Abstract

The invention belongs to the technical field of biological treatment of environmental inorganic pollutants, and particularly relates to an Enterobacter bugandensis CH6 capable of prevent and control enrichment of Cd and Pb in leafy vegetables, and a use thereof. The Enterobacter bugandensis CH6 capable of prevent and control enrichment of Cd and Pb in leafy vegetables is classified as Enterobacterbugandensis CH6, and the preservation number is CCTCC M 2019421. The strain, Enterobacter bugandensis CH6, has the function of fixing heavy metals and promoting plant growth.

Description

technical field [0001] The invention belongs to the technical field of biological treatment of environmental inorganic pollutants, and in particular relates to a strain of Enterobacter bugunii CH6 capable of preventing and controlling the enrichment of Cd and Pb in leafy vegetables and its application. Background technique [0002] With the rapid development of industrialization and urbanization, the massive discharge and improper disposal of pollutants such as mining areas and agricultural wastes have led to increasingly prominent environmental problems such as heavy metal accumulation and exceeding standards in vegetable fields in many areas of our country, which has aroused great concern from all walks of life. According to the "National Soil Pollution Survey Bulletin" in 2014, the total point exceeding standard rate of contaminated soil in my country is 16.1%, among which Cd has the highest exceeding standard rate, reaching 7.0%. Inorganic heavy metal pollutants, such as...
