Abstract:
A salt-tolerant strain GYW capable of decolorating azo dye was isolated and identified as Halo-monas sp.by 16S rDNA.The result showed that the decolorizing salt-tolerant bacteria could survive above the 10% salt concentration and it could decolorize many dyes.The strain had a high decolorizing rate on acid red GR under the condition of pH 7.5,anaerobic 30?C and 10% NaCl.The ion of Cl- strong inhibited the decolorization of acid red GR,and the ion of SO42- affected little on the decolorization,and the lycine addi-tion with the optimal concentration of 200 mg/L could enhanced the decolorization rate under high NaCl concentration.
