Enterococcus faecalis BFE 1057 isolated  from a Nigerian fermented  dairy  product ('nono') produced a bacteriocin designated enterocin  NA. It was found inhibitory  towards  Lactobacillus, Enterococcus and Listeria strains. Enterocin  NA was inactivated by proteolytic enzymes, and resistant  to heating at 80 °C for 30 min and active at pH 2.0 to 8.0. Its molecular  weight was estimated by ultrafiltration  to be above 3000 daltons. The ability of this bacteriocin  to inhibit Listeria is of potential  interest  in food safety and enterocin  NA may have future applications as a food preservative.
