Liu, Shuangping Ph.D., Assistant Professor Tel:+86-15006180852 E-mail:[email protected] Areas of Expertise:Fermentation Food 2005-Present Assistant Professor,Jiangnan University, PRC 2005-2015 Undergraduate Student, PhD Candidate, Jiangnan University, PRC Research Interest The microbial ecology of Chinese traditional fermentation food Chinese traditional fermentation foods have developed more than 5,000 years, and they are still very popular in Chinese. Their market was more than $2 trillion. Chinese rice wine, liquor, black vinegar, soy sauce, Chinese sauerkraut, stinky mandarin fish and Chinese ham are popular fermentation foods in China. These foods are still been produced in a traditional multispecies co-fermentation process which was naturally driven by reproducible microbiota. The flavor and healthy compounds in these foods were mostly produced by microbiota in food ecosystem, while, some harmful compounds like biogenic amines and ethyl carbamate were also produced by them. However, the associations between microbiota and key compound-producing are still poorly understood. Thus the fermentation process of Chinese rice wine was takes as a typical multispecies co-fermentation process. Microbial metabolism of food production Aromatic compounds like phenylethanol and phenylacetic acid are key flavors in most fermentation foods. Their biosynthesis pathway was one of the most complicate metabolic pathways in microorganisms. A phenylpyruvate derivatives producing chasis was constructed using systems level engineering, then the metabolic pathways and regulation sites were reviewed for aromatic compounds synthesis. Then it was found that Saccharomyces cerevisiae CRWY for huangjiu brewing possessed a distinct metabolic regulation mechanism in β-phenylethanol synthetic pathway, especially the Pha2p was feedback inhibited by L-phenylalanine.
