Anaerobic toxicity assay of plasticisers

Global Profiling of Metabolite and Lipid Soluble Microbial Products in Anaerobic Wastewater Reactor Supernatant Using UPLC–MSE

“…Most studies on SMPs focus on their overall properties such as concentration, molecular weight distribution, , aromaticity, , biodegradability, and toxicity . Also, the characterization of SMPs has previously been performed using a number of colorimetric methods, − and HPLC with UV detection. ,,, However, these methods only characterize SMPs at a macro level but do not provide any molecular identification.…”

The production and biotransformational changes of soluble microbial products (SMPs) and its effects on anaerobic wastewater treatment

“…Their toxicity to the methanogenic process was measured by biogas production (Owen et al, 1979) as methane production is an indication of methanogenic activity, which is an important stage in anaerobic processes. Anaerobic toxicity of DEHP had been analysed in several studies, and was proven to inhibit methanogenesis and is toxic at an average concentration of above 100 mg/L; and the purpose for their synthesis was for enhancing the integrity of cell membranes, and also a protective mechanism for some variations of bacterial species (Babu & Wu, 2010;Benotti et al, 2009;Chen, 2004;Gavala et al, 2003b;Oconnor et al, 1989;Trzcinski et al, 2012).…”
