Abstract

The invention relates to a new application of Acidovorax LS-1, and a kit for repairing arsenic pollution, and applications thereof. The new application is the application of the Acidovorax LS-1 in repairing of arsenic pollution, wherein the Acidovorax LS-1 is added to an arsenic pollutant under anaerobic conditions to reduce pentavalent arsenic into trivalent arsenic, and the Acidovorax LS-1 has apreservation number of CGMCC NO: 11555. According to the present invention, the research results show that the Acidovorax LS-1 can reduce pentavalent arsenic into trivalent arsenic under anaerobic conditions, wherein the bioavailability and the mobility of the trivalent arsenic are much higher than the bioavailability and the mobility of the pentavalent arsenic, such that the activity of arsenicin the environment can be improved through the treatment so as to easily clear or reutilize the trivalent arsenic in the subsequent process; and with the application of the Acidovorax LS-1 in treatment of arsenic pollution, the pentavalent arsenic can be reduced into trivalent arsenic so as to be easily absorbed and enriched, such that the application has good application prospect in the repairingof arsenic pollution.

Description

technical field

[0001] The invention relates to the technical field of environmental microorganisms, in particular to a new application of acidovorous bacteria LS-1, a kit for repairing arsenic pollution and the application thereof. Background technique

[0002] Arsenic is a toxic substance that widely exists in soil, water and other natural environments. It not only reduces soil fertility, crop yield and quality, but also causes water pollution. The way people ingest arsenic is mainly through long-term drinking of drinking water contaminated with high concentration of arsenic and eating food containing arsenic. Through the action of the food chain, arsenic will eventually accumulate in the human body and seriously affect human health.

[0003] The remediation technologies adopted for the current situation of arsenic pollution mainly include engineering remediation, physical and chemical remediation and microbial remediation. Due to the simple cultivation of microorganisms,...
