Abstract
A phage and use thereof in soil remediation are disclosed. The phage φYSZPK has been deposited at the China Center for Type Culture Collection on Aug. 1, 2018 under Accession No. CCTCC M 2018516, and its taxonomic designation is Pseudomonas aeruginosa and Klebsiella phage φYSZPK. Biochar and the screened phage are combined and returned into contaminated soil to synergistically control and deeply track and inactivate transmission and spread of antibiotic resistance pathogenic bacteria and resistance genes in a soil-vegetable system. The combination of the biochar and the phage φYSZPK not only clearly improves the functional stability of microbial community in the soil-vegetable system, but also significantly alleviates the dissemination of the antibiotic resistance pathogenic bacteria in the soil-vegetable system to prevent secondary pollution, thereby providing a new solution for biological remediation and control of farmland soil contaminated by antibiotic resistance pathogenic bacteria in China.
