Biography

Dr. Xinjun Du is a Professor and Vice Dean of the college of Food Engineering and Biotechnology, Tianjin University of Science and Technology. Dr. Du completed Bachelor and PhD Degrees from Shandong University at 2001 and 2007, respectively. On the completion of his Ph.D, Dr. Du was employed by Tianjin University of Science & Technology as a lecturer. At 2009, he was employed as an associate professor. Four years after that, he was employed as a professor at 2013. He published over 40 scientific papers.

Research Interests

Bacterial foodborne pathogens greatly threaten peoples’ health and are becoming one of the most important food safety problems all over the world. Bacterial foodborne pathogens have an outstanding feature of multiplying rapidly under certain conditions during food storage, and therefore cause some unpredictable damage to peoples. Dr. Du has interest in understanding how the bacterial foodborne pathogens survive in the environment, contaminate food and damage human beings. In his recent work, random mutation, genome sequencing, transcriptome sequencing and proteomics identification techniques were used to screen some factors involved in biofilm formation, desiccation tolerance and pathogenic features. Gene knock-out technique was mainly used to further investigate the roles of the obtained genes or proteins after screening. Up to date, many new functions of different genes were experimentally determined. These studies greatly improve our understanding how the bacterial foodborne pathogens can damage peoples.

   Furthermore, Dr. Du is also interested in rapid detection of bacterial foodborne pathogens. Most standard methods for bacterial foodborne pathogens detection are time-consuming and laborious. These weaknesses greatly limit transportation of food product. Using specific antibodies and isothermal amplification methods, in combination with strips, many rapid detection methods for bacterial foodborne pathogens detection were developed. Most of the methods can be finished within six hours with great sensitivity for real food sample detection. Several bacterial cells contaminated in food samples can be successfully identified. Some methods can be used to quantitatively detect bacterial foodborne pathogens in food samples. These studies are greatly helpful to develop and apply rapid detection methods for bacterial pathogens detection.
