[Dynamics of the accumulation and retention of volatile organic substances released by bacteria].

The object of this work was to study the production of volatile biologically active compounds by microorganisms and their accumulation in the medium in the course of several days. The inhibiting action of the accumulated volatile metabolites was found to depend on the time within which the culture was incubated and on the sensitivity of the test organism. The activity of the accumulated metabolites was shown to decrease with the time of storage. Several volatile compounds were found among the metabolites.
