Abstract
Two chitinases from Trichoderma harzianum P1 (ATCC 74058) show chitin-containing-fungus- and insect-inhibiting activity. The first is an endochitinase having a molecular weight of 36 kDa and an isoelectric point of 5.3.+-.0.2. The second is an exochitinase having a molecular weight of 36 kDa an an isoelectric point of 4.4.+-.0.2. The chitinases can be applied in contact with chitin-containing fungus or insect as an inhibitor thereof. The chitinases can be applied to plants or to soil around plants which need production from a chitinase-containing pest. The chitinases can also be used to isolate genes coding for them which can be inserted into a genome of a plant needing protection from a chitinase-containing pest or into the genome of a microorganism to provide transgenic microorganism useful to produce enzyme or as a biocontrol agent.
