Abstract

Biosurfactants are amphiphilic molecules produced by various microorganisms, with potential applications in different industries or processes. The present study aimed to investigate the potential of food (whey) and industrial (corn extract) by-products to be used as single sources of nutrients for microbial surfactants production by two Pseudomonas strains. The supernatants obtained at the end of the bioprocess were used to form emulsions with heptane, octane, and sunflower oil, in order to determine the emulsification index. Good results were obtained with both Pseudomonas sp., the biggest values of the emulsification index being obtained with Pseudomonas putida ICCF 391 strain, followed by Pseudomonas fluorescens ICCF 392.
Keywords: biosurfactants; Pseudomonas putida; Pseudomonas fluorescens; waste substrates; bioprocess biosurfactants; Pseudomonas putida; Pseudomonas fluorescens; waste substrates; bioprocess
