Abstract
A fungal strain belonging to the genus Penicillium was isolated from soil sample and has been diagnosed as Penicillium sp. according to its morphological characteristics of the colonies on solid media and also microscopical examination of the fungal parts. Antibiotics, protease activity and pH values were determined after cultivation of the fungus using submerged fermentation (SF) and solid state fermentation (SSF). The two different patterns of fermentation processes seem to influence the physiological behavior of the fungus differently. Experiments were made using nutrient broth medium (N.B) for SF and wheat bran in SSF. The pH values were adjacent to 5.5. Whe...
