Formation of disinfection byproducts from chlor(am)ination of algal organic matter

► Algal EOM and cells were enriched with protein-like and soluble microbial by-product-like matters. ► Algal cells and EOM of Microcystis and Chlorella exhibited a high potential for DBP formation. ► Yields of total DBPs varied with increasing culture age. ► Cellular materials contributed more to DBP formation than EOM. ► Bromine incorporation was higher in HNMs than in THMs and HANs.
