Iron reducing flora and application thereof

The invention relates to an iron reducing flora and application thereof.According to the iron reducing flora, contaminated soil is used as source soil screened by strains, enrichment culture is conducted through an iron citrate culture medium, finally, the iron reducing flora is obtained, and the iron reducing flora mainly comprises, on the genus level, Enterobacter, Shewanella, Acinetobacter, Petrimonas and Aeromonas. The iron reducing flora is applied to phosphorus removal, Fe (III) is reduced in an iron citrate culture medium, blue iron ore can be rapidly synthesized within 1-2 days, and efficient removal of phosphorus in a water body is achieved. 本发明为一种铁还原菌群及其应用，该铁还原菌群利用污染土壤为菌株筛选的源土壤，采用柠檬酸铁培养基进行富集培养，最终获得铁还原菌群，所述铁还原菌群在属水平上的组成主要包括Enterobacter、Shewanella、Acinetobacter、Petrimonas、Aeromonas。所述铁还原菌群应用在除磷中，在柠檬酸铁培养基中还原Fe(III)，在1-2天内能快速合成蓝铁矿，实现对水体中磷的高效去除。
