Suitability of different media for growth and sporulation of local strain of Beauveria bassiana

Studies carried out to determine the effect of different media on the radial growth, sporulation and mycelium weight of Beauveria bassiana revealed that the maximum radial growth on 2 percent malt extract agar and malt mycological agar followed by corn meal agar, Richard's medium, potato dextrose agar, potato carrot agar, malt extract agar and rose bengal agar media, respectively. Highest mycelium (1.76 g dry weight) was harvested from malt extract (mycological peptone) broth followed by Richard's medium (1.18 g), potato dextrose broth (0.51 g), Sabarouds's dextrose broth (0.43 g), malt extract (dextrose peptone) broth (0.35 g), Czapek's dox broth (0.31 g) and potato carrot broth (0.19 g), respectively. Results revealed 2 percent malt extract agar and malt extract (mycological peptone) broth media were the best for growths B. bassiana. Besides, the fungus grown on rice culture showed excellent amount of spore production.
