Abstract: | Chitinolytic prokaryotic and eukaryotic complexes were studied in the course of succession initiated by an introduction of chitin and moistening of the soil. An increase in the number and biomass of chitinolytic microorganisms and stronger carbon dioxide emission were observed in the experimental variants with chitin as compared with the control without chitin. The increase was recorded for the prokaryotes (actinomycetes and bacteria) and not due to the eukaryotes in the course of the succession initiated by chitin. It was first found that the chitinolytic actinomycetal complex in an ordinary chernozem has a specific taxonomic structure. The representatives of the Streptosporangium genus were the dominating actinomycetes in the chitinolytic complex. |
