Anoxybacillus flavithermus strain 25 was isolated from a sediment sample from the Garga hot spring in the Barguzin Valley, Baikal Region, Russian Federation (54°19′3.72″N, 110°59′38.4″E). The sequenced and annotated genome is 2,838,680 bp and encodes 3,009 genes.

The Geobacillus icigianus G1w1T strain was isolated from sludge samples of unnamed vaporing hydrothermal (97°С) outlets situated in a geyser in the Troinoy region (Valley of Geysers, Kronotsky Nature Reserve, Kamchatka, Russian Federation; 54°25′51.40″N, 160°7′41.40″E). The sequenced and annotated genome is 3,457,810 bp and encodes 3,342 genes.

The Thermoactinomyces sp. strain Gus2-1 was isolated from hot-spring sediments sample from the hot-spring Gusikha in Bargusin Valley (Baikal Rift Zone, Russia). The sequenced and annotated genome is 2,623,309 bp and encodes 2513 genes. The draft genome sequence of the Thermoactinomyces sp. strain Gus2-1 has been deposited at DDBJ/EMBL/GenBank under the accession JPZM01000000 and the sequences could be found at the site https://www.ncbi.nlm.nih.gov/nuccore/JPZM01000000.
