Cellulolytic Activity of Trichoderma Viride With Regard to Selected Lignocellulosic Waste Materials

Hawrot-Paw M., Izwikow M.

Vol. 17, nr 1

119--122

The aim of the study was to assess the cellulolytic activity of a strain of Trichoderma viride in the presence of three lignocellulosic substrates, i.e. wheat, barley, and maize straw, in different temperatures (25 °C, 30 °C and 35 °C). Research related to the biosynthesis of enzymes was conducted using the deep method, whereas enzyme activity was assessed on solid media with added carboxymethyl cellulose (CMC). The assessment was based on the activity index (AI) determined for each object of research. The obtained results indicate that T. viride produces cellulolytic enzymes, and that their level of activity depends on the type of material introduced into the culture as a lignocellulosic substrate as well as on the temperature. The highest value of AI was found in objects with added maize straw. The optimal temperature for the biosynthesis of cellulolytic enzymes equalled 30 °C.
