Abstract—A bacterium which had the ability of decoloration on printing and dyeing plant and got the bacteria with strong
Malachite Green was isolated from Zhenjiang printworks and bleaching ability of malachite green. Through preliminary
was identified as Pseudomonas aeruginosa. The effects of identification, we found the optimal conditions for
