Detail

EPS foam
Extracellular polymers (Extracellular Polymeric, Substances, EPS), it is under certain conditions by microorganisms, mainly bacteria, some polymer secretion in vitro. The main components and microbial intracellular components are similar, some high molecular substances, such as polysaccharides, proteins and nucleic acid polymers. EPS exists widely in activated sludge floc and on the surface, which has important physiological functions, can be environmental nutrients enrichment, into small molecules through the extracellular enzyme degradation after absorbed into cells, can also resist the fungicides and toxic substances harmful to cells.
