Isolation and Immobilization of Bacteria for Decoloring of Dying Wastewater
染料脱色菌的筛选及固定化脱色试验

Seven strains were isolated from the drainage of wastewater treatment plant of a textile factory. Each of these strains candecolor different dye in dye containing water.For example, Pse 4 and Pse29 could decolor more than 80% of the dye Basic Red 13 and the Reactive Red respectively in 12 days when 10mg/L dye in solution was used as sole source of carbon and energy for bacteria. These two strains belong to Pseudomonas.There were no conjunctive function when 7 strains were simply mixed for decolor of mixed dyes in water.However, these strains seem to cooperate effectively when they were immobilized on Attapulgus or plastic rings. Immobilized microbe on Attapulgus candecolor 91% of 60mg/L mixed dyes in 6h. It is supposed to be a good immobilization technology for practical use.
