Biosurfactants have garnered increased attention lately due to their superiority of properties over fossil-derived counterparts. While the cost production remains a significant hurdle surpass synthetic surfactants, biosurfactants been anticipated gain larger market share in coming decades. Among these, glycolipids, type low-molecular-weight biosurfactant, stand out for efficacy reducing surface and interfacial tension, which made them highly sought-after various surfactant-related applications. Glycolipids are composed hydrophilic carbohydrate moieties linked hydrophobic fatty acid chains through ester bonds that mainly include rhamnolipids, trehalose lipids, sophorolipids, mannosylerythritol lipids. This review highlights current landscape glycolipids covers specific glycolipid productivity diverse range products found global market. Applications such as bioremediation, food processing, petroleum refining, biomedical uses, increasing agriculture output discussed. Additionally, latest advancements reduction challenges utilizing second-generation feedstocks sustainable also thoroughly examined. Overall, this proposes balance between environmental advantages, economic viability, societal benefits optimized integration secondary biosurfactant production.

Introduction This study examines the optimum conversion of Wuzhishan pig manure by Black Soldier Fly Larvae (BSFL) at various phases development, as well impact gut microbiota on efficiency. Method and results In terms efficiency, BSFL outperformed growing stage (GP) group, with significantly higher survival rates (96.75%), fresh weight (0.23 g), larval rate (19.96%) compared to other groups. Notably, GP group showed significant dry matter reductions (43.27%) improved feed (2.17). Nutritional composition varied, having a lower organic carbon content. High throughput 16S rRNA sequencing revealed unique profiles, exhibiting an excess Lactobacillus Clostridium . Promising cellulose-degrading bacteria in intestines, including Bacillus cereus subtilis , superior cellulose degradation capabilities. The synergy these thermophilic greatly increased BSFL1-10 demonstrated high growth efficiency under specific conditions, remarkable moisture content (71.11%), residual (63.20%), waste reduction (42.28%). Discussion sheds light optimal stages for manure, dynamics, promising bacteria, enhancement through synergistic interactions. These findings hold great potential sustainable management efficient biomass conversion, contributing environmental preservation resource recovery.
