A Gram stain-negative, yellowish green-pigmented, facultatively anaerobic, motile, curved rod-shaped bacterium designated as strain JJ016T was isolated from an artificial lake in South Korea, and characterized using a polyphasic approach. The 16S rRNA gene sequence of strain JJ016T indicated that the isolate belonged to the family Rhodocyclaceae and exhibited 95.0% identity to Uliginosibacterium gangwonense 5YN10-9T. The major cellular fatty acids of the novel strain were summed feature 3 (C16:1 ω6c and/or C16:1 ω7c), C16:0, C14:0, and summed feature 8 (C18:1 ω7c and/or C18:1 ω6c). The DNA G+C content of strain JJ016T was 61.9 mol%. The major respiratory quinone and major polar lipid of strain JJ016T were ubiquinone-8 and phosphatidylethanolamine, respectively. Based on the morphological and physiological properties and the biochemical evidence presented, we concluded that strain JJ016T represents a novel species of a new genus in the family Rhodocyclaceae, for which the name Viridibacterium curvum gen. nov., sp. nov. is proposed. The type strain is JJ016T (=KACC 16899T =JCM 18715T). 相似文献

A novel, Gram-positive bacterium, designated DLS-06T, was isolated from scoria (volcanic ash) under rock on the peak of small mountain (300 m above the sea level; known as Darangshi
Oreum) in Jeju, Republic of Korea. The cells of the isolate were aerobic, oxidase-negative, catalase-positive, endospore-forming,
non-motile rods. The organism grew at 25∼30°C and initial pH 6.1∼9.1. A neighbour-joining tree based on 16S rRNA gene sequences
showed that the organism was related to members of the family “Sporolactobacillaceae” and related taxa. The phylogenetic neighbours were Pullulanibacillus naganoensis (95.2% 16S rRNA gene sequence similarity), Tuberibacillus calidus (95.0%) and Sporolactobacillus (91.8∼94.2%). Levels of 16S rRNA gene sequence similarity of the isolate to representatives of other genera were in the range
of 87.2∼93.7%. The organism contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan.
The predominant menaquinone was MK-7. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, an unknown
ninhydrin-positive phospholipid, three unknown phospholipids and an unknown lipid. The major fatty acids were anteiso-C15:0 and anteiso-C17:0. The G+C content of the DNA was 50.8 mol%. On the basis of the phenotypic and phylogenetic data presented in this study,
this organism represents a novel genus and species in the order Bacillales, for which the name Scopulibacillus darangshiensis gen. nov., sp. nov. is proposed. The type strain is DLS-06T (=DSM 19377T =KCTC 13161T). 相似文献

An aerobic, Gram-stain negative, rod-shaped, non-motile bacterium, designated as strain HQA918T, was isolated from an ascidian, Botryllus schlosseri, which was collected from the coast of Weihai in the north of the Yellow Sea, in China. The strain grew optimally at 28–30 °C, at pH values 7.0–8.0, and in the presence of 1.0–3.0% (w/v) sodium chloride (NaCl). A phylogenetic analysis based on 16S rRNA gene sequences showed that strain HQA918T can be affiliated with the family Flavobacteriaceae in the phylum Bacteroidetes, with 92.7% similarity to its close relatives. The major fatty acids identified were iso-C15:0, iso-C15:0 3-OH, and summed feature 3 (iso-C15:0 2-OH and/or C16:1ω7c). The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, and five unidentified polar lipids. The G+C content of the genomic DNA was 44.1 mol%. On the basis of the phylogenetic, genotypic, phenotypic, and chemotaxonomic data, this organism should be classified as a representative of a novel genus, for which the name Ascidiaceibacter gen. nov. is proposed. The type species is Ascidiaceibacter salegens sp. nov. (type strain HQA918T?=?KCTC 52719T?=?MCCC 1K03259T). 相似文献

A Gram-stain negative, facultative anaerobic, non-motile, strongly orange-pigmented and rod-shaped bacterium, designated XAY3209T, was isolated from a marine sediment sample collected from the coast of Weihai, China. Strain XAY3209T was found to grow optimally at 30 °C, at pH 7.0 and in the presence of 2.0% (w/v) NaCl. Its genomic DNA G+C content was 41.9 mol%. On the basis of 16S rRNA gene sequence similarity, the novel isolate belongs to the family Cyclobacteriaceae and is related to the genus Algoriphagus. It shares 98.1% 16S rRNA sequence identity with Algoriphagus marincola, its close phylogenetic relative, but did not show similarities more than 97% with other members of the genus Algoriphagus with validly published names. It contained menaquinone-7 (MK-7) as the sole respiratory quinone, iso-C15:0, iso-C17:1 ω9c and Summed feature 3 (C16:1 ω7c and/or iso-C15:0 2-OH) as the major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and five unidentified lipids. Results of physiological experiments, biochemical tests and genome average nucleotide identity value (with A. marincola MCCC 1F01203T) indicate that strain XAY3209T is genetically and phenotypically distinct from the species of the genus Algoriphagus with validly published names. Strain XAY3209T therefore represents a novel species, for which the name Algoriphagus formosus sp. nov. is proposed. The type strain is XAY3209T (= KCTC 52842T = MCCC 1H00189T). 相似文献

A strictly aerobic, Gram-stain negative, long rod-shaped, motile by gliding and yellow pigmented bacterium, designated strain w01T, was isolated from marine sediment. The strain was characterised to determine its taxonomic position by using a polyphasic approach. Strain w01T was observed to grow optimally in the presence of 3.0% (w/v) NaCl, at 30 °C and to hydrolyse Tweens 20, 40 and 80, starch, casein and alginate. Carotenoid pigments were found to be produced but not flexirubin-type pigments. On the basis of 16S rRNA gene sequence similarities, strain w01T is phylogenetically affiliated with the genus Aquimarina and is closely related to Aquimarina macrocephali JCM 15542T (97.4% sequence similarity) and Aquimarina muelleri KCTC 12285T (97.0%). Lower sequence similarities (<?97.0%) were found with the other currently recognised members of the genus Aquimarina. The predominant fatty acids were identified as iso-C15:0 (33.7%), C18:0 3-OH (16.8%) and C17:1ω7c (10.6%). The polar lipid profile was found to contain phosphatidylethanolamine, an unidentified aminolipid and two unidentified polar lipids. MK-6 was identified as the sole respiratory quinone. The G?+?C content of the genomic DNA was determined to be 33.3 mol%. Strain w01T can be differentiated genotypically and phenotypically from recognised species of the genus Aquimarina. The isolate is therefore concluded to represent a novel species, for which the name Aquimarina sediminis sp. nov. is proposed, with the type strain w01T (=?KCTC 62350T?=?MCCC 1H00287T). 相似文献

A novel Gram-negative and rod-shaped bacterium, designated N8T, was isolated from tidal flat sediment. Phylogenetic analysis based on 16S rRNA gene sequences showed that N8T strain is associated with the family Phyllobacteriaceae: two uncultured clones (98.4 and 99.8% 16S rRNA gene sequence similarity) and the genus Mesorhizobium (≤97.0%). The novel strain formed a separate clade with uncultured clones in the phylogenetic tree based on 16S rRNA gene
sequences. Cellular fatty acid profiles predominately comprised C18:1
ω7c and C19:0 cyclo ω8c. The major isoprenoid quinone is ubiquinone-10 and genomic DNA G+C content is 53.4 mol%. The polyphasic taxonomic study indicates
that the novel strain N8T represents a novel species of the new genus in the family Phyllobacteriaceae, named Aliihoeflea aestuarii. The type strain is N8T (= KCTC 22052T= JCM 15118T= DSM 19536T). 相似文献

A marine bacterium, designated IMCC3175T, was isolated from a seawater sample collected off the Antarctic coast. The strain was Gram-negative, obligately aerobic,
carotenoid pigment-containing, and rod-shaped bacterium that divided by binary fission. As determined by 16S rRNA gene sequence
comparisons, the most closely related genera were Formosa (92.9∼93.3%), Bizionia (91.6∼93.2%), Gaetbulibacter (91.5∼92.8%), Sediminibacter (92.7%), Yeosuana (92.6%), Subsaximicrobium (92.1∼92.2%), and Gillisia (89.5∼92.2%). Phylogenese analysis based on 16S rRNA gene sequences showed that the strain formed a monophyletic clade together
with the genera Sediminibacter and Subsaximicrobium but represented an independent phyletic line in this clade of the family Flavobacteriaceae. The DNA G+C content of the strain was 37.3 mol%. The major respiratory quinone was MK-6 and the predominant cellular fatty
acids were C16:1 ω7c and/or iso-C15:0 2-OH (12.8%), anteiso-C15:0 (9.4%), and iso-C16:1 (9.4%). Low 16S rRNA gene sequence similarity, formation of a distinct phylogenetic branch, and several phenotypic characteristics,
including a narrow range of temperature and salinity for growth, differentiated strain IMCC3175T from other related genera in the family Flavobacteriaceae. Therefore the name Antarcticimonas flava gen. nov., sp. nov. is proposed, with strain IMCC3175T (=KCCM 42713T =NBRC 103398T) as the type strain. 相似文献

Taxonomic studies were performed on three strains isolated from Cheonho reservoir in Cheonan, Korea. The isolates were Gram-negative,
aerobic, rod-shaped, non-motile, catalase-positive, and oxidase-positive. Colonies on solid media were cream-yellow, smooth,
shiny, and circular. Phylogenetic analysis of the 16S rRNA gene sequences revealed that these strains belong to the genus
Flavobacterium. The strains shared 98.6–99.4% sequence similarity with each other and showed less than 97% similarity with members of the
genus Flavobacterium with validly published names. The DNA-DNA hybridization results confirmed the separate genomic status of strains ARSA-42T, ARSA-103T, and ARSA-108T. The isolates contained menaqui-none-6 as the predominant menaquinone and iso-C15:0, iso-C15:0 3-OH, iso-Ci15:1 G, and iso-C16:0 3-OH as the major fatty acids. The genomic DNA G+C content of the isolates were 31.4–33.2 mol%. According to the phenotypic
and genotypic data, these organisms are classified as representative of three novel species in the genus Flavobacterium, and the name Flavobacterium koreense sp. nov. (strain ARSA-42T =KCTC 23182T =JCM 17066T =KACC 14969T), Flavobacterium chungnamense sp. nov. (strain ARSA-103T =KCTC 23183T =JCM 17068T =KACC 14971T), and Flavobacterium cheonanense sp. nov. (strain ARSA-108T =KCTC 23184T =JCM 17069T =KACC 14972) are proposed. 相似文献

WS-10T–a Gram-negative, non-motile, and aerobic bacterial strain–was isolated from the sediment of a shallow stream in Korea. The optimum ranges of temperature and pH for growth were 20–40°C (optimum 28°C) and pH 6.0–8.0 (optimum pH 7.0), respectively. The DNA G+C content of strain WS-10T was 72.7 mol%. The major fatty acids (>5%) were summed feature 8 (C18:1ω7c), summed feature 3 (C16:1ω7c and/or C16:1ω6c), C16:0, and C18:1 2-OH. The major polar lipids consisted of phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, and unidentified aminolipids. Q-10 was the predominant respiratory quinone. The highest similarities in the 16S rRNA gene sequence were shown with Paracraurococcus ruber (95.3%), Belnapia soli (95.3%), B. moabensis (95.1%), and B. rosea (95.0%). A phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that strain WS-10T formed a distinct line within a clade containing the genera Paracraurococcus, Craurococcus, and Belnapia in the family Acetobacteraceae. On the basis of polyphasic evidence, strain WS-10T represents a novel species of a new genus in the family Acetobacteraceae, for which the name Dankookia rubra gen. nov., sp. nov. is proposed. The type strain of the type species is WS-10T (= KACC 18533T = JCM 30602T). 相似文献

A novel bacterium B9T was isolated from tidal flat sediment. Its morphology, physiology, biochemical features, and 16S rRNA gene sequence were
characterized. Colonies of this strain are yellow and the cells are Gram-negative, rod-shaped, and do not require NaCl for
growth. The 16S rRNA gene sequence similarity indicated that strain B9T is associated with the genus Lysobacter (≤ 97.2%), Xanthomonas (≤ 96.8%), Pseudomonas (≤ 96.7%), and Luteimonas (≤ 96.0%). However, within the phylogenetic tree, this novel strain shares a branching point with the species Luteimonas composti CC-YY255T (96.0%). The DNA-DNA hybridization experiments showed a DNA-DNA homology of 23.0% between strain B9T and Luteimonas mephitis B1953/27.1T. The G+C content of genomic DNA of the type strain is 64.7 mol% (SD, 1.1). The predominant fatty acids are iso-C11:0, iso-C15:0, iso-C16:0, iso-C17:0, iso-C17:0
ω9c, and iso-C11:0 3-OH. Combined analysis of the 16S rRNA gene sequences, fatty acid profile, and results from physiological and biochemical
tests indicated that there is genotypic and phenotypic differentiation of the isolate from other Luteimonas species. For these reasons, strain B9T was proposed as a novel species, named Luteimonas aestuarii. The type strain of the new species is B9T (= KCTC 22048T, DSM 19680T). 相似文献

A Gram-stain-positive, aerobic, non-motile, non-spore-forming, and rod-shaped bacterium, designated strain CHu64-6-1T, was isolated from a 67-cm-long sediment core collected from the Daechung Reservoir at a water depth of 17-m in Daejeon, Republic of Korea. Comparative 16S rRNA gene sequence studies placed the new isolate in the class Sphingobacteriia, and the isolate is notably most closely related to Flavihumibacter sediminis CJ663T (98.1% similarity), Flavihumibacter solisilvae 3-3T (97.8%), Flavihumibacter petaseus T41T (97.5%), Flavihumibacter cheonanensis WS16T (97.4%), and Flavihumibacter stibioxidans YS-17T (97.2%). The cells of strain CHu64-6-1T formed yellow colonies on R2A agar and contained MK-7 as the only menaquinone, phosphatidylethanolamine, an unidentified phospholipid, and two unidentified aminolipids as the major polar lipids, and C15:0 iso, C17:0 iso 3-OH, C15:1 iso G, and C16:1ω5c as the major fatty acids (> 5%). The DNA G + C content of the genome was determined to be 46.5 mol%. The DNA-DNA hybridization values of strain CHu64-6-1T with F. sediminis CJ663T, F. solisilvae 3-3T, F. petaseus T41T, F. cheonanensis WS16T, and F. stibioxidans YS-17T were 12.4–33.2%. Based on the combined genotypic and phenotypic data, we propose that strain CHu64-6-1T represents a novel species of the genus Flavihumibacter, for which the name Flavihumibacter profundi sp. nov. is proposed. The type strain is CHu64-6-1T (= KCTC 62290T = CCTCC AB 2018060T). 相似文献

Kretzschmaria varians, a species apparently related to K. micropus, is described as new. It is distinguished primarily by having asci with 2 to 8 ascospores with inconstant germination slit
length and remains of synnemata on stromata and surrounding substrate. Xylaria coremiifera, described here as new, bears small fragile coremia on pulvinate stromata and the surrounding substrate. Asci often have
fewer than 8 ascospores, most frequently 4. Xylaria umbonata, described here as new, produces perithecia around a central umbo that appears to be the remains of a synnema. Ascospores
have long spiralling germination slits. 相似文献

The alphaproteobacterial strain JLT2003T was isolated from surface seawater off the coast of Guishan island, Taiwan. The strain was Gram negative, ovoid or coccoid,
non-motile and formed pink colonies on marine agar 2216 (MA; DIFCO) medium. The dominant fatty acids were C18:1ω7c, cyclo C19:0ω8c, and C16:0. The polar lipid profile consisted of diphosphatidylglycerol and phosphatidylglycerol. The major respiratory ubiquinone was
Q-10. The DNA G+C content was 62.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was
most closely related to Pontibaca methylaminivorans GRP21T with 94.8% similarity. The isolate was distinguishable from members of the family Rhodobacteraceae based on phenotypic and biochemical characteristics. On the basis of the taxonomic data presented, strain JLT2003T is considered to represent a novel species of a new genus, for which the name Oceaniovalibus guishaninsula gen. nov., sp. nov. is proposed. The type strain of Oceaniovalibus guishaninsula is JLT2003T (=JCM 17765T = CGMCC 1.10827T). 相似文献

A Gram-stain negative, ovoid or short rod-shaped, aerobic and non-motile bacterial strain, designated J82T, was isolated from a seawater sample collected from the coast of Yellow Sea in Qingdao, China. The strain grew at salinities of 1.0–6.0% (w/v) NaCl (optimum, 2.5%). Growth occurred at pH 6.0-8.0 (optimum, pH 7.0) and 10–42 °C (optimum, 28–30 °C). The genomic DNA G + C content was determined to be 57.5 mol%. Q-10 was detected as the respiratory quinone. The major fatty acid (>10%) was Summed feature 8 (C18:1 ω7c and/or C18:1 ω6c). The polar lipids consisted of phosphatidylethanolamine, two unidentified aminolipids and two unidentified polar lipids. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain J82T forms a distinct evolutionary lineage within the family Rhodobacteraceae. On the basis of phenotypic, chemotaxonomic and phylogenetic characteristics, the strain merits recognition as representative of a novel genus and species within the family Rhodobacteraceae for which the name Rubricella aquisinus gen. nov., sp. nov. is proposed. The type strain of Rubricella aquisinus is J82T (= DSM 103377T = CCTCC AB 2016170T). 相似文献

A novel strain, DCY108T was isolated from soil of a Panax ginseng field, Yeoncheon province (38°04′N 126°57′E), Republic of Korea. Strain DCY108T is Gram-negative, non-motile, non-flagellate, rod-shaped, and aerobic. The bacterium grows optimally at 25–30 °C, pH 6.5–7.0 and 1 % NaCl. Phylogenetically, strain DCY108T is closely related to Pedobacter jejuensis JCM 18824T, Pedobacter aquatilis JCM 13454T, Pedobacter kyungheensis LMG 26577T and the type strain of the genus Pedobacter heparinus DSM 2366T. The DNA–DNA relatedness values between strain DCY108T and its close phylogenetic neighbors were below 30.0 %. The DNA G+C content of strain DCY108T was determined to be 45.1 mol%. The predominant quinone was menaquinone 7 (MK-7). The major polar lipids were identified as phosphatidylethanolamine and three unidentified aminolipids AL1, AL13 and AL17. Iso-C15:00, iso-C17:03OH and summed feature 3 (C16:1 ω7c/C16:1 ω6c) were identified as the major fatty acids present in strain DCY108T. The results of physiological and biochemical tests allowed strain DCY108T to be differentiated phenotypically from other recognized species belonging to the genus Pedobacter. Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Pedobacter panacis sp. nov is proposed with the type strain designated as DCY108T (=CCTCCAB 2015196T = KCTC 42748T). 相似文献

A novel Gram-positive, oval-shaped, non-motile bacterium designated strain 16F1LT was isolated from sediment collected from the Han River in Seoul, Republic of Korea. Based on the 16S rRNA gene sequence (1,448 bp), this strain was identified as a member of the genus Deinococcus that belongs to the class Deinococci. Similarities in the 16S rRNA gene sequence were shown with Deinococcus daejeonensis MJ27T (99.0%), D. grandis DSM 3963T (98.1%), D. radiotolerans C1T (97.5%), and D. caeni Ho-08T (97.2%). Strain 16F1LT was classified as a different genomic species from closely related Deinococcus members, based on less than 70% DNA-DNA relatedness. Genomic DNA G+C content of strain 16F1LT was 67.2 mol%. Strain 16F1LT was found to grow at temperatures of 10–37°C (optimum 25°C) and pH 7–8 (optimum pH 7) on R2A medium, and was catalase-positive and oxidase-negative. Strain 16F1LT showed resistance to gamma radiation (D10 > 2 kGy). In addition, this strain had the following chemotaxonomic characteristics: the major fatty acids were C15:1ω6c and C16:1ω7c; the polar lipid profile contained phosphoglycolipids, unknown aminophospholipids, an unknown aminoglycolipid, unknown aminolipids, an unknown glycolipid, an unknown phospholipid, and an unknown polar lipid; the major quinone was MK-8. Phylogenetic, genotypic, phenotypic, and chemotaxonomic characteristics indicated that strain 16F1LT represents a novel species within the genus Deinococcus, for which the name Deinococcus sedimenti sp. nov. is proposed. The type strain is 16F1LT (=KCTC 33796T =JCM 31405T). 相似文献

Three psychrotrophic Arthrobacter strains, isolated from Antarctic lake sediment (An24, An25T) and deep-sea sediment (ZX6) were studied. Their 16S rRNA gene sequences showed highest similarities (97.0–97.9%) with those of A. nicotianae and A. protophormiae. All three strains underwent rod–coccus morphological change, had high mol% G+C content, were aerobic to slightly anaerobic, and grew between 0°C and 30°C, with optimal growth temperature around 25°C. The cell wall peptidoglycan was A4 variant. DNA–DNA hybridization, physiological and chemotaxonomic studies indicated that these three strains constituted a new homogeneous genomic species within the genus Arthrobacter, for which the name Arthrobacter ardleyensis, with the type strain An25T (CGMCC 1.3685, JCM 12921) was proposed.M.

A non-motile, pink-pigmented bacterial strain designated IMCC25679T, was isolated from freshwater Lake Chungju of Korea. Phylogenetic trees based on 16S rRNA gene sequences showed that the strain IMCC25679T formed a lineage within the genus Pedobacter. The strain IMCC25679T was closely related to Pedobacter daechungensis Dae 13T (96.4% sequence similarity), Pedobacter rivuli HME8457T (95.3%) and Pedobacter lentus DS-40T (94.3%). The major fatty acids of IMCC- 25679T were iso-C15:0, iso-C16:0 and summed feature 3 (comprising C16:1ω6c and/or C16:1ω7c). The major respiratory quinone was MK-7. The major polar lipids were phosphatidylethanolamine (PE), an unidentified sphingolipid (SL), an unidentified aminolipid (AL) and three unidentified polar lipids (PL). The DNA G + C content of IMCC25679T was 32.2 mol%. Based on the evidence presented in this study, the strain IMCC25679T represents a novel species within the genus Pedobacter, with the proposed name Pedobacter aquicola, sp. nov.

A Gram-negative, motile, aerobic and rod-shaped bacterial strain designated 119BY6-57T was isolated from spongin. The taxonomic position of the novel isolate was confirmed using the polyphasic approach. Strain 119BY6-57T grew well at 25–30°C on marine agar. On the basis of 16S rRNA gene sequence similarity, strain 119BY6-57T belongs to the family Xanthomonadaceae and is related to Lysobacter aestuarii S2-CT (99.8% sequence similarity), L. maris KMU-14T (97.5%), and L. daejeonensis GH1-9T (97.3%). Lower sequence similarities (97.0%) were found with all of the other recognized members of the genus Lysobacter. The G + C content of the genomic DNA was 69.9 mol%. The major respiratory quinone was Q-8 and the major fatty acids were C16:0 iso, C15:0 iso, summed feature 9 (comprising C17:1 iso ω9c and/or C16:0 10-methyl), summed feature 3 (comprising C16:1ω7c and/or C16:1ω6c), and C11:0 iso 3-OH. The polar lipids were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, three unidentified phospholipids, and an unidentified polar lipid. DNADNA relatedness values between strain 119BY6-57T and its closest phylogenetically neighbors were below 48.0 ± 2.1%. Based on genotypic and phenotypic characteristics, it is concluded that strain 119BY6-57T is a new member within the genus Lysobacter, for which the name Lysobacter spongiae sp. nov. is proposed. The type strain is 119BY6-57T (= KACC 19276T = LMG 30077T). 相似文献

of the D1/D2 domain of the large subunit (LSU) rRNA gene and the phylogenetic analysis, the five strains were assigned to
be one novel Ogataea species and two novel Candida species. Three strains (LN12, LN14T and LN16) represent a single novel species of the genus Ogataea, for which the name Ogataea phyllophila sp. nov. is proposed. The type strain is LN14T (= BCC 42666T = NBRC 107780T = CBS 12095T). Strain LN15T was assigned to be Candida chumphonensis sp. nov. (type strain LN15T = BCC 42667T = NBRC 107781T = CBS 12096T). Strain LN17T represented another novel species of Candida that was named Candida mattranensis sp. nov. (type strain LN17T = BCC 42668T = NBRC 107782T = CBS 12097T). 相似文献
