Abstract
An alkalophilic microorganism capable of degrading dyes was developed for the treatment of alkaline dye solution. This strain was identified as Pseudomonas species. Using this microorganism, biological treatment of dye was studied in Erlenmeyer flasks. The characteristics of this microorganism were observed under various incubating-condition such as temperature, pH, nitrogen source, and macronutrients concentration. The removal effciencies of Disperse Red 60 from synthetic wastewater were 33.5 ~ 36.9% at the range of 30 ~ 40℃, and they were 31.1 ~ 36.7% at the range of initial pH 8 ~ pH 10, respectively. The optimal culture medium was found to be 0.25%(w/v) yeast extract, 0.25%(w/v) polypeptone, 0.1%(w/v) KH2PO4, 0.2%(w/v) MgSO4․7H2O, and 1.0%(w/v) Na2CO3. In treatment of various dyes using Erlenmeyer flasks, the removal effciencies of Disperse Blue 87, Disperse Yellow 64, Disperse Red 60, Acid Blue 193, Acid Red 138, and Direct Yellow 23 were found to be 76%, 71%, 58%, 93%, 94%, and 90% respectively after 24hrs reaction of alkalophilic strain Pseudomonas sp. YBE-12.
