[Substantiation and assessment of the effectiveness of hygienic recommendations for healthier work conditions of operators at seismic-acoustic stations].

The labour conditions of seismic operators were studied as a sample of similar professions engaged in acoustic control services. Depending on the number of the sectors under control and the seismic activity in the area, the enthropy of the sounds controlled and the information volume were assessed within 2.2-2.

[Thermogenesis of mesophilic, thermotolerant and thermophilic strains of microorganisms--producers of fungal cell wall--destroying enzymes].

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.
