英文摘要:

      Microbial biosensor is a detection device which uses living microbial cells as sensing elements and converted measured information into recognizable signals according to certain rules. Early microbial biosensors appeared in the form of bioassay and bioelectrode. In recent years, with the progress of molecular biology and synthetic biology, genetic engineered microbial biosensors have been rapidly developed, and because of its advantages of low cost, convenience and strong functional scalability, it has good application potential in the field of food safety. This paper introduced the development history and basic principle of microbial biosensor, summarized the latest research results of microbial biosensor in food safety detection, food quality analysis, food safety toxicity assessment, food contamination detoxification, and analyzed the development trend and technical bottleneck of microbial biosensor. This review can provide professional information and technical reference for the research of food safety rapid detection technology and its technicians, so as to promote the further development of microbial biosensors.
