DOIAbstract
The article provides some information about spore-forming bacteria (bacilli) and micromycetes of natural (virgin) stenosis under herbaceous vegetation and agrocenosis (cereals). It was established that in both senses there are 3 strains of spore-forming bacteria and 4 strains of micromycetes. Bacilli and micromycetes actively decompose complex polysaccharides to monosaccharides, which are easily absorbed by plants. Bacilli and micromycetes have a strong enzymatic effect on plant residues, transforming decomposition products in the process of humus formation. Together with invertebrate animals, they are included in the decomposition chain of phytomass residues. Bacilli and micromycetes, being active under mesophilic conditions, are also sign...
