Cellolytic Activity of Bacteria of the Bacillus Genus Isolated from the Soil of Zailiskiy Alatau Slopes

This study was conducted for the investigation of
number of cellulolytic bacteria and their ability in decomposition.
Seven samples surface soil were collected on cellulose Zailiskii
Alatau slopes. Cellulolitic activity of new strains of Bacillus, isolated
from soil is determined. Isolated cellulose degrading bacteria were
screened for determination of the highest cellulose activity by
quantitative assay using Congo red, gravimetric assay and
colorimetric DNS method trough of the determination of the
parameters of sugar reduction. Strains are assigned to: B.subtilis,
B.licheniformis, B. cereus and, В. megaterium. Bacillus strains
consisting of several different types of cellulases have broad substrate
specificity of cellulase complexes formed by them. Cellulolitic
bacteria were recorded to have highest cellulase activity and selected
for optimization of cellulase enzyme production.
