Comparative studies on enzyme activities of bacterium (Bacillus subtilis) and Nigerian edible fungi (Termitomyces clypeatus, Termitomyces globulus, Pleurotus tuber-regium, and Agaricus sp)

Segun Gbolagade Jonathan, Olusegun Richard Adeoyo

Enzyme activities of Termitomyces clypeatus, Termitomyces globulus, Pleurotus tuber-regium, andAgaricus sp (edible Nigerian fungi) were compared with that of Bacillus subtilis (a bacterium) which have been known to be a very good amylase producer. In these studies, Pleurotus tuber-regium and Agaricus sp had amylase activities values of 0.45 and 0.39 U/min respectively. Bacillus subtilis had highest amylase value with yeast extract (0.63U/min) and least valuewithNaNO3 (0.35unit/min). For cellulase activity, Bacillus subtilis had value of 0.4unit/minwith yeast extractwhileCoriolus vesicolor, Pleurotus tuber-regium and Termitomyces clypetus had values of 0.67,0.59 and 0.51 U/min respectively. Temperature and pH also had significant effect on the production of these enzymes.
