印染废水脱色菌的选育及脱色研究

Selective Culture and Decolorization of Decolorizing Bacteria in Waste Water from Textile Printing

富集筛选出具有良好脱色活性的混合菌A，并从中分离出单菌N和F，以去除印染废水中的红颜色．接种量为1．25％、温度为30℃的静置培养以及pH为7的条件时，以尿素代替蛋白胨作为部分氮源，可降低培养基成本，且脱色率为80％．

The mixed bacteria A with good decolorizing activity were screened by enrichment; and single bacterium N & F among them were isolated.They removed red color in dye waste water. With temperature of 30℃ and pH 7 and 1. 25 % inoculation and static culture as suitable decolorizing conditions,the replacement of peptone by 7. 49 μmol· L-1 urea as part of nitrogen source resulted in a low cost of culture media and a decolorizing efficiency of 80 %.
