Summary

The cellulolytic activity of the culture filtrates of two strong cellulose decomposers namely Penicillium oxalicum and Helminthosporium cyclops was studied. The culture age influenced markedly the cellulolytic activity and two weeks of growth were found to establish the highest activity. The highest activity was recorded at pH 4 and pH 5 in case of Penicillium oxalicum and Helminthosporium cyclops respectively. In both experimental fungi, 40° C was the most suitable temperature for the cellulolytic action. The cellulase activity of the filtrate was found to be comparatively stable for a long time. The cellulase enzymes of both organisms were found to be strongly adaptive.
