Abstract

Decolorizing characteristics of crystal violet by Enterobacter cloace MG82, which can decolorize rapidly triphenylmethane dyes, were investigated. The higher growth and decolorization activity was shown at big ratio of dissolved oxygen in the medium. The decolorization activity of crystal violet revealed highest at the middle of lag phase. As the concentration of crystal violet was higher, the growth of E. cloacae MG82 and decolorizing activity of crystal violet by this strain were worse. The maximum concentration of crystal violet at which E. cloacae MG82 be able to grow was 375 μM. E. cloacae MG82 was not able to use the crystal violet itself as a sole carbon source. So, it was shown that growth of E. cloacae MG82 and decolorization activity of crystal violet by this strain needed addition of another energy sources except this dye.
