ABSTRACT



In this paper the capability of eight strains of yeasts Geotrichum candidum for cellulases and xylanases production in two mineral media with addition of various components was examined. Mineral media were supplemented with four different sources of carbon, such as sugar beet pulp, wheat grain, CMC or glucose. Geotrichum candidum strains were characterized very different level of cellulase and xylanase biosynthesis. The highest cellulase activities for 6 strains from 8 ascertained in Saunders medium with sugar beep pulp and in MGP medium with a CMC. However highest xylanase activities observed in both media with CMC. Some strains produced cellulases and xylanases in mineral medium when glucose used as carbon sources.

Key words: Geotrichum candidum, cellulase, xylanase.
