Sažetak
Most of the food and feed are contamination sensitive to molds in various stages of production, processing, transportation and storage. Thus, climate conditions and conditions during the production process, transport and storage can enhance the growth of molds and mycotoxin synthesis. Reduced utilization of chemical compounds added in order to preserve and protect food and animal feed is required in modern production. So, lactic acid bacteria which produce metabolites with antifungal effect and prevent spoilage of food and feed by undesirable molds have been used. Therefore, in this paper antifungal activity of isolate of lactic acid bacterium Lactobacillus plantarum K1 on the growth of mold Aspergillus ochraceus ZMPBF 318 in broth (yeast extract) at 28 °C for 28 days was investigated. Investigation of the growth of the mold was carried out in the broth with addition of supernatant of fermented broth in which bacterium Lactobacillus plantarum K1 grew and in the presence of the
bacterial cell suspension. The results show that during fi rst 14 days of incubation the mold growth was significantly inhibited by cell suspension of bacterium Lactobacillus plantarum K1, while good inhibitory effect of the supernatant on the growth of the mold was obtained with longer incubation time.
