Naturally present aquatic microorganisms play an important role in water purification systems, such as the self-purification of surface waters. In this study, two sources representing polluted (Olympic Green; OG) and unpolluted (Jingmi river; JM), were used to explore by bacteria under different environmental conditions. The dominant bacterial community OG JM waters (both are Firmicutes Proteob...

Microbially derived extracellular polymeric substances (EPSs) occupy a large portion of dissolved organic matter (DOM) in surface waters, but the understanding photochemical behaviors EPS is still very limited. In this study, characteristics from different microbial sources (Shewanella oneidensis, Escherichia coli, and sewage sludge flocs) were investigated terms production reactive species (RS...

Extracellular polymeric substances (EPS) production and composition for Salmonella pullorum SA 1685 exposed to artificial groundwater (AGW) has been examined utilizing three EPS extraction methods: lyophilization, ethanol, and sonication. Experiments were carried out to evaluate the robustness of three EPS extraction methods and the sensitivity of each to subtle changes in solution ionic streng...
