PCR AMPLIFICATION OF CELLULOSE-DEGRADING ENDOGLUCANASE AND Β-GLUCOSIDASE GENES OF BACILLUS SUBTILIS STRAINS

The given article presents that the main part of animal feed is plant products. The decomposition of cellulose in the cell shell of plants and the assimilation of the resulting products are considered one of the factors that determine the productivity of the organism. In this restriction, genes involved in cellulose degradation were screened in 8 strains of B. subtilis isolated from the digestive system of animals. The β-glucosidase gene was detected by PCR in all B. subtilis strains. Endoglucanase gene was found to be present in B. subtilis 1, B. subtilis 2, B. subtilis 3, B. subtilis 7 and B. subtilis 8 strains.
