Abstract:
Eight strains of lactic acid bacteria producing bacteriocin were isolated from Burkina Faso fermented milk samples. These strains were identified to species: Lactobacillus fermentum, Pediococcus spp., Leuconostoc mesenteroides subsp. meseteroides, Lactococcus. Isolated bacteriocin exhibited antibacterial activity against Enterococcus faecalis 103907 CIP, Bacillus cereus 13569 LMG, Staphylococcus aureus ATCC 25293, Escherichia coli 105182 CIP using the agar drop diffusion test. The inhibition diameters obtained with bacteriocin are between 8 mm and 12 mm. Gram-positive indicator bacteria were most inhibited. The activities of the bacteriocin were lost after treatment with all the proteolytic enzymes (alpha-chymotrypsin, trypsin, pesin), whereas treatment with lipase, catalase, alpha-amylase did not affect the activity of the bacteriocin.
