Identification of microorganisms, dominants in treatment systems removing ethylene glycol from wastewater

Summary

The results of studies on autoselection of biocenosis that oxidizes ethylene glycol are presented. It has been shown that the formation of an ethylene glycol-destructive biocenosis eliminating the use of special strains occurs on the 12th day, reaching process stabilization from 40 to 64 days, depending on the required concentration of ethylene glycol in the effluent. As a result of the microbiological studies, the main ethylene glycol-destructive cultures of the biocenosis were identified: Staphylococcus capitis, Staphylococcus saprophyticus, Pseudomonas putida and Pseudomonas aureofaciens. Herewith, the dominant cultures are the genus Pseudomonas.
