Upconversion phosphors (UCPs) can convert visible light into luminescence, such as UV, which can regulate the growth of microbes. Based on these fundamentals, the community composition of periphytic biofilms stimulated by UCPs doped with Pr3+-Li+ was proposed to augment the removal of phosphorus (P) and copper (Cu). Results showed that the biofilms with community composition optimized by UCPs doped...
The aim of this work was to study the characteristics and flocculating properties of extracellular polymeric substances (EPS) extracted from periphytic biofilms. The periphytic EPS, with an extracted yield of 491.8mg/g, were mainly composed of hetero-polysaccharides and proteins, and the elements C1s, N1s, and O1s. Polysaccharides represented 53.28% of the periphytic EPS. Proteins constituted 20.26%...
