The invention discloses a Streptomyces puniceus strain. LYzhlm for highly efficiently removing hexavalent chromium pollution. The strain is preserved in China General Microbiological Culture Collection Center on December 2, 2015 with the preservation number of CGMCC No.11773, and is named as Streptomyces puniceus strain. LYzhlm. The Streptomyces puniceus strain. LYzhlm has strong hexavalent chromium removal performance, and can reduce hexavalent chromium ions with the concentration of 100-1000 mg/L into chromium with the valence of 0, and the reduction rate is 100%.
Description
technical field [0001] The invention relates to the technical field of microbes, in particular to a strain of streptomyces capable of efficiently removing hexavalent chromium pollution. Background technique [0002] With the rapid development of society and economy, chromium has been widely used in industry, but at the same time it has brought a lot of pollution to the environment. In industry, chromium is widely used in electroplating, wood preservation, leather manufacturing, steel and other industries, and is finally discharged into the environment in the form of waste water and waste residue. According to the data of the Ministry of Environmental Protection, at present, the area of cultivated land polluted by heavy metals such as chromium in my country is nearly 20 million hectares, accounting for about 1 / 5 of the total area of cultivated land. Every year, more than 10 million tons of grain are reduced due to heavy metal pollution across the country. Although chrom...
