respectively isolated from deep subterranean petroleum reservoirs in the Minami-aga
(Niigata) and Yabase (Akita) oil fields. Both strains were able to grow at temperatures
ranging from 50 to 80° C, with optimal growth at 70° C for B23 and 65° C for H41. From 16S
rRNA gene sequence analysis and physiological characterization, both strains were
identified as Bacillus thermoleovorans (identities of 99.5% and 99.6% to strain DSM 5366 …
