“…Microbial surfactants have numerous properties, including temperature stability, pH, salinity stability, biodegradability, low toxicity and high foaming potential, which make them promising in many processing applications [18]. Biosurfactants are divided into five categories: phospholipids glycolipids, lipopeptides, neutral lipids, and polymeric substances [19,20].…”

One promising bacterial strain (B3), biosurfactant. Alkyl acrylate-vinyl acetate copolymer was prepared using varying lengths effect of copolymer additives along with biosurfactant on the crude oil wax crystallization meth point test and viscosity index measurement for gas oil. polymeric molecule. The application of only c point of gas oil by 3 and 9 o C respectively. Furthermore, the same copolymer along with biosurfactant decreased the solid point of gas oil by 15 and 21 o C, respectively. might be used to slow the formation of wax crystals and shape shorter crystals. Because of this shift in crystal form, wax crystals' capacity to intergrow and interlock is substantially reduced. By increasing the length of the alkyl chain and mi the copolymer and biosurfactant, the viscosity index of gas oil was raise a better viscosity index modifier at all concentrations in gas oil.

Biodegradable polymers (e.g. poly(butylene succinate)-PBS) have been used in several sectors such as the environmental area, especially in bioremediation, in biological processes for conversion of pollutants into inorganic compounds. In this study, the foresight methodology for the use of biodegradable polymers, including PBS, reveals a publication rate of approximately 8.74 articles and 30.63 patents per year, between 2005 and 2019. However, the application of PBS, specifically, is still restricted to the environmental area, with only 3.0% of the 1484 works from this period. The results showed a more significant number of papers on the PBS application for synthesis, characterization, and application in the areas of Chemistry, Physics, and Pharmacy. In the area of bioremediation, only three studies related to PBS were found, revealing the lack of research and development to increase the contribution in the area of environmental recovery.

“…The sorption capacity and selectivity of sawdust can be improved by increasing the surface hydrophobicity. Ismail et al [32][33] obtained an effective sorbent for oil spill cleanup by esterification of sawdust with oleic acid. Hussein et al [34] improved the sorption capacity of acid treated sawdust to 4.82 g/g.…”

Oily brine from the gas and oil industries remains the most difficult wastewater to treat due to its complex chemical composition, which includes aromatic hydrocarbons. Even at low concentrations, the presence of BTX (benzene, toluene, xylenes) can be extremely harmful to aquatic ecosystems. Fixed-bed adsorption columns are recommended for oily water treatment due to their flexibility and easy operation. In this research, pine sawdust modified with polydimethysiloxane (PDMS) and hydrophobic nanosilica was applied as a sorbent in a filtration system. The surface modification of raw fiber allowed to change its morphology and increase the roughness of it. The Yoon-Nelson, Bohart-Adams, Clark, and Belter models were applied to simulate continuous biosorption. The Bohart-Adams model strongly correlated with the experimental data and described the whole dynamic behavior of the column. The effect of feed flow rate (10-50 mL/min) on breakthrough characteristics was determined. Both the breakthrough and saturation time decreased as the flow rate increased. This study indicated that hydrophobized pine sawdust is an effective low-cost potential biosorbent for the removal of BTX fraction from produced water in continuous column mode.
