Geobacillus sp. strain GHH01 was isolated during a screening for producers of extracellular thermostable lipases. The completely sequenced and annotated 3.6-Mb genome encodes 3,478 proteins. The strain is genetically equipped to utilize a broad range of different substrates and might develop natural competence.

Studies of bacteriophages GH5 and GH8 of Bacillus stearothermophilus strain NCA1518 revealed that their properties were sufficiently different from known phages and from each other to indicate that each was a different entity, although no major deviation was demonstrated.

The industrially important thermophile Geobacillus thermoglucosidasius has the potential to produce chemicals and fuels from biomass-derived sugar feedstocks. Here, we present the genome sequence of strain NCIMB 11955, the progenitor of an ethanologenic industrial strain, revealing 11 single-nucleotide polymorphisms and 2 indels compared to strain DSM 2542 and two novel plasmids.

The draft genome sequence of Geobacillus subterraneus strain K, a thermophilic aerobic oil-oxidizing bacterium isolated from production water of the Uzen high-temperature oil field in Kazakhstan, is presented here. The genome is annotated for elucidation of the genomic and phenotypic diversity of thermophilic alkane-oxidizing bacteria.

There are several natural examples of distinct RNA structures that interact with the same ligand to regulate the expression of homologous genes in different organisms. One essential question regarding this phenomenon is whether such RNA regulators are the result of convergent or divergent evolution. Are the RNAs derived from some common ancestor and diverged to the point where we cannot identif...

Here, we report the draft genomes of five strains of Geobacillus spp., one Caldibacillus debilis strain, and one draft genome of Anoxybacillus flavithermus, all thermophilic spore-forming Gram-positive bacteria.

The heat resistances of the fully demineralized H-form spores of Bacillus megaterium ATCC 19213, B. subtilis var. niger, and B. stearothermophilus ATCC 7953 were compared with those of vegetative cells and native spores to assess the components of resistance due to the mineral-free spore state, presumably mainly from dehydration of the spore core, and to mineralization. Mineralization greatly i...

Bacillus stearothermophilus BR219, isolated from river sediment, degraded phenol at levels to 15 mM at a rate of 0.85 mumol/h (4 x 10(6) cells). The solubilized phenol hydroxylase was NADH dependent, exhibited a 55 degrees C temperature optimum for activity, and was not inhibited by 0.5 mM phenol.

The 5 A resolution crystal structure analysis of ribosomal protein L30 from Bacillus stearothermophilus is described. The molecule is shown to be compact and extend to about 25-30 A in each dimension.

Crystals of ribosomal protein L6 from Bacillus stearothermophilus suitable for high resolution structural studies have been obtained. Crystals are hexagonal with space group P6122 (or the enantiomorph P6522) and cell dimensions a = b = 72.7 A, c = 124.9 A. A search for heavy atom derivatives is in progress.
