Dr. Weitao Geng is an Assistant Professor of the College of Food Engineering and Biotechnology, Tianjin University of Science and Technology. He completed Bachelor and Doctoral Degrees from Nankai University at 2008 and 2014 and joined Tianjin University of Science and Technology as assistant professor till now.

Research Interests

His present research work focus on the probiotic strains isolated from fermental food and their health promote effects. The research work includes: (1) Study on the EPS biosynthesis and function of strain Lactobacillus kefiranofaciens ZW3; (2) Study on the development of novel bifidobacteria strains from fermentation food and their antioxidant effects.
