Abstract: With the extensive application of Lactobacilli for the dairy industry, phage contamination has posed an increasingly serious threat to the final products. Currently, phage research has evolved from the morphological to the molecular level. The full-length genomic sequences of many phages have been acquired. Genomic studies have contributed to revealing the infective mechanisms of phages and in turn exploring the key functional genes. In this paper, the genomic characteristics, functional genomics and comparative genomics of the major Lactobacillus phages published were analyzed, aiming to provide a theoretical basis for further exploration of phages.

Key words: Lactobacillus, phage, genomics
