Production and functional stability of the biourfactant isolated from Stenotrophomonas maltophilia UCP 1601

The present study investigated the production of biosurfactant by Stenotrophomonas maltophilia UCP 1601under submerse fermentation using renewable substrates as carbon and nitrogen sources applying two statistical tools Plakket-Burman experimental design full factorial to optimize bioprocess. A partial characterization was performed measuring surface tension, emulsification index, determination CMC, ionic charge. tested different conditions temperature, pH salinity, in order evaluate stability biomolecule. tension produced corn steep liquor glycerol 27 mN/m, whose yield 12.6 g/L, its character is anionic. critical micelle concentration (CMC) 70% cell-free metabolic liquid. able emulsify 56% burned engine oil. biomolecule showed high functional performance under extreme thermal, saline concentrations stability. All determinations carried out confirm generation a stable, efficient bioproduct that contributes circular bioeconomy great potential for remediation harsh environmental conditions.
