Aspergillus oryzaeplays a central role in soy sauce fermentation, because it can produce a lot of enzymes which are used to decompose raw materials. The enzymes can make a great contribution to the flavor of soy sauce. During post-fermentation, different organic acids may be from A. oryzae metabolizing sugars. Neutral and alkaline protease activities decline with the decrease in pH in fermentation broth. However, seldom acid protease is secreted byA. oryzae 3.042. So the utilization of raw material was low and we were not satisfied with the flavors in soy sauce. In our present work, A. oryzae which can secrete more acid proteases was isolated and screened. The genomes and transcriptomes of A. oryzae 3.042 and A. oryzae 100-8 were sequenced and analysed, and their proteomics were also researched. These projects laid a foundation for the development of cell factory and metabolic engineering.
