“…Due to population growth and recent patterns of consumption, there was an increase in the production of agroindustrial and agricultural systems. A large amount of wastes is generated because of the unproductive increase in productivity, leading to economic, social, and environmental damage [10]. e use of residues as alternative substrates for formulation of culture media to produce bioemulsifiers provides carbohydrate and/or lipid levels required to support microbial growth and bioemulsifier biosynthesis, favoring microorganism growth and metabolite production [11][12][13].…”

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.

Background/ Objectives: Biosurfactants are extracellular surface-active compounds produced by bacteria, fungi and yeast. Interest in biosurfactant has been increasing due to their unique properties. The objective of this study is to screen for potential biosurfactant producing yeasts from mangrove areas of Gujarat in India. Methodology: The biosurfactant producing yeasts isolated from five different mangrove sites i.e. Hazira, Mandroi, Mirzapur, Kantiyajal and Machhad of Surat, Gujarat during summer season of 2015. Isolated yeasts were screened for the production of biosurfactant by Parafilm M, Oil displacement and Emulsification index method in which cottonseed oil was used as a substrate. The type of biosurfactant produced was identified by Phenol-sulfuric acid test, Biuret test and phosphate test. Findings: Total twenty four yeasts were isolated from soils of sampling sites. Yeasts were initially screened by Parafilm M and oil displacement method. Out of these 24 isolate, 6 isolates namely, Ky-48, Ky-53, Ky-54, Ky-84, Ky-86 and Ky-87 showed promising biosurfactant activity. These six isolates were further subjected to secondary screening method: Emulsification test, to identify biosurfactant production. Two isolates, namely Ky-46 (emulsification index: 61.53 %) and Ky-86 (emulsification index: 46.66 %) showed maximum biosurfactant production. All six isolates showed positive result for phenol-sulfuric acid method. This indicated that the isolated biosurfactant was Glycolipid in nature. Novelty/Applications: Few mangrove yeasts have potential to produce high amount of glycolipid that can be used in food processing and detergents, healthcare and cosmetics industries.

There has been considerable interest in the use of biosurfactants due to the diversity of structures and the possibility of production from a variety of substrates. The potential for industrial applications has been growing, as these natural compounds are tolerant to common processing methods and can compete with synthetic surfactants with regards to the capacity to reduce surface and interfacial tensions as well as stabilise emulsions while offering the advantages of biodegradability and low toxicity. Among biosurfactant-producing microorganisms, some yeasts present no risks of toxicity or pathogenicity, making them ideal for use in food formulations. Indeed, the use of these biomolecules in foods has attracted industrial interest due to their properties as emulsifiers and stabilizers of emulsions. Studies have also demonstrated other valuable properties, such as antioxidant and antimicrobial activity, enabling the aggregation of greater value to products and the avoidance of contamination both during and after processing. All these characteristics allow biosurfactants to be used as additives and versatile ingredients for the processing of foods. The present review discusses the potential application of biosurfactants as emulsifying agents in food formulations, such as salad dressing, bread, cakes, cookies, and ice cream. The antioxidant, antimicrobial and anti-adhesive properties of these biomolecules are also discussed, demonstrating the need for further studies to make the use of the natural compounds viable in this expanding sector.
