Abstract:

Phage display technology is a new molecular biological technology, which was gradually established and
developed since the 1980s. Currently there are mainly four types of phages used in the construction of phage display
libraries, including filamentous phage, λ phage, T4 and T7 phage. This technology has extensive applications in screening
specific phages, single-chain antibodies and peptides and establishing food safety detection system. In this article, the system
of phage display technology is described, and its application in the detection of foodborne pathogens is summarized.

Key words: phage display technique, foodborne pathogens, detection
