Abstract The widespread use and circulation of industrial emulsifiers pose significant health risks, compounded by their limited availability high cost. Consequently, there is growing interest in exploring the potential natural sources, such as microorganisms like yeast, for emulsifier production. In this study, 25 strains Saccharomyces cerevisiae were isolated from 17 distinct local sources. yeasts characterized based on cell shape, size, colony morphology using yeast malt agar, followed morphological, microscopic, biochemical analyzes. Among isolates, AC1 a vinegar starter demonstrated superior bioemulsifier Emulsification efficiency tests revealed that exhibited values 7.1 cm, 0.71 nm, 34.50%, outperforming other isolates. biomass yield was approximately 4.35 g/L. This strain registered gene bank JZT351 (OR115510) after 100% match with S. . Optimal production conditions identified liquid extract peptone dextrose medium, date juice replacing 75% glucose, at pH 5.5, 30°C, 72 h. resulting emulsification activity, index, oil displacement 8.69 0.95 39.7%, respectively. Fourier‐transform infrared spectroscopy (FTIR) compared functional groups those conventional emulsifiers. Molecular characterization confirmed 1H NMR. FTIR spectra bands 3443.28, 2929.34, 1656.559, 1534.09, 807.06, 1656.55 cm −1 At 0.5–5 ppm, signals spectral frequencies corresponded to mannoprotein structure. 58.09% antioxidant activity 10 mg/mL, assessed DPPH scavenging. It showed highest inhibition against Pseudomonas aeruginosa least Candida albicans

Abstract Biocorrosion, or microbiologically influenced corrosion, is a phenomenon where microorganisms deteriorate the metals. While corrosion generally considered undesirable due to its negative impact on integrity and lifespan of materials, significance biocorrosion major problem because it can cause material deterioration, financial losses, environmental issues. Conventional protection techniques frequently use chemicals, which come with risks human health environment. Biosurfactants are surface tension-reducing agents low molecular weight that attract many researchers industrialists their excellent chemical properties stability at extreme temperatures, pH, under alkaline conditions. These compounds reduce tension liquids, leading improved wetting spreading metal surfaces. This help create more uniform protective layer, preventing accumulation corrosive agents. review explores different types biosurfactants, include lipopeptides, glycolipids, phospholipids, etc., how they work prevent corrosion. The investigation biosurfactants in not only addresses concerns but also holds promise for innovation development efficient long-lasting mitigation strategies variety substrates, given growing demand green sustainable technolo gies.
