Application

Sodium 2-bromoethanesulfonate(BES) was used to investigate the effect of BES on inhibition of bacterial growth.

General description

Sodium 2-bromoethanesulfonate acts as methanogenesis inhibitor during anaerobic digestion. It reacts with lithium sulfinated polysulfones(PSU) to yield sulfoethylated PSU.

Sites in the West Siberian peat bog 'Bakchar' were acidic (pH 4.2-4.8), low in nutrients, and emitted CH4 at rates of 0.2-1.5 mmol m(-2) h(-1). The vertical profile of delta13CH4 and delta13CO2 dissolved in the porewater indicated increasing isotope fractionation

The conversion routes of carbon monoxide (CO) at 55 degrees C by full-scale grown anaerobic sludges treating paper mill and distillery wastewater were elucidated. Inhibition experiments with 2-bromoethanesulfonate (BES) and vancomycin showed that CO conversion was performed by a hydrogenogenic

Nano zero valent iron (NZVI), although being increasingly used for environmental remediation, has potential negative impact on methanogenesis in anaerobic digestion. In this study, NZVI (average size = 55 ± 11 nm) showed inhibition of methanogenesis due to its disruption

In this study, the microbial response of anaerobic sludge digestion to the addition of two classic methanogenic inhibitors (chloroform, 2-bromoethanesulfonate) was investigated. Both the toxicants showed their effectiveness on CH(4) production, whereas the hydrogen responses and acetate accumulations were elicited

Treatment of anaerobic granules with heat and two chemical treatments, contacting with 2-bromoethanesulfonate (BES) and with BES + Chloroform, were applied to suppress hydrogen-consuming microorganisms. Three mesophilic expanded granular sludge bed (EGSB) reactors-R(Heat), R(BES), and R(BES + Chlo)--were inoculated with
