Abstract

A rapid and convenient method for the detection of chitinases accumulating in filamentous fungal cultures was developed. The assay is performed on cultures growing in microtiter plates, with a fluorogenic substrate: 4-methylumbelliferyl-N-acetyl-D-glucosaminide (4-MeUNAG). The fluorescence of the product, 4-methylumbelliferone, was detected. This method was successfully used to follow induction and repression of extracellular exochitinase activity in the biocontrol fungus Trichoderma harzianum. (C) 2001 Elsevier Science B.V.
