Microalgal interstrains differences in algal-bacterial biofloc formation during liquid digestate treatment.

abstract：:Activated sludge is widely used to treat industrial wastewater, but its efficiency is affected by a variety of factors, including toxic substances such as tetrahydrofuran (THF). In this study, we examined the toxicity of THF at different concentrations (0-320 mM) on the microbial community in activated sludge. A remar...
