Lactic Acid Bacteria (LAB) can be used as food preservatives to improve food stability and safety. This is due to its ability to produce antimicrobial substances which can inhibit the growth of the food poisoning organisms. LAB produce antimicrobial compounds named bacteriocins. This study focused on bacteriocin named reuterin which produced from Lactobacillus reuteri strain and its optimal production condition. The metabolite L. reuteri bacteriocin (reuterin) was extracted and the antimicrobial activity was evaluated against some hospitalized bacterial and fungal pathogens. The reuterin producing L. reuteri exhibited the highest inhibition zone (22.2, 22.5 and 22.7 mm) against E. coli, Staphylococcus aureus and Candida albicans, respectively, when grown on optimized condition, i.e., growth on 2% glucose, soy bean (sb) or yeast extract as nitrogen source, all MRS salts medium and inoculated by 21 × 108 cfu/ml, pH 6.5 at 37°C for 24 hr anaerobically. This study gave us the possibility to use reuterin as food preservative to control pathogenic microorganisms and food spoilage.
