Changes in Bacterial Community Structure in Wastewaters in the presence of Saccharomyces Cerevisiae and Benzalkonium Chloride

Abstract The benefit of bioaugmentation activated sludge (AS) with yeasts was tested using AS and wastewaters (WW) that originated from the chemical industry, as well synthetic WW. A stimulating effect Saccharomyces cerevisiae on microbial respiration intensity in shown. added yeast biomass maintained viability AS, an inhibitory BAC Bacilli found; however, addition to reduced this effect.
