Summary: This article reviews the classification, uses, and side effects of surfactants in the cosmetic, personal care, and pharmaceutical industries, dividing them into synthetic, bio-based, and microbial biosurfactants. It suggests that industries should consider microbial biosurfactants as a separate category due to their biocompatibility, eco-friendliness, and potential for less toxicity compared to chemical surfactants.

Summary: In this study, bio-based aromatic polyketones (PKs) and polyetherketones (PEKs) were synthesized using electrophilic substitution reaction. The introduction of alkoxy side-chains at the hydroxyl groups of divanillic acid prior to polymerization allowed for the successful synthesis of soluble polymers with determined chemical structures. The PKs exhibited high glass transition temperatures (T-g) and thermal stability compared to the PEKs, highlighting the importance of side-chain structures in determining properties of these materials.

Summary: Surfactin, a promising compound for various industries, has low production yield in wild strains. In this study, the overexpression of eight genes related to fatty acid biosynthesis pathway increased the surfactin yield of engineered strains. The conversion of acetyl-CoA to malonyl-CoA was identified as the rate-limiting step in fatty acid biosynthesis. Additionally, modifications in the surfactin isoforms were observed, indicating the potential for pathway engineering. Deletion of the lpdV gene led to a significant decrease in surfactin production, highlighting the importance of branched-chain fatty acid biosynthesis. This work enables the design of more efficient engineered strains for surfactin production and expands its industrial applications.

Summary: This study investigated the microbial communities and functional groups in production water from five petroleum reservoirs in China using chemical and molecular biological analyses. The dominant phyla in these reservoirs were Proteobacteria, Deferribacterota, Firmicutes, Desulfobacterota, Euryarchaeota, and Thermoplasmatota. The corrosion rates in the production water were higher than controls and were positively correlated with the abundances of sulfate-reducing prokaryotes (SRP). The SRP diversity analysis showed differences between onshore and offshore oilfields, and the core SRP taxa varied based on temperature.

Summary: The adsorption kinetics of surfactin homologues at the n-hexadecane/aqueous solution interface was investigated using droplet-based microfluidic method. Molecular dynamics simulations showed that the adsorption energy of surfactin depends on its structure. Experimental results demonstrated that shorter chain surfactin, such as C13-surfactin and C14-surfactin, had faster adsorption and desorption rate constants. The study also revealed that C15-surfactin had a stronger tendency to adsorb at the interface due to its higher adsorption energy and aggregation behavior in solution.

Summary: In this study, simulations were conducted to investigate the behavior of CO2 and CH4 adsorption and diffusion on kerogen models with different maturity. It was found that CO2 has a higher adsorption capacity compared to CH4, and this capacity increases with maturity. Furthermore, the addition of water reduces the adsorption and diffusion coefficients of both gases but increases the selectivity of CO2 over CH4. These findings suggest that injecting CO2 into shale gas and oil formations can enhance energy recovery.

Summary: This study investigates the effect of air injection on microbial composition and transcriptional activity in oil reservoirs. The researchers found that Firmicutes, specifically the Bacillus genus, were the dominant active bacteria in all samples and their proportion increased with higher gas/liquid ratios. As the gas-to-liquid ratios increased, the microbes showed higher overall transcription activities and propionate became an important metabolite. This research provides theoretical guidance for activating endogenous oil displacement microorganisms and offers insights for the industrial exploitation of depleted reservoirs and extending the development life of oil reservoirs.
