Removal and metabolism of triclosan by three different microalgal species in aquatic environment.
J Hazard Mater. 2018 Jan 15; 342:643-650.JH

Abstract

Triclosan, an antimicrobial additive widely used in personal care products, has caused the contamination of various aquatic environment. Biodegradation was proved to play a vital role in the treatment of triclosan in wastewater. However, there is limited information about the metabolic pathway. In this study, three common freshwater microalgae including Chlorella pyrenoidosa (C. pyrenoidosa), Desmodesmus sp., and Scenedesmus obliquus (S. obliquus) were applied to remove and biodegrade triclosan in aqueous culture medium. High removal rate up to 99.7% was observed during the treatment of 400μgL-1 triclosan by the three microalgae for 1day. The removal of triclosan attributed to cellular uptake by C. pyrenoidosa, and biotransformation by Desmodesmus sp. and S. obliquus. Simultaneously, triclosan metabolites resulted from hydroxylation, reductive dechlorination, or ether bond cleavage and their conjugates produced through glucosylation and/or methylation were detected in the biodegradation samples. Metabolic pathway of triclosan by algae were firstly proposed in this work, shedding light on the environmental fate of triclosan.
