Abstract

In this study, two strains of lactic acid bacteria (LAB) namely Weissella kimchii F28 and W. confusa MGl were used for the production of exopolysaccharides (EPS) from sucrose. Both strains produced glucan polysaccharides. In the case of W. kimchii F28, the EPS isolation procedure was performed six times, making modifications in order to optimize the yield of EPS. The maximum yield of EPS for this strain was 16 g per litre of culture. In the case of W. confusa MGl, the EPS isolation procedure was followed five times, resulting in a maximum yield of EPS for this strain of 34.4 g per litre of culture. This is a substantial yield for both strains, and permits large-scale production of EPS for various applications.
