Four samples of akamu were evaluated for the presence of antimicrobial producing lactobacilli. Thirty (30) lactobacilli were isolated from these samples. They inhibited the growth of Staphylococcus aureus and Escherichia coli, four of these isolated lactobacilli were chosen and when evaluated by agar well diffusion test, they inhibited the growth of the selected indicator organisms. The spectra of activity were evaluated against five different organisms. The highest activity was against Proteus mirabilis and the least against Salmonella sp. Key words: Bacteriocin, Lactobacilli, akamu, inhibition.
