Draft Genome Sequence of Cyanobacterium sp. Strain HL-69, Isolated from a Benthic Microbial Mat from a Magnesium Sulfate-Dominated Hypersaline Lake

ABSTRACT The complete genome sequence of Cyanobacterium sp. strain HL-69 consists of 3,155,247 bp and contains 2,897 predicted genes comprising a chromosome and two plasmids. The genome is consistent with a halophilic nondiazotrophic phototrophic lifestyle, and this organism is able to synthesize most B vitamins and produces several secondary metabolites.

High-Quality Draft Genome Sequence of the Opitutaceae Bacterium Strain TAV1, a Symbiont of the Wood-Feeding Termite Reticulitermes flavipes

Microbial communities in the termite hindgut are essential for degrading plant material. We present the high-quality draft genome sequence of the Opitutaceae bacterium strain TAV1, the first member of the phylum Verrucomicrobia to be isolated from wood-feeding termites. The genomic analysis reveals genes coding for lignocellulosic degradation and nitrogen fixation.

Draft Genome Sequences for Clostridium thermocellum Wild-Type Strain YS and Derived Cellulose Adhesion-Defective Mutant Strain AD2

Clostridium thermocellum wild-type strain YS is an anaerobic, thermophilic, cellulolytic bacterium capable of directly converting cellulosic substrates into ethanol. Strain YS and a derived cellulose adhesion-defective mutant strain AD2 played pivotal roles in describing the original cellulosome concept. We present their draft genome sequences.

Draft Genome Sequence of Rubrivivax gelatinosus CBS

Rubrivivax gelatinosus CBS, a purple nonsulfur photosynthetic bacterium, can grow photosynthetically using CO and N{sub 2} as the sole carbon and nitrogen nutrients, respectively. R. gelatinosus CBS is of particular interest due to its ability to metabolize CO and yield H{sub 2}. We present the 5-Mb draft genome sequence of R. gelatinosus CBS with the goal of providing genetic insight into the metabolic properties of this bacterium.

Genome sequences for six Rhodanobacter strains isolated from soils and the terrestrial subsurface with variable denitrification capabilities

We report the first genome sequences for six strains of Rhodanobacter species isolated from a variety of soil and subsurface environments. Three of these strains are capable of complete denitrification and three others are not. However, all six strains contain most of the genes required for the respiration of nitrate to gaseous nitrogen. The nondenitrifying members of the genus lack only the gene for nitrate reduction, the first step in the full denitrification pathway. The data suggest that the environmental role of bacteria from the genus Rhodanobacter should be reevaluated.

Complete Genome Sequence of Desulfurococcus fermentans, a Hyperthermophilic Cellulolytic Crenarchaeon Isolated from a Freshwater Hot Spring in Kamchatka, Russia

Desulfurococcus fermentans is the first known cellulolytic archaeon. This hyperthermophilic and strictly anaerobic crenarchaeon produces hydrogen from fermentation of various carbohydrates and peptides without inhibition by accumulating hydrogen. The complete genome sequence reported here suggested that D. fermentans employs membrane-bound hydrogenases and novel glycohydrolases for hydrogen production from cellulose.

Complete Genome Sequence of the Thermophilic, Piezophilic, Heterotrophic Bacterium Marinitoga piezophila KA3

Marinitoga piezophila KA3 is a thermophilic, anaerobic, chemoorganotrophic, sulfur-reducing bacterium isolated from the Grandbonum deep-sea hydrothermal vent site at the East Pacific Rise (13 degrees N, 2,630-m depth). The genome of M. piezophila KA3 comprises a 2,231,407-bp circular chromosome and a 13,386-bp circular plasmid. This genome was sequenced within Department of Energy Joint Genome Institute CSP 2010.

Whole-Genome Sequences of Borrelia bissettii Borrelia valaisiana and Borrelia spielmanii

It has been known for decades that human Lyme disease is caused by the three spirochete species Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii. Recently, Borrelia valaisiana, Borrelia spielmanii, and Borrelia bissettii have been associated with Lyme disease. We report the complete genome sequences of B. valaisiana VS116, B. spielmanii A14S, and B. bissettii DN127.

Complete Genome Sequence of Desulfobulbus oligotrophicus Prop6, an Anaerobic Deltabacterota Strain That Lacks Mercury Methylation Capability

Desulfobulbus oligotrophicus Prop6 is a sulfate-reducing, propionate-oxidizing Deltabacterota (formerly Deltaproteobacteria) strain from sewage sludge. Desulfobulbus species are found in anoxic environments, in animal microbiota, and some produce the neurotoxin methylmercury. The 3.1-Mbp D. oligotrophicus genome sequence enables studies of diverse environmental adaptations and the evolutionary genomics of mercury methylation mechanisms.

Draft Genome Sequence of Pedococcus sp. Strain 5OH_020, Isolated from California Grassland Soil

The draft genome sequence of the soil bacterium Pedococcus sp. strain 5OH_020, isolated on a natural cobalamin analog, comprises 4.4 Mbp, with 4,108 protein-coding genes. Its genome encodes cobalamin-dependent enzymes, including methionine synthase and class II ribonucleotide reductase. Taxonomic analysis suggests that it is a novel species within the genus Pedococcus .
