Abstract
Abstract
Prophage vB_LdeS-phiJB (phiJB) was induced by mitomycin C and UV radiation from the Lactobacillus delbrueckii subsp. bulgaricus SDMCC050201 isolated from a Chinese yoghurt sample. It has an isometric head and a non-contractile tail with 36,969 bp linear double-stranded DNA genome, which is classified into the group a of Lb. delbrueckii phages. The genome of phiJB is highly modular with functionally related genes clustered together. Unexpectedly, there is no similarity of its DNA replication module to any phages that have been reported, while it consists of open-reading frames homologous to the proteins of Lactobacillus strains. Comparative genomic analysis indicated that its late gene clusters, integration/lysogeny modules and DNA replication module derived from different evolutionary ancestors and integrated into a chimera. Our results revealed a novel chimeric phage of commercial Lb. delbrueckii and will broaden the knowledge of phage diversity in the dairy industry.
