THE ABILITY OF Trichoderma harzianum TO PRODUCE CHITINASE

The result showed that optimum temperature for maximum activity of Chitinase was 25 Cº with 2.74 unit/µm/min. while optimum pH for maximum activity Chitinase was 5 with 2.25 unit/µm/min . Significant activities of chitinase was produced by T. harzianum in culture media amended with fresh mycelium...

description The result showed that optimum temperature for maximum activity of Chitinase was 25 Cº with 2.74 unit/µm/min. while optimum pH for maximum activity Chitinase was 5 with 2.25 unit/µm/min . Significant activities of chitinase was produced by T. harzianum in culture media amended with fresh mycelium of M. phaseolina , where the releasing of reducing sugar N-acetylglucosamin was 280 µg/ml which Significantly differ from T. harzianum culture media amended with fresh and dry mycelium of R.solani and F.solani where the releasing of reducing sugar N-acetylglucosamin was 200 µg/ml. Production of chitinase using a medium containing chitin reached 40 µg/ml . Maximium chitinase inhibition activity, purified by ammonium sulphate, was recorded for M. phaseolina mycelium growth 47.03% , which Significantly differ with of R.solani and F.solani where the inhibition activity was 35.18 and 33.33% respectively
