[show abstract][hide abstract] ABSTRACT: Bacillus coagulans is a ubiquitous soil bacterium that grows at 50-55 °C and pH 5.0 and ferments various sugars that constitute plant biomass to L (+)-lactic acid. The ability of this sporogenic lactic acid bacterium to grow at 50-55 °C and pH 5.0 makes this organism an attractive microbial biocatalyst for production of optically pure lactic acid at industrial scale not only from glucose derived from cellulose but also from xylose, a major constituent of hemicellulose. This bacterium is also considered as a potential probiotic. Complete genome sequence of a representative strain, B. coagulans strain 36D1, is presented and discussed.

[show abstract][hide abstract] ABSTRACT: Kosmotoga olearia strain TBF 19.5.1 is a member of the Thermotogales that grows best at 65°C and very well even at 37°C. Information about this organism is important for understanding the evolution of mesophiles from thermophiles. Its genome sequence reveals extensive gene gains and a large content of mobile genetic elements. It also contains putative hydrogenase genes that have no homologs in the other member of the Thermotogales.

[show abstract][hide abstract] ABSTRACT: Thermotoga sp. strain RQ2 is probably a strain of Thermotoga maritima. Its complete genome sequence allows for an examination of the extent and consequences of gene flow within Thermotoga species and strains. Thermotoga sp. RQ2 differs from T. maritima in its genes involved in myo-inositol metabolism. Its genome also encodes an apparent fructose phosphotransferase system (PTS) sugar transporter. This operon is also found in Thermotoga naphthophila strain RKU-10 but no other Thermotogales. These are the first reported PTS transporters in the Thermotogales.
