Identification of exopolysaccharides-producing lactic acid bacteria from Burkina Faso fermented milk samples
AbstractSpacer region between 16S and 23 S rRNA genes of thirteen lactic acid bacteria strains from Burkina Faso fermented milk samples were amplified by the polymerase chain reaction (PCR). Lactobacillus delbrueckii, Lactobacillus acidophilus, Lactobacillus fermentum, Streptococcus thermophilus, Pediococcus spp, Leuconostoc mesenteroides subsp mesenteroides were identified. The Lactobacillus group was the predominant bacteria. Plasmids identified ranged between 2000 and 4000 bp. Exopolysaccharides (EPS) production varied from 181 mg/l and 814 mg/l, monomer analysis showed that glucose and galactose were predominant.
Key Words: Lactic acid bacteria, fermented milk, PCR, exopolysaccharides.
