The natural environment is often contaminated with hydrophobic pollutants such as long-chain hydrocarbons, petrochemicals, oil spills, pesticides, and heavy metals. Hydrophobic a toxic nature, slow degradation rates, low solubility pose serious threats to the human health. Decontamination based on conventional chemical surfactants has been found be toxic, thereby limiting its application in pharmaceutical cosmetic industries. In contrast, biosurfactants synthesized by various microbial species have considered superior counterparts due their non-toxic economical nature. Some can withstand wide range of fluctuations temperature pH. Recently, emerged innovative biomolecules not only for solubilization but also biodegradation environmental metals, petroleum spills. Biosurfactants well documented function emulsifiers, dispersion stabilizers, wetting agents. amphiphilic nature potential enhance hydrocarbons spills reducing interfacial surface tension after distribution two immiscible surfaces. However, remediation contaminants using affected considerably temperature, pH, media composition, stirring rate, microorganisms selected biosurfactant production. present review briefly discussed current advancements microbially biosurfactants, factors affecting production, addition, latest aspect circular bioeconomy terms generating from waste global economic aspects

A reactive electrochemical membrane (REM) has been identified as an excellent platform in micropolluted water purification due to its rapid mass transfer capability. Unlike traditional flow-by systems, the convection-enhanced REM systems activate REM's inner reaction sites, potentially imparting a spatially variable reactivity. Therefore, we explored spatial scale of micropollutant oxidation REM. Theoretical and experimental evidence demonstrated that might feature nonuniform activity along depth (about hundreds micrometers). That is, zone generating •OH was located within few micrometers beneath surface, i.e., less than 1% overpotential/potential drop The character render strong direct electron ability, enabling removal electron-rich micropollutants even at low potentials. However, unsatisfactory electron-poor observed, higher potential required prompt generation •OH. These results provide in-depth insight into REM, contributing analysis mechanisms optimization design operation modules for cost-effective purification.
