Lignocellulose is the most abundant plant residue which is composed of cellulose, hemicelluloses and lignin. Some filamentous fungi have developed the ability to use cellulose, hemicelluloses and lignin as energy source. The objective of this research was to analyze the effect of three metal ions (Manganese sulfate, Ferrous sulfate and Zinc sulfate) on the lignocellulolytic activity of four fungal isolates HST11, HST14, HST15 and HST16 under submerged conditions. An experimental design was applied with repetitions consisting of six treatments each for three metal salts (three treatments for cellulolytic activity and three for ligninolytic activity). The lignocellulolytic activities of all the isolates decreased with addition of these metal salts in comparison to medium without addition of any salt. At 0.003 g/L MnSO4, 0.0025 g/L FeSO4 and 0.0015 g/L ZnSO4 maximum cellulolytic activity was observed. Maximum ligninolytic activities were observed at 0.25 g/L concentration of these metal salts.
