Sabulilitoribacter multivorans gen. nov., sp. nov., a polysaccharide-degrading bacterium of the family Flavobacteriaceae isolated from seashore sand

A Gram-negative, aerobic, non-flagellated, non-gliding and rod-shaped bacterial strain, designated M-M16^T, was isolated from seashore sand around a seaweed farm on the South Sea, South Korea, and its taxonomic position was investigated by using a polyphasic study. Strain M-M16^T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. Strain M-M16^T exhibited the highest 16S rRNA gene sequence similarity values to the type strains of Gaetbulibacter lutimaris (96.5 %) and Flaviramulus basaltis (95.8 %). Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain M-M16^T clustered with the type strains of Gaetbulibacter species and F. basaltis. Strain M-M16^T contained MK-6 as the predominant menaquinone and iso-C_15:1 G, iso-C_15:0 and iso-C_17:0 3-OH as the major fatty acids. The major polar lipids detected in strain M-M16^T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain M-M16^T was 37.4 mol%. The phylogenetic and chemotaxonomic data and other phenotypic properties revealed that strain M-M16^T represents a novel genus and species within the family Flavobacteriaceae, for which the name Sabulilitoribacter multivorans gen. nov., sp. nov. is proposed. The type strain of S. multivorans is M-M16^T (= KCTC 32326^T = CCUG 63831^T).

Complete genome sequence of Paenibacillus sp. strain JDR-2

Paenibacillus sp. strain JDR-2, an aggressively xylanolytic bacterium isolated from sweetgum (Liquidambar styraciflua) wood, is able to efficiently depolymerize, assimilate and metabolize 4-O-methylglucuronoxylan, the predominant structural component of hardwood hemicelluloses. A basis for this capability was first supported by the identification of genes and characterization of encoded enzymes and has been further defined by the sequencing and annotation of the complete genome, which we describe. In addition to genes implicated in the utilization of β-1,4-xylan, genes have also been identified for the utilization of other hemicellulosic polysaccharides. The genome of Paenibacillus sp. JDR-2 contains 7,184,930 bp in a single replicon with 6,288 protein-coding and 122 RNA genes. Uniquely prominent are 874 genes encoding proteins involved in carbohydrate transport and metabolism. The prevalence and organization of these genes support a metabolic potential for bioprocessing of hemicellulose fractions derived from lignocellulosic resources.

We report on genome sequencing of Oligotropha carboxidovorans strain OM4 and resequencing of strain OM5. The genomes of both are composed of one chromosome and two plasmids. The presence of two plasmids in the OM5 genome is inconsistent with the previously published sequence, for which only one plasmid was described (D. Paul, S. Bridges, S. Burgess, Y. Dandass, and M. Lawrence, BMC Genomics 11:511, 2010).

Metabolism of 2-, 3- and 4-hydroxybenzoates by soil isolates Alcaligenes sp. strain PPH and Pseudomonas sp. strain PPD

Pseudomonas sp. strain PPD and Alcaligenes sp. strain PPH isolated from soil by enrichment culture technique utilize 2-, 3- and 4-hydroxybenzoates as the sole source of carbon and energy. The degradation pathways were elucidated by performing whole-cell O(2) uptake, enzyme activity and induction studies. Depending on the mixture of carbon source and the preculture condition, strain PPH was found to degrade 2-hydroxybenzoate either via the catechol or gentisate route and has both salicylate 1-hydroxylase and salicylate 5-hydroxylase. Strain PPD utilizes 2-hydroxybenzoate via gentisate. Both strains degrade 3- and 4-hydroxybenzoate via gentisate and protocatechuate, respectively. Enzymes were induced by respective hydroxybenzoate. Growth pattern, O(2) uptake and enzyme activity profiles on the mixture of three hydroxybenzoates as a carbon source suggest coutilization by both strains. When 3- or 4-hydroxybenzoate grown culture was used as an inoculum, strain PPH failed to utilize 2-hydroxybenzoate via catechol, indicating the modulation of the metabolic pathways, thus generating metabolic diversity.     

Complete genome sequence of an aerobic thermoacidophilic crenarchaeon, Sulfolobus tokodaii strain7.

The complete genomic sequence of an aerobic thermoacidophilic crenarchaeon, Sulfolobus tokodaii strain7 which optimally grows at 80 degrees C, at low pH, and under aerobic conditions, has been determined by the whole genome shotgun method with slight modifications. The genomic size was 2,694,756 bp long and the G + C content was 32.8%. The following RNA-coding genes were identified: a single 16S-23S rRNA cluster, one 5S rRNA gene and 46 tRNA genes (including 24 intron-containing tRNA genes). The repetitive sequences identified were SR-type repetitive sequences, long dispersed-type repetitive sequences and Tn-like repetitive elements. The genome contained 2826 potential protein-coding regions (open reading frames, ORFs). By similarity search against public databases, 911 (32.2%) ORFs were related to functional assigned genes, 921 (32.6%) were related to conserved ORFs of unknown function, 145 (5.1%) contained some motifs, and remaining 849 (30.0%) did not show any significant similarity to the registered sequences. The ORFs with functional assignments included the candidate genes involved in sulfide metabolism, the TCA cycle and the respiratory chain. Sequence comparison provided evidence suggesting the integration of plasmid, rearrangement of genomic structure, and duplication of genomic regions that may be responsible for the larger genomic size of the S. tokodaii strain7 genome. The genome contained eukaryote-type genes which were not identified in other archaea and lacked the CCA sequence in the tRNA genes. The result suggests that this strain is closer to eukaryotes among the archaea strains so far sequenced. The data presented in this paper are also available on the internet homepage (http://www.bio.nite.go.jp/E-home/genome_list-e.html/).     

Complete genome of the mutualistic, N2-fixing grass endophyte Azoarcus sp. strain BH72

Azoarcus sp. strain BH72, a mutualistic endophyte of rice and other grasses, is of agrobiotechnological interest because it supplies biologically fixed nitrogen to its host and colonizes plants in remarkably high numbers without eliciting disease symptoms. The complete genome sequence is 4,376,040-bp long and contains 3,992 predicted protein-coding sequences. Genome comparison with the Azoarcus-related soil bacterium strain EbN1 revealed a surprisingly low degree of synteny. Coding sequences involved in the synthesis of surface components potentially important for plant-microbe interactions were more closely related to those of plant-associated bacteria. Strain BH72 appears to be 'disarmed' compared to plant pathogens, having only a few enzymes that degrade plant cell walls; it lacks type III and IV secretion systems, related toxins and an N-acyl homoserine lactones-based communication system. The genome contains remarkably few mobile elements, indicating a low rate of recent gene transfer that is presumably due to adaptation to a stable, low-stress microenvironment.     

Complete genome sequence of Pusillimonas sp. T7-7, a cold-tolerant diesel oil-degrading bacterium isolated from the Bohai Sea in China

Pusillimonas sp. T7-7 is a diesel oil-degrading cold-tolerant bacterium isolated from the benthal mud of a petroleum-contaminated site in Bohai Sea, China.

Genome analysis revealed many features of typical marine bacteria, including the absence of intact sugar metabolic pathways, the presence of glyoxylate and gluconeogenesis pathways, and the abilities for nitrate assimilation and denitrification, as well as sulfate reduction and sulfite oxidation. The presence of novel genes for the degradation of diesel oils was suggested.
