Abstract: | The rumen anaerobic fungus Caecomyces communis was grown in a fermentor in Lowe medium. We studied four polysaccharide hydrolases and three glycoside hydrolases at early
and final stages. We found a difference in cell association for these enzymes depending on the developmental stage. The endocellulase
and β-D-fucosidase were early synthesized, and their activities decreased at the end of the developmental cycle. On the contrary,
the β-D-glucosidase, β-D-xylosidase and xylanase activities increased during the cycle. The avicelase and the CM-cellulase
activities linked with thalli increased, whereas the extracellular activities of these enzymes decreased. |
