[Infrared spectra of extreme and obligate thermophilic bacteria of the genus Thermus].

A recording double-beam spectrophotometer UR-10 was used to obtain IR spectra of the extreme thermophilic non-sporeforming bacterium Thermus flavus, the obligate thermophilic non-sporeforming bacterium Thermus ruber, the thermotolerant bacterium Pseudomonas thermophilus, the sporeforming bacterium Bacillus stearothermophilus, and the mesophilic bacteria Pseudomonas aeruginosa, Ps. denitrificans, Flavobacterium breve, Flavobact. arborescens. No significant differences have been found in the IR spectra of these bacteria.
