Introduction: This study assesses the environmental impacts of mannosylerythritol lipids (MELs) production for process optimization using life cycle assessment (LCA). MELs are glycolipid-type microbial biosurfactants with many possible applications based on their surface-active properties. They generally produced by fungi from family Ustilaginaceae via fermentation in aerated bioreactors. The aim our work is to accompany development biotechnological products at an early stage enable environmentally sustainable optimization. Methods: done identifying hotspots and potentials improvement a reliable quantification impacts. processes evaluated cradle-to-gate approach Environmental Footprint (EF) 3.1 impact method. LCA model upscaled experimental data purification, assuming 10 m³ scale. In case analyzed, rapeseed oil glucose, purified separation, solvent extraction, chromatography. Results: results show that provision substrates major source accounts 20% Climate Change more than 70% categories Acidification Eutrophication. Moreover, 33% caused energy requirements aeration bioreactor, while purification 42% respectively. For solvents identified as main contributors most categories. Discussion: illustrate reduce substrate requirements, enhanced bioreactor aeration, efficient use downstream processing. By scenario analysis, considering both adaptations prospective variations process, laboratory can be supported further findings hence efficiently optimized towards sustainability. presentation kinetic over duration shows novel way calculating visualizing corresponds thinking engineers established indicators detailed system analysis. Altogether, this supports demonstrates potential improvements friendly surfactants.

Waste cooking oils (WCOs) are generated globally from households, the hospitality industry, and other sectors. Presently, WCOs mainly employed as feedstock for biodiesel energy production, strongly depending on availability of WCOs, which often imported countries. The objective this review is to give an overall comprehensive panorama impacts, regulations, restrictions affecting their possible uses producing high-value products, such bio lubricants, surfactants, polymer additives, road construction solvents. Interestingly, many reviews reported in literature that address use but a topic missing. Published studies, industry reports, regulatory documents were examined identify trends, challenges, production statistics, environmental current production. data collected show hold immense potential renewable resources sustainable industrial applications line with global carbon neutrality goals circular economy principles. However, achieving shift requires addressing gaps, enhancing collection systems, optimizing conversion technologies. This underlines need collaborative efforts among policymakers, stakeholders, researchers maximize contribute development.

A novel, cost-effective, partially purified biosurfactant in the form of a rhamnolipid biocomplex (RLBC) was investigated for its emulsifying properties. The RLBC obtained through cultivation Pseudomonas sp. SP-17 on glycerol, followed by acidic precipitation, without use organic solvents isolation or purification. Composed rhamnolipids (RLs) and exopolysaccharide alginate, exhibited properties towards rapeseed oil comparable to those RLs at concentrations as low 0.15% (w/w), sufficient effective stabilisation oil-in-water (o/w) high internal phase emulsions (HIPEs, 80% oil). Dynamic light scattering analysis revealed similar droplet sizes (9.54 ± 0.96 µm vs. 8.93 0.58 RLs), while multiple confirmed emulsion stability over 120 days. displayed shear-thinning behaviour, with yield stresses approximately 11.5 Pa 7.7 systems prepared RLs, respectively, after seven days pre-storage. Although increasing concentration from 1% (w/w) slightly improved degree dispersion, it did not substantially impact long-term observed lowest concentration. Biodegradation tests demonstrated that preparations are environmentally friendly alternatives synthetic surfactants, achieving 60% biodegradation within 2.5 complete 14 days, which outperformed emulsifiers. offers both environmental economic advantages including reduced production costs elimination solvents. Our findings highlight potential stabilising HIPEs applications requiring sustainable biodegradable formulations, such cosmetics, lubricants, industrial fluids widely manufactured utilised today.

Biosurfactants are considered to be desirable alternatives synthetic surfactants. Sophorolipids produced by nonpathogenic yeast strains one of the main types glycolipid biosurfactants and have various applications. In this work, aqueous phase behavior glycolipid-based biosurfactant sophorolipids (SL) was investigated using polarized microscopy, small-angle X-ray diffraction (SAXS), nuclear magnetic deuterium spectroscopy (2H NMR), transmission electron microscopy (TEM), freeze-etched (FF-TEM), dynamic light scattering (DLS). The binary diagram SL/H2O system constructed, a liquid crystalline cubic constructed micelles observed. A micellar at low concentrations (<50 wt %) found. As concentration increases, after transition phase, it is strictly up 70 %. an isotropic, highly viscous crystal composed three-dimensionally ordered arrangements spherical micelles, which arranged in simple (CubI/Pm3m) or body-centered (CubI/Im3m). rheological properties different temperatures were studied. viscoelastic, viscosity tends decrease uniformly with increasing (15-90 °C) then returns its original state cooling, indicating that possesses satisfactory reversibility high temperature. results expected instructive for application sophorolipids.
