Abstract

Abstract The toxicity of intermittent chlorination to an attached, filamentous, green alga ( Stigeoclonium subsecundum) was found to be related to the biomass of the alga at the beginning of the bioassay. Minimal resistant biomass (MRB) was a term used to describe the lowest biomass of algae able to survive and continue to grow when subjected to a specific level of chlorine at intervals of 6 h for a period of one week. This ability to survive was due to changes in the morphology of the algal filaments and the algal mat.
