The thermophilic Geobacillus sp. strain FW23 was isolated from the Mehsana oil wells in Gujrat, India, during a screening for oil-degrading bacteria. Here, we report the draft genome sequence of Geobacillus sp. FW23, which may help reveal the genomic differences between this strain and the earlier reported species of the genus Geobacillus.

The genus Geobacillus is comprised of a diverse group of spore-forming Gram-positive thermophilic bacterial species and is well known for both its ecological diversity and as a source of novel thermostable enzymes. Although the mechanisms underlying the thermophilicity of the organism and the thermostability of its macromolecules are reasonably well understood, relatively little is known of the...

Geobacillus sp. Y412MC52 was isolated from Obsidian Hot Spring, Yellowstone National Park, Montana, USA under permit from the National Park Service. The genome was sequenced, assembled, and annotated by the DOE Joint Genome Institute and deposited at the NCBI in December 2011 (CP002835). Based on 16S rRNA genes and average nucleotide identity, Geobacillus sp. Y412MC52 and the related Geobacillu...

We report the 3.3-Mb draft genome of Laceyella sacchari strain GS 1-1, isolated from hot spring water sample, Chumathang, Leh, India. Draft genome of strain GS 1-1 consists of 3, 324, 316 bp with a G + C content of 48.8% and 3429 predicted protein coding genes and 75 RNAs. Geobacillus thermodenitrificans strain NG80-2, Geobacillus kaustophilus strain HTA426 and Geobacillus sp. Strain G11MC16 ar...

Obligately thermophilic, aerobic, proteolytic, endospore-forming strain N-3(T) was isolated from a high-temperature oilfield in Lithuania. 16S rRNA gene sequence analysis placed this strain in genetic group 5 of the endospore formers. Geobacillus thermoleovorans appeared to be the closest phylogenetic neighbour (99.4 % sequence similarity). The G+C content of strain N-3(T) was 52.5 mol% and mat...

Thermophilic bacteria belonging to Bacillus genetic group 5 have been reclassified as being members of Geobacillus gen. nov., with G. stearothermophilus as the type strain. Geobacillus species, literally meaning earth or soil Bacillus, are widely distributed and readily isolated from natural and man-made thermophilic biotopes. Work within our group has however shown that an abundance of genetic...

Nineteen thermophilic, aerobic, endospore-forming bacterial strains were subjected to 16S rRNA gene sequence analysis. Eight of these strains had been received as cultures of Geobacillus kaustophilus, G. lituanicus, G. stearothermophilus, 'G. thermoleovorans subsp. stromboliensis', G. vulcani, 'Bacillus caldolyticus', 'B. caldotenax' and 'B. caldovelox', but they showed close relationships with...

Thermophilic Geobacillus spp. can efficiently hydrolyze hemicellulose polymers and are therefore of interest in biotechnological applications. Here we report the genome sequences of two hemicellulolytic strains, Geobacillus sp. CAMR12739 and CAMR5420.

D-amino acid aminotransferases (D-AATs) from Geobacillus toebii SK1 and Geobacillus sp. strain KLS1 were cloned and characterized from a genetic, catalytic, and structural aspect. Although the enzymes were highly thermostable, their catalytic capability was approximately one-third of that of highly active Bacilli enzymes, with respective turnover rates of 47 and 55 s(-1) at 50 degrees C. The Ge...

The genus Geobacillus includes thermophilic Grampositive spore-forming bacteria that form a phylogenetically coherent clade within the family Bacillaceae. They are of great interest for biotechnology (as discussed below). These thermophiles seem to be ubiquitous; viable Geobacillus spores can be isolated in large quantities not only from hot environments such as hydrothermal vents, but also, pa...
