Isolation and Identification of Autochthonous Lactic Acid Bacteria from Commonly Consumed African Indigenous Leafy Vegetables in Kenya

چکیده
African indigenous leafy vegetables (AILVs) are plants that have been part of the food systems in Sub-Saharan Africa (SSA) for a long time and their leaves, young shoots, flowers, fruits seeds, stems, tubers, roots consumed. These high vitamins, minerals, protein, secondary metabolites promote health. This study aimed at isolating, characterizing, identifying dominant lactic acid bacteria (LAB) from naturally fermenting commonly consumed AILV Kenya. A total 57 LAB strains were isolated identified based on phenotypic 16S rRNA gene analyses three AILVs (23 nightshade 19 cowpeas 15 vegetable amaranth). The highest microbial counts recorded between 48 h 96 fermentation all ranging approximately log 8 to 9 CFU/mL with an average pH 3.7. Fermentation was dominated by twenty eight Lactobacillus spp. [Lactiplantibacillus plantarum (22), Limosilactobacillus fermentum (3), Lactiplantibacillus pentosus (2) casei (1)], eleven Weissella (Weissella cibaria (8), W. confusa (2), muntiaci) six Leuconostoc [Leuconostoc mesenteroides Leuc. citreum lactis Pediococcus pentosaceus, four Enterococcus [Enterococcus mundtii E. faecalis (1) durans (1)] and, finally, two Lactococcus garvieae. used as starter cultures potential probiotics.

The presence of lactic acid bacteria (LAB) in fermented foods improves the health safety of food. Flavour development in dairy fermentations rises from a series of biochemical processes, and to restore the unique characteristics of traditional dairy varieties is to evaluate new wild LAB strains being isolated from good quality raw-milk. In order to study LAB biodiversity and to evaluate their p...
