Application Aspergillus oryzae
Jual culture Dan Starter Aspergillus oryzae Telp. 087731375234 Studies of A. oryzae and A. sojae strains used for shoyu production have focused on comparing these two fungal species and improving their enzyme-producing abilities. A study of the enzymatic differences between 11 strains of A. oryzae and 20 strains of A. sojae showed that the activities of neutral, acid, and alkaline proteases, xylanase, pectin lyase, phosphatase, and aminopeptidase were not significantly different. However, acid carboxy peptidase activity and α-amylase activity were higher from A. oryzae when compared with A. sojae strains, while endopolygalacturonidase activity was much higher from A. sojae than from A. oryzae (Terada et al., 1980). The ratios between α-amylase activity and endopoly galacturonidase activity of 0.5–2 for A. sojae and 20–2000 for A. oryzae were suggested as a differentiation criterion for the species (Terada et al., 1980). Hayashi et al. (1981) compared the performanc...
