[Thermogenesis of mesophilic, thermotolerant and thermophilic strains of microorganisms--producers of fungal cell wall--destroying enzymes]. / Termogenez mezofil'nogo, termotolerantnogo i termofil'nogo shtammov mikroorganizmov--produtsentov fermentov, razrushaiushchikh kletochnye stenki drozhzhei

Investigations were carried out to clarify the relationship between thermogenesis and production of yeast wall lyzing enzymes by the mesophilic strain of Bacillus subtilis, thermotolerant strain of Actinomyces sp. II and thermophilic strain of Actinomyces sp. 10. The enzymic lyzing activity was measured in the culture liquid filtrate of those microorganisms. The thermophilic strain of Actinomyces sp. 10 showed the highest enzymic activity. The thermogenetic curves of the cultures had several inflections. The mesophilic culture of Bacillus subtilis whose enzymic lyzing activity was the lowest displayed the highest heat release.

A technique is proposed for continuous measurements of heat production and solved oxygen during the cultivation of bacteria and production of (purple membranes). Interrelationship between heat production and pO2 during the cultivation of halophile is investigated.
