Screening and Determination Degradation Ability of Organic Phosphate-solubilizing Bacteria in Sewage

Abstract

Abstract:

Organophosphorus solid medium was adopted to isolate strains that were capable of solving organophosphorus from sewage.14 strains of organic phosphate-solubilizing bacteria were obtained by purification. The dissolved phosphorus transparency circle could be determined through plate method, and 4 phosphate-solubilizing bacteria were selected to determine quantitative degradation ability by plate method. Phosphate-solubilizing peaking rate of OPB8, OPB17, OPB15, OPB19 strain were 107.9%, 135.1%, 31.8% and 249.2%. Then, the water-soluble phosphorus concentration dropped in the nutrient solution, of which OPB15, OPB19 strain of water-soluble phosphorus concentration in the nutrient solution dropped by 72.2% and 72.2% respectively.

Key words: sewage, organic phosphate-solubilizing bacteria, screening, degradation ability, determination
