Hydrocarbon contamination from industries like petrochemicals threatens the environment and public health. Benzene, toluene, xylene, polycyclic aromatic hydrocarbons in petroleum products are highly toxic. Conventional cleanup methods costly risk secondary pollution. This review highlights biosurfactants, microbially produced compounds that enhance hydrocarbon degradation by lowering surface tension increasing bioavailability. Biosurfactants biodegradable eco-friendly, making them a sustainable alternative to synthetic surfactants. The intends cover biosurfactant sources, types, mechanisms, their applications hydrocarbon-contaminated environments. Recent bioremediation advancements, including microbial-enhanced oil recovery, soil water cleanup, heavy metal removal, discussed. Optimizing production is also explored, offering green effective solution combat promote environmental restoration.

Oil spills occur during different operations in the energy sector, such as crude oil transport, tank filling and cleaning, fueling. Such are one of major causes accumulation derivatives environment, requiring remediation soil marine environments. The production a biosurfactant by Starmerella bombicola ATCC 222214 was maximized investigating effect carbon/nitrogen sources culture conditions. mineral medium selected for its supplemented with 2.0% potato peel flour, 5.0% waste canola frying oil, 0.20% urea. conditions were 200 rpm shaking speed, fermentation time 180 h, 4.0% inoculum size. yield isolated 7.72 g/L. emulsification rates heavy motor 65.55 95.00%, respectively, indicating an affinity complex hydrocarbons. In stability tests performed at pH values, temperatures, NaCl concentrations, surface tension ranged from 27.14 to 31.08 mN/m. critical micelle concentration 2.0 g/L, which 33.26 composed 6,6-dimethoxy-octanoic acid azelaic acid, it exhibited low toxicity Brassica oleracea Solanum lycopersicum. kinetic test, allowed removal 82.30%, 96.65%, 98.25% exhaust sand, silty soil, clay while static test packed columns, yields 66.62%, 63.03%, 58.45%, respectively. produced this study is promising environmental applications sector.

Enterococcus faecalis is a significant pathogen in healthcare settings and frequently resistant to multiple antibiotics. This resistance compounded by its ability form biofilms, dense bacterial communities that are challenging eliminate via standard antibiotic therapies. As such, targeting biofilm formation considered viable strategy for addressing these infections. study assessed the effectiveness of surfactin, cyclic lipopeptide biosurfactant synthesized Bacillus subtilis natto NTU-18, preventing E. faecalis. Analytical characterization surfactin was performed liquid chromatography‒mass spectrometry (LC‒MS). Additionally, transcriptomic sequencing quantitative PCR (qPCR) were used investigate alterations gene expression following treatment with surfactin. The data revealed notable suppression crucial virulence-related genes responsible pilus construction exopolysaccharide synthesis, both which vital adhesion structure. Functional tests confirmed substantially reduced attachment Caco-2 cell monolayers curtailed production. Moreover, confocal laser scanning microscopy thinning biofilms. These observations support potential utility as therapeutic agent manage biofilm-associated infections caused
