This study investigated the potential of the bacterium Stenotrophomonas maltophilia UCP 1601 to produce a new biomolecule with emulsifying properties by determining the hemolytic activity, obtaining a halo of 9 mm in blood agar. Fermentations were carried out in saline mineral medium supplemented with 10% waste soybean oil (WSO) and different concentrations of glucose, peptone, ZnCl2, and MgSO4, according to a 24 full-factorial design. The results showed that the best results were obtained in condition 6 (medium composed of 4% glucose, 1% peptone, 2.72% ZnCl2, and 2.46% MgSO4), with excellent high emulsification index of 82.74%, using burned motor oil. The emulsifying property of the biomolecule produced was confirmed by the emulsification index of 78.57, 54.07, and 58.62%, using soybean, corn, and diesel oils, respectively, and the stability at different values of pH, temperature, and NaCl concentrations. The yield of the produced bioemulsifier was 2.8 g/L, presenting an anionic character and polymeric nature (37.6% lipids, 28.2% proteins, and 14.7% carbohydrates), confirmed by FTIR. The new bioemulsifier demonstrated promising potential for bioremediation of hydrophobic contaminants in the environment, since it had the ability to reduce the viscosity of WSO and burned motor oil, as well as excellent dispersion capacity of the burned motor oil in water (69.94 cm2 of oil displacement area), and removing 71.7% of this petroleum derivative from sandy soil.

AbstractIn this paper, the emulsifying properties of Tremella fuciformis (TFS) were assessed in comparison with lotus seed (LTS), purple sweet potato (PSPP) and gum arabic (GA) in oil-in-water (O/W) emulsions. Emulsifying properties were evaluated in terms of the emulsifying activity (EA), emulsifying stability, mean droplet size, zeta potential, shear viscosity and freeze-thaw stability of their emulsions. The results revealed that TFS exhibited excellent EA and best emulsifying stability (100 %) after 21 days at 21 °C. When exposure to 100 °C for 20 min, TFS emulsions showed reduced in droplet size, which was superior as compared to LTS, PSPP, and GA. In zeta-potential test, TFS was proved to be more suitable emulsifier as compared with LTS and GA as it had a comparatively larger magnitude. TFS emulsions showed the smallest droplet size at pH 10.0 followed by pH 3.0 and pH 6.5. Non-Newtonian shear-thinning behavior of all four samples remained same at 4.0 % concentration while the apparent viscosity of TFS was the highest among all. The cream index of 4.0 % TFS was also the highest at freeze-thaw cycles. Therefore, the TFS could be used as emulsifier and thickener in food industry.
