摘要:The isolated strain JD-3 from a pilot-scale upflow anaerobic sludge bed (UASB) reactor, was identified as gram negative facultative anaerobic, the strains was Pseudomonas aeruginosa. It could degrade 100 mg/L of several dyes within 72 h. It had the highest cell growth rate under aerobic conditions, while the decoloration rate was better under anoxic. Different structure was the main reason induced different microbial decolorization rate.
