ABSTRACT

The aim of this study was to evaluate the effect of cell wall biopolymers
present in biomass of different types of filamentous fungi, yeasts and in biomass
of insects on the expression of lytic enzymes in selected representatives of
filamentous fungi: Trichoderma harzianum T33 and Trichoderma citrinoviride C1.
Dried biomass of filamentous fungi, yeast and insect cells constituted a carbon
source and also acted as an inductor of evaluated enzymes biosynthesis. The biosynthesis
dynamics of chitinases, proteases and laminarinases depending on the type of
inductor introduced into the culture were characterized and compared to the control
cultures, not complemented with the cell wall biopolymers. The differences in
the kinds and level of enzymatic activity, due to the addition of carbon source
were demonstrated. The addition of insect biomass (1%) was the most preferred
for expression of laminarinases and proteases in both Trichoderma strains
(with a little predominance in the C1 strain). Geotrichum and Botrytis biomass
was most effective in the induction of expressed chitinases (with a little predominance
in T33 strain).

Key words: Trichoderma, chitinases, beta-1,3-glucanases, Musca.
