Abstract：
:Aerobic decolorization and degradation of azo dyes by both of suspended growing cells and immobilized cells of a newly isolated yeast strain LH-F1 were investigated in this study. A yeast strain LH-F1 capable of aerobically decolorizing various azo dyes (20mg/L) was identified as Magnusiomyces ingens basing on 26S rDNA analysis. Meanwhile, effects of different parameters on decolorization of Acid Red B by both of suspended growing cells and immobilized cells of strain LH-F1 were investigated. Furthermore, possible degradation pathway of the dye was proposed through analyzing metabolic intermediates using UV-Vis and HPLC-MS methods. As far as it is known, it is the first systematic research on a M. ingens strain which is capable of efficiently decolorizing azo dyes under aerobic condition. Additionally, this work would also provide a potentially useful microbial strain LH-F1 for treatment of industrial wastewaters containing azo dyes.
