MICROBIOLOGICAL DIAGNOSTICS OF PEAT SOILS ON THE BASIS OF SUCCESSIVE TRANSFORMATIONS OF ACTINOMYCES COMPLEX

Population dynamics of Actinomycetales (Streptomyces, Saccharomonospor a, Micromonospora, and Streptosporangium genera) were investigated in the course of successions, induced by moistening peat soil samples to different degrees of soil moisture pressure. It is shown that successi ve transformations of actinomyces depend significantly on the soil moi sture status. Based on succession changes in populations of actinomyce s, the differentiae criteria for diagnostics of the degree of cultivat ion and moistening of peat soils are suggested. These are: (1) changes in population and species diversity of actinomyces extracted from pea t soil in the course of the succession induced by moistening and (2) p revalence of certain species of actinomyces at different stages of suc h successions. The major differentiae ecological features (level of mo istening, period of succession, and abundance index) for four genera o f actinomyces (Streptomyces, Saccharomonospora, Micromonospora, and St reptosporangium) are determined. A mathematical model is proposed for evaluating the degree of cultivation and moistening of peat soil on th e basis of the structure of its actinomyces complex.
