Summary: Sophorolipids are surface-active glycolipids produced by non-pathogenic yeast species and have extensive industrial applications due to their unique physicochemical properties. Compared to chemically synthesized surfactants, sophorolipids are less toxic, more environmentally friendly, biodegradable, and exhibit robustness for industrial applications. They also possess low critical micelle concentrations, reduced interfacial surface tension, and the ability to dissolve non-polar components. The article highlights the utilization of these properties, discusses the advantages and disadvantages of sophorolipids, and explores their potential commercial applications in real-world scenarios. The review also compares biosurfactants with man-made equivalents and provides insights for manufacturing natural or green surfactants with innovative qualities.

Summary: Microbial biosurfactants are highly valuable and chemically stable compounds that have been widely used in the resolution of environmental problems, particularly in the bioremediation of recalcitrant pollutants. These biosurfactants function by reducing surface tension and facilitating emulsification and solubilization of pollutants. Recent research has focused on producing biosurfactants using alternative substrates in a circular economy context.

Summary: The increased industrialization and rapid demand for petroleum and its products have led to environmental contamination through accidental oil spills, industrial runoff, and leakage of underground tanks and pipelines. Petroleum hydrocarbons, considered carcinogenic, neurotoxic, and endocrine-disrupting agents, pose a severe threat to the food chain. Various management strategies have been proposed, but they are mostly expensive and ineffective. The use of microbial glycolipid biosurfactant-assisted remediation strategy is considered a promising approach.

Summary: This study utilized an Anoxic Packed Bed Biofilm Reactor (AnPBR) inoculated with biosurfactant-producing bacteria for the biodegradation of petroleum wastewater. The results showed that highly acclimated biomass decreased the start-up phase period, and increasing initial TPH concentration resulted in higher removal efficiencies. Additionally, decreasing HRT led to an increase in specific hydrocarbon utilization rate.

Summary: This research characterizes the relationships between different input PPU voltages of a micro cathode arc thruster and the plume shape, arc characteristics, thruster propulsion performance, and working fluid ionization. The results show that the change in energy input affects the plume contraction, arc duration, ionization rate, and propulsion efficiency. The degree of plume contraction primarily affects propulsion efficiency in high input voltage state, while arc ionization rate primarily affects thrust-to-power ratio in low input voltage state.
