Biography

Dr. Guozhong Zhao is a Associate Professor of the college of Food Engineering and Biotechnology, Tianjin University of Science and Technology. Dr. Zhao completed Bachelor and Doctor Degrees from Tianjin University of Science & Technology at 2008 and 2013 and joined Jiangnan University for the following 4 years as lecture and associate professor, respectively. Since 2017, Dr. Zhao was employed by Tianjin University of Science & Technology as an associate professor.

Research Interests

Aspergillus oryzae plays 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 by A. 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.
