Draft Genome Sequence of Paenisporosarcina sp. Strain TG-14, a Psychrophilic Bacterium Isolated from Sediment-Laden Stratified Basal Ice from Taylor Glacier,McMurdo Dry Valleys,Antarctica

The psychrophilic bacterium Paenisporosarcina sp. TG-14 was isolated from sediment-laden stratified basal ice from Taylor Glacier, McMurdo Dry Valleys, Antarctica. Here we report the draft genome sequence of this strain, which may provide useful information on the cold adaptation mechanism in extremely variable environments.     

Crystal structure of the inactive state of the receiver domain of Spo0A from <Emphasis Type="Italic">Paenisporosarcina</Emphasis> sp. TG-14, a psychrophilic bacterium isolated from an Antarctic glacier

The two-component phosphorelay system is the most prevalent mechanism for sensing and transducing environmental signals in bacteria. Spore formation, which relies on the two-component phosphorelay system, enables the long-term survival of the glacial bacterium Paenisporosarcina sp. TG-14 in the extreme cold environment. Spo0A is a key response regulator of the phosphorelay system in the early stage of spore formation. The protein is composed of a regulatory N-terminal phospho-receiver domain and a DNA-binding C-terminal activator domain. We solved the three-dimensional structure of the unphosphorylated (inactive) form of the receiver domain of Spo0A (PaSpo0A-R) from Paenisporosarcina sp. TG-14. A structural comparison with phosphorylated (active form) Spo0A from Bacillus stearothermophilus (BsSpo0A) showed minor notable differences. A molecular dynamics study of a model of the active form and the crystal structures revealed significant differences in the α4 helix and the preceding loop region where phosphorylation occurs. Although an oligomerization study of PaSpo0A-R by analytical ultracentrifugation (AUC) has shown that the protein is in a monomeric state in solution, both crosslinking and crystal-packing analyses indicate the possibility of weak dimer formation by a previously undocumented mechanism. Collectively, these observations provide insight into the mechanism of phosphorylation-dependent activation unique to Spo0A.

Genome sequence of the acid-tolerant Burkholderia sp. strain WSM2230 from Karijini National Park,Australia

Burkholderia sp. strain WSM2230 is an aerobic, motile, Gram-negative, non-spore-forming acid-tolerant rod isolated from acidic soil collected in 2001 from Karijini National Park, Western Australia, using Kennedia coccinea (Coral Vine) as a host.

Genomic insights revealed physiological diversity and industrial potential for Glaciimonas sp. PCH181 isolated from Satrundi glacier in Pangi-Chamba Himalaya

Himalayan niches provide unprecedented opportunities for finding novel microbes of commercial importance. The present study investigated the genome sequence of Glaciimonas sp. PCH181 isolated from the glacial stream of Indian trans-Himalaya. The draft genome sequence has six contigs with 5.3 Mb size, 51.1% G + C content, and possesses 4876 genes. Phylogenomic analysis revealed PCH181 as a putative novel bacterium in the genus Glaciimonas. Genomic insight showed Glaciimonas sp. PCH181 enriched with genes for diverse physiology, cold/stress adaptation, and industrial potential. The presence of genes for CO₂ fixation and hydrogen metabolism suggested for chemolithoautotrophy. However, genes for sugars and organic acids usage showed heterotrophy and validated by physiological experiments. Genes for the metabolism of phenol (up to 500 ppm) and biosynthesis of polyhydroxyalkanoate (25% of dry cell mass) were also verified. Collectively, we present the first whole genome sequencing in the genus Glaciimonas, a taxonomically, physiologically, and industrially noteworthy bacterium.     

Whole Genome Analyses of Marine Fish Pathogenic Isolate,Mycobacterium sp. 012931

Mycobacterium is a genus within the order Actinomycetales that comprises of a large number of well-characterized species, several of which includes pathogens known to cause serious disease in human and animal. Here, we report the whole genome sequence of Mycobacterium sp. strain 012931 isolated from the marine fish, yellowtail (Seriola quinqueradiata). Mycobacterium sp. 012931 is a fish pathogen causing serious damage to aquaculture farms in Japan. DNA dot plot analysis showed that Mycobacterium sp. 012931 was more closely related to Mycobacterium marinum when compared across several Mycobacterium species. However, little conservation of the gene order was observed between Mycobacterium sp. 012931 and M. marinum genome. The annotated 5,464 genes of Mycobacterium sp. 012931 was classified into 26 subsystems. The insertion/deletion gene analysis shows Mycobacterium sp. 012931 had 643 unique genes that were not found in the M. marinum strains. In the virulence, disease, and defense subsystem, both insertion and deletion genes of Mycobacterium sp. 012931 were associated with the PPE gene cluster of Mycobacteria. Of seven plcB genes in Mycobacterium sp. 012931, plcB_2 and plcB_3 showed low identities with those of M. marinum strains. Therefore, Mycobacterium sp. 012931 has differences on genetic and virulence from M. marinum and may induce different interaction mechanisms between host and pathogen.

Genome characterization of a novel Burkholderia cepacia complex genomovar isolated from dieback affected mango orchards

We characterized the genome of the antibiotic resistant, caseinolytic and non-hemolytic Burkholderia sp. strain TJI49, isolated from mango trees (Mangifera indica L.) with dieback disease. This isolate produced severe disease symptoms on the indicator plants. Next generation DNA sequencing and short-read assembly generated the 60X deep 7,631,934 nucleotide draft genome of Burkholderia sp. TJI49 which comprised three chromosomes and at least one mega plasmid. Genome annotation studies revealed a total 8,992 genes, out of which 8,940 were protein coding genes. Comparative genomics and phylogenetics identified Burkholderia sp. TJI49 as a distinct species of Burkholderia cepacia complex (BCC), closely related to B. multivorans ATCC17616. Genome-wide sequence alignment of this isolate with replicons of BCC members showed conservation of core function genes but considerable variations in accessory genes. Subsystem-based gene annotation identified the active presence of wide spread colonization island and type VI secretion system in Burkholderia sp. TJI49. Sequence comparisons revealed (a) 28 novel ORFs that have no database matches and (b) 23 ORFs with orthologues in species other than Burkholderia, indicating horizontal gene transfer events. Fold recognition of novel ORFs identified genes encoding pertactin autotransporter-like proteins (a constituent of type V secretion system) and Hap adhesion-like proteins (involved in cell–cell adhesion) in the genome of Burkholderia sp. TJI49. The genomic characterization of this isolate provided additional information related to the ‘pan-genome’ of Burkholderia species.     

Genome sequence of the acid-tolerant Burkholderia sp. strain WSM2232 from Karijini National Park,Australia

Burkholderia sp. strain WSM2232 is an aerobic, motile, Gram-negative, non-spore-forming acid-tolerant rod that was trapped in 2001 from acidic soil collected from Karijini National Park (Australia) using Gastrolobium capitatum as a host. WSM2232 was effective in nitrogen fixation with G. capitatum but subsequently lost symbiotic competence during long-term storage. Here we describe the features of Burkholderia sp. strain WSM2232, together with genome sequence information and its annotation. The 7,208,311 bp standard-draft genome is arranged into 72 scaffolds of 72 contigs containing 6,322 protein-coding genes and 61 RNA-only encoding genes. The loss of symbiotic capability can now be attributed to the loss of nodulation and nitrogen fixation genes from the genome. This rhizobial genome is one of 100 sequenced as part of the DOE Joint Genome Institute 2010 Genomic Encyclopedia for Bacteria and Archaea-Root Nodule Bacteria (GEBA-RNB) project.

Complete genome sequence of Enterobacter sp. IIT-BT 08: A potential microbial strain for high rate hydrogen production

Enterobacter sp. IIT-BT 08 belongs to Phylum: Proteobacteria, Class: Gammaproteobacteria, Order: Enterobacteriales, Family: Enterobacteriaceae. The organism was isolated from the leaves of a local plant near the Kharagpur railway station, Kharagpur, West Bengal, India.
