Gas production enterobacteria and uses thereof

Abstract

The invention discloses an enterobacteria aerogenes and the application. The inventor screens Enterobacter aerogenes XM02 by a great deal of experimental researches. The bacterial has ferrum redactum active, facultative and electron donor, which can survive in the aerobic or anaerobic environment, wherein the electron donor in the anaerobic environment has the wide application, the electron donor which can electron donor comprises glycerin, citrate, dextrose, sucrose or the like, the ferric iron which can deacidize comprises szomolnokite, goethite, lepidocrocite, bloodstone, yellow copiapite or the like.

Description

technical field

[0001] The invention relates to the technical field of screening new strains, in particular to an Enterobacter aerogenes and its application. Background technique

[0002] The average content of iron in the earth's crust is 5.6%, which is the second most abundant metal in the earth's crust. Iron usually exists in the form of insoluble Fe(III) oxides in the natural environment. The reduction of iron is an enzymatic reaction mediated by specific microorganisms. Bacteria with iron reduction ability are the driving force for the reduction of iron oxides. Studies have shown that iron reduction not only affects the biogeochemical cycle of iron, but also participates in a variety of soil environmental processes, including: soil gleization process, migration of nutrients (such as P, K, Ca, Mg, etc.) and trace metal elements release, anaerobic degradation of organic pollutants, reductive detoxification of metals, and suppression of methane emissions, etc., have broad...
