    Abstract:
    Screening of aerobic sporulating bacteria of Bacillus genus from the collection of IMV ofNAS of Ukraine was performed to search for producers of cellulosolytic enzymes. Only 206 strains (58.4%) of 353 studied bacteria strains are capable to decompose carboxymethylcellulose, 158 strains (44.8%)--cellobiose. Under these conditions 91 strains (25% of all studied ones) synthesized actively both endoglucanase and cellobiase. It was shown that biosynthesis of enzymes of cellulose complex in bacilli was of inducible character, white the composition and activity of its components was a regulated process and was determined both by physiologic features of strains and by the conditions of their cultivation, composition of nutrient medium in particular. The strains of bacilli with high level of fermentation activity were selected as a result of screening.
