Ecological status assessment of microbic population from cespitose-podsolic soil basic saprothrophic microbic pool at the Inzensky field diatomite biochemical destruction

The following paper considers reaction of the saprothrophic and ammoniphycal microbic populations, allocated from the cespitose-podsolic sandy loamy soil of the Nizhny Novgorod Region, to the Inzensky field diatomite substance. On this basis the ecological status of these microorganisms in relation to the studied high-siliceous breed is estimated subsequently. 7-day accumulative cultures of general saprothrophic and ammoniphycal bacteria were used in the study. Living cells were emitted from the cespitose and podsolic soil selected from the Borsky district field «Elitkhoz» by the standard rules in microbiological biotechnology. The result of the research was 30-day dynamics of the breed culture system regarding change of living cells number and proteolytic enzymatic activity of bacterial suspension at biochemical degradation of diatomite substance. The described reaction of microbic complexes in the form of positive dynamics of number and protease activity demonstrates direct destruction interaction of bacterial cultures with diatomite breed that, in turn, can assume their active reaction with this breed and organic substance of the soil with the subsequent release in soil solution of various nutritious elements and in general – stabilization of bacterial L-strategists in the general ecological status of soil microbiocenosis.
