摘　　要：从化工厂污泥中分离到 4个对蒽醌染料中间体溴氨酸有显著降解和脱色作用的菌株。经鉴定 ,4株菌均为假单胞菌属 (Pseudomonassp )。脱色效果最好的N1菌株能以溴氨酸为唯一碳源生长 ,其脱色效果受温度和 pH影响较大 ,最佳生长条件是 30℃ ,pH7 2。Four strains, capable of degrading and decolorizing bromamine acid, an intermediate of anthraquinone dye, were isolated from sludge of chemical plant The four strains were identified as Pseudomonas spp Experimental results show that strain N1 was able to grow on bromamine acid as sole carbon source Decolorizing bromamine acid of the strain N1 was considerably affected by temperature and pH The optimum growth conditions for the strain are 30℃, pH7 2
