Abstract

The invention specifically discloses Pseudomonas aeruginosa and application thereof. The accession number of the Pseudomonas aeruginosa is CGMCC No. 10844. The invention also discloses a microbial agent containing the Pseudomonas aeruginosa and a method for passivation of lead. The Pseudomonas aeruginosa provided by the invention has strong capability in passivation of lead in a water body, can finish passivation of lead within 4 to 5 h and has a maximal lead removal rate of 97.33%. As soil contaminated by lead is inoculated with the Pseudomonas aeruginosa, the dehydrogenase activity of the soil can be obviously improved, and lead can be effectively changed into a stable state from a transformable state so as to achieve the effect of lead passivation. Moreover, as the Pseudomonas aeruginosa is used for lead passivation, operation is simple, a period is short, secondary pollution is not posed and high economic benefits and social benefits are obtained.

Description

technical field

[0001] The invention relates to a strain of Pseudomonas aeruginosa, in particular to a strain of Pseudomonas aeruginosa with the function of passivating lead and its bacterial agent, and their application in passivating lead. Background technique

[0002] At present, the heavy metal pollution of domestic soil is very serious, 16% of the soil is poisoned by heavy metals to varying degrees, and tens of millions of tons of grain are lost every year, which seriously endangers production, life and human health. In recent years, lead poisoning incidents have occurred frequently, especially a series of incidents of children's blood lead exceeding the standard have aroused great concern and extensive discussion in China. Because lead exists widely in the environment, after entering the human body through the respiratory tract and digestive tract, it will cause a series of abnormalities in the nervous system, blood system and digestive system of the body, seriously af...
