Problems solved by technology

According to research, various microorganisms reduce As(V) as a way of arsenic tolerance, but when arsenic-tolerant microorganisms reduce As(V) to As(III), the release of As(III) into the groundwater environment is increased. Therefore, exploring the influencing factors of the ability of arsenic-resistant microorganisms to reduce As(V) can provide a theoretical basis for the targeted regulation of influencing factors for the prevention and control of arsenic pollution by microbial methods

Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The embodiment of the present invention provides a strain of bacillus that can efficiently reduce arsenic in anaerobic manner. The bacillus is preserved in China Center for Type Culture Collection, preservation time: June 29, 2018, address of preservation unit: Wuhan University, Wuhan, China , China Center for Type Culture Collection, the collection number is CCTCC NO: M2018411, a strain of the genus Bacillus, named Bacillus sp.XZM.

[0018] Bacillus grows on LB medium, and the colony is round, light yellow, with neat edges and a diameter of 1-3mm.

[0019] Cultivation of Bacillus sp.XZM: Prepare 100 ml of fresh anaerobic LB medium (g / L): 5 g of yeast extract, 10 g of peptone, and 5 g of sodium chloride. After sealing the lid, sterilize it in a...

Abstract

The invention discloses a strain of bacillus for highly efficient anaerobic reduction of arsenic. The bacillus is preserved in China Center for Type Culture Collection, and the preservation number is CCTCC NO: M2018411. Under anaerobic culture conditions, Bacillus has high arsenic reducing ability, and the arsenic reducing rate reaches more than 80% in 4 days, which is of great significance for studying the migration and transformation of arsenic.

Description

technical field [0001] The invention relates to the field of environmental microbes, in particular to a bacillus strain for highly efficient anaerobic reduction of arsenic. Background technique [0002] Arsenic exists widely in natural environments such as water and soil, among which hundreds of species exist in the form of arsenic minerals. Arsenic and its compounds are highly toxic, especially arsenic and inorganic arsenic compounds have also been included in the list of carcinogens by the World Health Organization. At present, arsenic-containing compounds are widely used in production activities such as herbicides, insecticides, pesticides and various alloys, but in some areas where groundwater has been drunk for a long time, high-arsenic groundwater has been found to be widely distributed. Groundwater (the mass concentration of arsenic is higher than 0.05mg / L) is the main source of drinking water, and local arsenic poisoning has occurred. In groundwater systems, arseni...
