Enhanced secretion of biocontrol enzymes by Trichoderma harzianum mutant strains in the presence of Rhizoctonia solani cell walls

The secretion of enzymes involved in biocontrol from the wild T. harzianum strains Th11 and Th12 and the mutants Th11A80.1, Th11C40.1 and Th12A10.1 was studied after their cultivation in the presence of R. solani cell walls as the sole carbon source. The results showed that endoprotease activity in...
