In solid-state fermentation (SSF), interaction of heat and mass transfer with biochemical reaction (growth associated enzyme production) affects the bioreactor performance. This interaction was earlier observed to cause temperature and gaseous concentration gradients which reduced the effective bed height of the bioreactor. Since forced aeration is known to alleviate this problem, a packed column bioreactor with forced aeration was employed in the present study. Using wheat bran and Aspergillus… CONTINUE READING
