ABSTRACT

“Cellulolysis rate” of the pathogenic fungus, Drechslera ellisii was studied on filter paper
discs. There was positive correlation between the growth of the fungus and weight loss of the
filter paper. The weight loss caused by the fungus was influenced by nitrogen content of the
nutrient solution and pH. It increased with increasing concentration of nitrate content and was
maximum at pH 5 .0 of the nutrient solution.
