Influence of carbon sources and C/N ratio on EPS production in anaerobic sequencing batch biofilm reactors for wastewater treatment

Characterization and removal of dissolved organic matter in a vertical flow constructed wetland

“…It is reported that DOM would be transformed during the wastewater treatment processes and most of the DOM in treated effluent is found in soluble fraction (Shon et al, 2006). The properties of DOM left in sewage effluent during the traditional biological treatment processes are influenced by the wastewater sources (Guo et al, 2012;Miqueleto et al, 2010), solid retention times (Al-Halbouni et al, 2008;Jarusutthirak and Amy, 2007) and hydraulic retention times (Langenhoff et al, 2000). However, until recently, there have been very few reports characterizing DOM in vertical flow constructed wetlands.…”

Extracellular polysaccharide (EPS) production by a novel strain of yeast-like fungus Aureobasidium pullulans

“…EPS are also thought to promote cell-cell recognition/communication and protect cells against harsh environmental conditions. Different carbon sources and the carbon/nitrogen ratio (C/N) can also influence the production and composition of EPS (Miqueletoa, Dolosica, Pozzia, Forestia, & Zaiat, 2010).…”

Anaerobic treatment of municipal wastewater in a UASB-Digester system : temperature effect on system performance, hydrolysis and methanogenesis

“…As can be seen from Fig.3.1c, after adding cosubstrate, suspended sewage COD removal efficiency maintained stable in period 2 and started to increase at the beginning of period 3. This increase may be explained by a higher extracellular polymer substances (EPS) production in the digester caused by adding glucose (Miqueleto et al, 2010;Miqueleto et al, 2005), though this was not verified in this study. In the UASB reactor, a higher EPS content may contribute to better suspended solids capture in the sludge bed.…”
