Microorganisms, which secret a complex of mycolytic enzymes are considered to be possible biological control agents of plant diseases.In this present study, an industrial enzyme chitinase produced by Bacillus species was optimized, purified and its antifungal activity was investigated against plant pathogens. The bacteria Bacillus species was isolated from soil sample and it was identified by staining techniques, plating on selective media and biochemical characteristics. The Bacillus species showed highest chitinolytic activity in Colloidal chitin agars that degrade chitin in 0.6 mm zone of...
