[Character of interactions of saprophytic soil microflora via gaseous metabolites].

The character of interaction between saprophytic soil bacteria via gaseous metabolites was studied. It was established that, at the metabolic level, a diverse character of interspecies interrelationships between bacteria exist, directly influencing their reproduction and preservation in soil. Volatile compounds produced by bacteria are able to act as both intra- and interspecies regulators of microbial communities. The soil microbiocenosis composition may be therefore regulated by volatile products of metabolism of saprophytic soil bacteria. Methanol released by bacteria into the environment plays an important role in this process.
