteraceae, Moraxellaceae, Xanthomonadaceae, Aquificaceae, Enterobacteriaceae, Bacillaceae, Methylophilaceae, etc. were detected as a relatively lower abundance. In the present study we discuss the overall microbial community structure and their relevance to the ecology of the Soldhar hot spring environment.     

New data on the fauna and systematics of Palaearctic species of the click-beetle subfamily Agrypninae Candèze, 1857 (Coleoptera,Elateridae)

New data on the distribution and taxonomy of some Palaearctic species of click-beetles of the subfamily Agrypninae are given. The external morphology and genitalia of the previously unknown females of Compsolacon korotjaevi Gur. and C. agrestis (Vats et Kash.) comb. n. are described. Several taxa are recorded from the following territories for the first time: the genus Eumoeus Cand. from the Palaearctic Region, the species Compsolacon agrestis comb. n. and C. himalayanus Jag. from Afghanistan, Compsolacon turkestanicus (Schw.) from Kyrgyzstan and Afghanistan, Danosoma conspersum (Gyll.) from Kazakhstan, Lacon quadrinodatus Lew. from Russia, and L. unicolor (Cand.) from Iraq. Several Northern Indian species of Agrypnus Esch. are transferred to Compsolacon Rtt., and their systematic positions are briefly discussed: C. agrestis, C. inlustris (Vats et Kash.), C. jacksoni (Vats et Kash.), C. kuluensis (Vats et Kash.), C. maisus (Vats et Kash.), C. planocorpus (Vats et Kash.), C. rameshi (Vats et Kash.), C. repercussus (Vats et Kash.), C. solanensis (Vats et Kash.), C. souslapisus (Vats et Kash.), C. subargillus (Vats et Kash.), C. subfaenum (Vats et Kash.) and C. sublapideus (Vats et Kash.) (all comb. n.). The following new combinations are also established: Compsolacon aequalis (Cand.) comb. n. and Compsolacon brachychaetus (Kollar) comb. n. (both ex Lacon). The following new synonymies are established: Lacon funebris (Sols.) = Adelocera grisea Schw., syn. n.; = Adelocera incompta Kr., syn. n.; Eumoeus murrayi Cand. = Tetralobus quadrifoveatus Vats et Kash., syn. n.     

Characteristic of Polysaccharide Complexes from <Emphasis Type="Italic">Centaurea scabiosa</Emphasis> L. and <Emphasis Type="Italic">Centaurea pseudomaculosa</Emphasis> Dobrocz.

We characterized polysaccharide complexes from Centaurea scabiosa L. and Centaurea pseudomaculosа Dobrocz. We proposed the technique of sequential selection of water-soluble polysaccharides and pectin substances from the aerial parts of studied objects. We have discovered that the content of water-soluble polysaccharides in the aerial parts of C. scabiosa was 2.8 times higher (2.7 ± 0.3%, n = 3) than in C. pseudomaculosа (0.97 ± 0.50%, n = 3). The content of pectin substances in the aerial parts of C. scabiosa was 2 times higher (7.6 ± 0.4%, n = 3) than in C. pseudomaculosа (3.9 ± 0.3%, n = 3). The residues of D-galacturonic acid, L-rhamnose, D-xylose, D-mannose, D-glucose, and D-galactose are the monomeric units of polysaccharide complexes from C. scabiosa and C. pseudomaculosa. Using ion-exchange chromatography, three polysaccharide fractions (molecular weights 667, 722, and 1027 kDa), whose monomer units are D-galacturonic acid, L-rhamnose, D-galactose, D-xylose, and D-glucose were isolated from the water-soluble polysaccharides of C. scabiosa.
