Chitinase production ability of Trichoderma harzianum isolates by Turbidity method

Abstract

Fungi in the genus Trichoderma are among the most promising biocontrol agents against plant-pathogenic fungi. Specific strain have ability to control a range of pathogens under a variety of environmental conditions. In this study, total five isolates of Trichoderma harzianum were studied. Three were isolated from rhizosphere soil of different places i.e., TH2, TH3, TH4 and two isolates procured from different places i.e., TH1 and TH5. Recently, a few chitinolytic enzymes from T. harzianum Rifai were purified and characterized, the availability of purified chitinolytic enzymes from Trichoderma permits studies on their effects against other fungi. The data presented in table 1, showed that TH1 (T1) content maximum i.e. 0.65 chitinase enzyme units/ mg of protein units.
