Patent number: 11192155Abstract: A phage and use thereof in soil remediation are disclosed. The phage ?YSZPK 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 ?YSZPK. 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 ?YSZPK 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.Type: GrantFiled: August 21, 2019Date of Patent: December 7, 2021Assignee: INSTITUTE OF SOIL SCIENCE, CHINESE ACADEMY OF SCIENCESInventors: Mao Ye, Yuanchao Zhao, Mingming Sun, Zhongyun Zhang, Dan Huang, Yongrong Bian, Feng Hu, Xin Jiang

Publication number: 20200063109Abstract: A phage composition and use thereof in inactivating antibiotic resistance pathogenic bacteria are disclosed. The phage composition includes three phages, and the phages all have been deposited at the China Center for Type Culture Collection on Aug. 1, 2018. The phages are a phage ?YSZKA under Accession No. CCTCC M 2018513, a phage ?YSZKP under Accession No. CCTCC M 2018514, and a phage ?YSZPA under Accession No. CCTCC M 2018515, respectively. The present invention provides a remediation method by applying a specific bacteriophage stock solution into a contaminated soil-plant system to directionally infect and inactivate a combined contamination of resistance pathogenic bacteria in the system and synergistically remove antibiotic resistance genes. In addition, the functional diversity and stability of a soil ecological environment are significantly restored, after the remediation.Type: ApplicationFiled: August 21, 2019Publication date: February 27, 2020Applicant: Institute of Social Science, Chinese Academy of SciencesInventors: Mao YE, Yuanchao ZHAO, Mingming SUN, Zhongyun ZHANG, Dan HUANG, Xin JIANG
