Fig. 5From: Isolation and production optimization of a novel milk-clotting enzyme Bacillus velezensis DB219The effects of inoculum size on DB219 MCE production during different fermentation times (12–60 h). The medium composition was wheat bran (60 g/L), soluble starch (10 g/L) and corn steep liquor (3 g/L). a−d Values in the same row with different superscripts are significantly different (P < 0.05).
