Studies of some physical parameters for large scale protease production by SSF

For designing the large scale protease production system, through solid state fermentation, the important parameters are accumulation density, bed height, aeration etc. The optimum fermentation condition recorded were 0.3125 g/cc accumulation density and 1.0 cm bed height (without aeration). Aeration at 3 LPM and 2.0 cm bed height were found optimum for protease production by Rhizopus oryzae.
