Antimicrobial activity of lactic acid bacteria isolated from locally fermented cow milk products sold in Keffi, Nigeria on clinical bacteria

Lactic acid bacteria (LAB) are renowned for the potential of producing antimicrobial compounds. This study focuses on isolation and effect lactic isolated from locally fermented cow milk products (Nono, Kindirmo Maishanu). The LAB isolates against clinical test was also investigated. Fifty (50) samples each Nono Kindirmo, twenty-five (25) Maishanu were collected sellers in Keffi, Nasarawa State Nigeria. Standard microbiological methods used identification products. percentage rate Lactobacillus species showed that 52.0% 58.0% kindirmo. highest occurring plantarum (14.0%) kindirmo delbrueckii (16.0%). screened antibacterial activity it observed seven (7) able to show inhibition zones. culture supernatant Staphylococcus aureus, Escherichia coli Shigella dysenteriae investigated using agar diffusion technique. 22.00mm by dysenteriae, while least zone 15.00mm acidophilus E. coli. In conclusion, zones this research strongly suggest various compounds (lactic acid, acetic propionic bacteriocins) produced during fermentation process potent control growth bacteria.
