Effect of different plants on azo-dye wastewater bio-decolorization

摘要：

　　Two salt-tolerant plants (Medicago sativa L.and Sesbania cannabina Pers) as well as a kind of salt-tolerant azo-dye decolorization bacteria GTY (Gracilibacillus sp.GTY) were selected to treat acid red B or acid scarlet GR contaminated water.Results showed that Medicago sativa L.was more tolerant to the azo dyes and more helpful in promoting the azo-dye wastewater bio-decoloration than Sesbania cannabina Pers,but GTY density was higher in the root exudates of Sesbania cannabina Pers than that ofMedicago sativa L.This indicated that the increase of GTY density only partially presented the azo-dye decolorization promoted by plants.
