The present invention discloses a strain of Pseudomonas aeruginosa ZC6, which provides a heavy metal ion Zn<2+> removing effect. The method for screening Pseudomonas aeruginosa providing a heavy metal ion Zn<2+> removing effect from soil and water comprises: a, preparing a metal selective culture medium; b, carrying out enrichment acclimatization on a heavy metal resistance strain; c, screening and re-screening the heavy metal resistance strain; and d, detecting the heavy metal removing capability of the strain. According to the present invention, with the detection test on the heavy metal removing capability of the strain obtained by carrying out enrichment acclimatization on the heavy metal resistance strain with the metal ion-containing culture medium and purification, the reasonable and effective screening method for the heavy metal removing strain is established so as to obtain the strain suitable for requirements; and with application of the Pseudomonas aeruginosa ZC6 in the heavy metal pollution treatment, advantages of no secondary pollution, high treatment efficiency, wide application range, low cost and the like are provided.

The invention relates to functions of genes of pseudomonas aeruginosa and an application of the genes, wherein the gene BN889_05221, the gene PA0243, the gene PA3808, the gene PA1993 and the gene PA1115 of pseudomonas aeruginosa are the necessary host genes of phage infection, and are used for screening the relevant medicines for inhibiting the phage infection. According to the invention, through the study on the relevant host genes of phage infection, a molecular mechanism for the interaction between phage and host bacteria can be well understood, therefore, a theoretical basis is provided for the treatment on the phage, meanwhile, new target genes related to virus infection can be found, and assistance is provided for screening antiviral drugs.

The invention relates to the field of disinfection and sterilization, which discloses a method for killing pseudomonas aeruginosa. The method is achieved only by putting a carrier infected with the pseudomonas aeruginosa in plasma environment at a low temperature of between 10 DEG C and 50 DEG C for killing the pseudomonas aeruginosa for 30-100 seconds, wherein the low-temperature plasma environment is generated by a radio frequency plasma discharge device.

The invention discloses a strain of Pseudomonas aeruginosa and application thereof. The preservation number of the strain of Pseudomonas aeruginosa is: CGMCC No.11776. The present invention is a strain of Pseudomonas aeruginosa that efficiently degrades the oomycete fungicide-mancozeb isolated from tobacco root soil. Experiments show that the bacterium can use mancozeb as the only carbon source in LB medium It grows with energy and degrades mancozeb; under the condition of liquid culture with exogenous nutrients, the bacteria can degrade more than 90% of the high concentration of mancozeb mixed in the medium for 48 hours, and It has a good degradation effect in a wide pH range; the bacteria can be used for the biodegradation of mancozeb residues in water and surfaces, making up for the current use of Pseudomonas aeruginosa to degrade mancozeb pesticide residues Technology gap.

A method for the inactivation of Pseudomonas aeruginosa and Sphingomonas paucimobilis based on the growth ring of water supply pipe network, which involves two pathogenic bacteria Pseudomonas aeruginosa and Sphingomonas paucimobilis in drinking water Bacteria inactivation method. It aims to solve the problem of poor inactivation effect of Pseudomonas aeruginosa and Sphingomonas paucimobilis in existing drinking water. Method: Add α‑FeOOH and H2O2 to the clean water tank of the city water supply plant, and the process is completed. The cost of H2O2 in the present invention is low, and the α-FeOOH material is cheap and easy to obtain, and it is the main component of the growth ring. After one addition, it can continue to exist in a large amount in the urban water supply network. In the later stage, only H2O2 needs to be added. The requirements are simple, the energy loss is low, and the input and operating costs are saved. The Fentonoid composed of α‑FeOOH and H2O2 has obvious inactivation effect on Pseudomonas aeruginosa and Sphingomonas paucimobilis present in the filtered water.
