Analysis of extracellular proteins of Aspergillus oryzae grown on soy sauce koji.
Aspergillus oryzae AS 3.951 is widely used in Chinese soy sauce manufacture, but little is known about the profiles of the extracellular proteins from the culture of soybean koji. In this study, we carried out MALDI-TOF/TOF MS analysis of extracellular proteins during koji culture. Besides well-known proteins (TAA and Oryzin), a variety of aminopeptidase and proteases were identical at the proteome level. This suggests that A. oryzae AS 3.951 has a powerful capacity to digest soybean protein.
