Biodegradation and removal of 3,4-dichloroaniline by Chlorella pyrenoidosa based on liquid chromatography-electrospray ionization-mass spectrometry
3,4-Dichloroaniline (3,4-DCA), widely used in the synthesis of dyes, textile and herbicides, is toxic to living organisms. The purpose of this study was to investigate the capability of green algae in degrading and removing 3,4-DCA in water. An environmentally ubiquitous green alga Chlorella pyrenoidosa was isolated from fresh aquatic environment. Then unicellular alga was incubated with 3,4-DCA at a concentration of 4. 6 μg/ mL in water. The residual concentration of 3,4-DCA in the medium and the metabolites were analyzed. A removal percentage of 78. 4 % was obtained over a 7-day period. Two major metabolites with less toxicity were identified as 3,4-dichloroformanilide and 3,4-dichloroacetanilide from the liquid chromatography-electrospray ionization-mass spectrometry analysis. The application of microalga C. pyrenoidosa may have potential for removing the environmental pollutant in aquatic environment. © 2012 Springer-Verlag.
