Fusarium subglutinans (Wollenweber and Reinking) Nelson et al. was found to produce intracellular milk-clotting enzyme (MCE) with good milk-clotting activity (MCA). The crude activity of the produced enzyme was recorded as optimum at 55 degrees C and pH 4.5. The highest yield i.e. 78.43 SU/mg dry biomass was obtained after 4 days of rotary shaking at 30 degrees C when the fermentation medium containes wheat flour 2%, glucose 1% and (NH4)2SO4 0.1% with an initial pH value 6.0. Under these conditions, the maximum ratio of MCA to proteolytic activity (PA) amounting to 603.31 SU/PU mg(-1) was also achieved. Production of intracellular MCE by F. subglutinans was assumed to be active growth-associated type. This enzyme preparation was less active than the calf rennet, but was superior to those of Meito's and Pfizer's rennets.

Studies on the extraction of milk-clotting enzyme after solid-state fermentation (SSF) of wheat bran by a local strain of Aspergillus oryzae LS1 were done. The extraction of the enzyme was found to be depended on different parameters like nature of extractant, soaking time, temperature etc. From different inorganic and organic extractants, calcium chloride (0.05%) and glycerol (40%) were found to be the best solvents for leaching out milk-clotting enzyme. The optimum volume of calcium chloride was 5 ml/g biomass. An extraction time of 180 min. at 30 degrees C and 100 rpm was sufficient to extract out nearly 28% of the enzyme (2666.7 U/g biomass). Most of the enzyme (about 98.71%) was recovered in four repeated extractions.
