Complete genome sequence of a bacterium representing a deep uncultivated lineage within the Gammaproteobacteria associated with the degradation of polycyclic aromatic hydrocarbons.

The bacterial strain TR3.2, representing a novel deeply branching lineage within the Gammaproteobacteria, was isolated and its genome sequenced. This isolate is the first cultivated representative of the previously described “Pyrene Group 2” (PG2) and represents a variety of environmental sequences primarily associated with petrochemical contamination and aromatic hydrocarbon degradation.

An improved high-quality draft genome sequence of Carnobacterium inhibens subsp. inhibens strain K1(T).

Despite their ubiquity and their involvement in food spoilage, the genus Carnobacterium remains rather sparsely characterized at the genome level. Carnobacterium inhibens K1(T) is a member of the Carnobacteriaceae family within the class Bacilli. This strain is a Gram-positive, rod-shaped bacterium isolated from the intestine of an Atlantic salmon. The present study determined the genome sequence and annotation of Carnobacterium inhibens K1(T). The genome comprised 2,748,608 bp with a G?+?C content of 34.85 %, which included 2621 protein-coding genes and 116 RNA genes. The strain contained five contigs corresponding to presumptive plasmids of sizes: 19,036; 24,250; 26,581; 65,272; and 65,904 bp.

Near-complete genome sequence of Thalassospira sp. strain KO164 isolated from a lignin-enriched marine sediment microcosm.

Thalassospira sp. strain KO164 was isolated from eastern Mediterranean seawater and sediment laboratory microcosms enriched on insoluble organosolv lignin under oxic conditions. The near-complete genome sequence presented here will facilitate analyses into this deep-ocean bacterium’s ability to degrade recalcitrant organics such as lignin. Copyright © 2016 Woo et al.

Serinibacter

The genus Serinibacter belongs, based on the phylogenetic analysis of the nearly full-length 16S rRNA gene, to the Beutenbergiaceae together with the genera Beutenbergia, Salana, and Miniimonas. The two species of the genus Serinibacter shared 99.6% 16S rRNA gene sequence similarity but low DNA DNA relatedness. Cells are irregular rods, Gram-stain positive, not acid-fast. Endospores are not formed. Nonmotile. Aerobic to anaerobic. Oxidase-negative, catalase-positive. The peptidoglycan type is A4a with an l-Ser residue at position 1 of the peptide subunit. The acyl type is acetyl. The major cell-wall sugar is galactose. The predominant menaquinone is MK-8(H4). The major polar lipids consist of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, and unidentified phospholipids. Phosphatidylethanolamine is absent. The cellular fatty acid profile is dominated by the occurrence of iso- and anteiso-branched-chain acids. Mycolic acids are absent. The genomic G+C content is 70.7 to 72.8 mol%.

High- quality draft genome sequences of eight bacteria isolated from fungus gardens grown by Trachymyrmex septentrionalis ants.

For their food source, Trachymyrmex septentrionalis ants raise symbiotic fungus gardens that contain bacteria whose functions are poorly understood. Here, we report the genome sequences of eight bacteria isolated from these fungus gardens to better describe the ecology of these strains and their potential to produce secondary metabolites in this niche.
