The subject of this article is not a “bug,” but rather a highly significant fraction of the mixed liquor which is critical in the flocculation of bacteria. It must be emphasized that there are many (unstable) fractions that make up what we call mixed liquor suspended solids. Bacteria (viable and nonviable) are joined by fractions including inert material, higher life form organisms and exocellular polysaccharide (EPS).
Based on Anthrone testing, it is common for polysaccharide (as carbohydrates) to account for anywhere between 5-20% of the dry weight of the biomass. EPS consists of carbohydrates, DNA and protein. EPS contributes to the
Bug of the Month: Exocellular Polysaccharide and Floc Formation
In this month's wastewater microbiology spotlight, we examine how elevated levels of exocellular polysaccharide may contribute to viscous flocs
