Combinational Decolorization of Simulated Malachite Green Polluted Water by Plant and Microbe

This article dealt with the synergistic effect of plant and microbe on malachite green decolorization. Plant ( Canna generalis ) and microbe ( Pseudomonas aeruginosa ) were adapted to culture in 20 mg.L -1 malachite green solution alone or combined for 7 d or 14 d,after culture the residual concentration of the malachite green solution were determined. The results indicated that P. aeruginosa used alone was useless to malachite green decolorization, while C. generalis used alone removed 42.6%-53.2% of malachite green in 7 d-14 d culture, and the combined use of C.generalis and P.aeruginosa removed 60.4%-75.5% of malachite green. P.aeruginosa and C.generalis had synergistic effects on malachite decolorization. This research was benifited for the actual use of combinational remediation of malachite green by plant and microbe.
