Abstract
Three different azo dyes such as Fast red metanil yellow and Fast orange were examined for their decolorization by O oeni ML34 Fast red FR was decolorized by 68 whereas the other dyes were removed by only about 30 The effects of glucose addition substrate dye concentration and environmental factors temperature pH on decolorization were investigated by twolevel factorial design The statistical analyses revealed that glucose specifically increases the extent of FR decolorization A glucose level of 5 g/l was the optimum concentration for removal of FR reaching a decolorization percentage of up to 93
