Okara, a soymilk residue is produced in huge quantities in soymilk industries. In the present investigation three combinations of Okara and wheat grits where prepared in the ratio of 3:1 (60% moisture content), 1:1 (40% moisture content), 1:3 ( 25 % moisture content) respectively. The combinations were inoculated with two fungal species viz. Rhizopus oligosporus and Aspergillus oryzae, with an inoculum size of 1.0 x I0 3 , 1.0 x I0 4 and 1.0 x I0 5 cfu per g substrate. The combinations were incubated at different temperatures i.e. 200 c, 250 c and 300 c. The combinations were finally analyzed for the effective inoculum size, incubation temperature and nucleic acid concentration. The results obtained depict that the best inoculum size for maximum SCP yield was 1.0 x I0 3 cfu per g substrate. The best incubation temperature was found to be 250 c. The maximum nucleic acid concentration was found to be 249 mg for R. oligosporus and 260 mg for A. oryzae.
