Heat resistance to decompose triphenylmethane dye (Enterobacter cloacae)

摘要

Heat resistant Enterobacter cloacae M82 was isolated from the dyed wastewater. The optimum decolorizing ability for the carbon source Raphinose, lactose, mannitol, glucose and nitrogen source was investigated in 0.3% glucos and 0.1% yeast extract The highest decolorization activity at pH 5 and 40 ° C was observed at pH 5 and 40 ° C. The rate of decolorization of triphenylmethane dye by Enterobacter cloacae was 99%, which is much higher than that of conventional strains. Proved to be a very excellent strain.
