چکیده انگلیسی
A strain HXL-2 from a lab-scale sequence batch reactor (SBR) was identified as Candida rugopelliculosa based on its physiological, biochemical characteristics, and 26S rDNA D1/D2 gene phylogenetic analysis. About 90% of the 50 mg/L Reactive blue 13(RB13) was degraded in 48 h after inoculation with strain HXL-2. The optimum efficiency of pH on decolorization was obtained at pH 5.The optimum efficiency temperature of C. rugopelliculosa HXL-2 decolorization RB13 was obtained at 28 °C. The color removal efficiency was obtained at 80.3% when the feed concentration reached 2000 mg/L. We first detected naphthalene-like compound is produced as degradation intermediate after the cleavage of RB13 azo bond, detected 1-chloro-3-aniline- 2,4,6-triazine. We proposed degradation pathway of Reactive blue 13 by Candida sp and proved RB13 degradation pathway by Candida sp. has some difference from RB13 degradation pathway by Pseudomonas sp.
