[The Decomposition of Various Types of Crop Residues by Strains Bacillus subtilis IMB B-7516 and B. licheniformis IMB B-7515].

ABSTRACT

It is shown that Bacillus subtilis IMB B-7516 and B. licheniformis IMB B-7515 strains are capable to decomposing crop residues. The effectiveness of the wheat straw decomposition by both strains was 15 - 30 %, sunflower and corn stubble - 40 - 60 % under the laboratory conditions. It is shown the role of pectinase and xylanase activity of the studied strains in the processes of destruction of plant residues. Ammonium nitrate is the best source of nitrogen nutrition for the manifestation of hydrolytic activity by strains Bacillus subtilis IMB B-7516 and Bacillus licheniformis IMB B-7515.
