Abstract

U ovom je radu istražen rast odabranih plijesni Aspergillus ochraceus ZMPBF 318, Aspergillus parasiticus ZMPBF 2999, Penicillium expansum ZMPBF 566, Fusarium graminearum ZMPBF 1244 i Trichothecium roseum ZMPBF 1226 u prisutnosti supernatanata bakterija mliječne kiseline (BMK) Lactobacillus acidophilus M92 i Lactobacillus plantarum L4. Istraživanja su pokazala da stanice BMK i L. plantarum L4 i L. acidophilus M92 pokazuju značajno inhibitorno djelovanje na rast plijesni iz roda Penicillium, Trichothecium i Fusarium, dok je njihov utjecaj na rast plijesni iz roda Aspergillus bio neznatan ili nije dokazan. Supernatant bakterije L. plantarum L4 pokazuje snažnije inhibicijsko djelovanje na sve odabrane sojeve plijesni, dok supernatant bakterije L. acidophilus M92 inhibira samo rast plijesni T. roseum, dok je rast ostalih odabranih sojeva znatno inhibiran samo pri koncentracijama supernatanta od 30-40 µL/disku.

Abstract (english)

In this abstract conditions of mold growth Aspergillus ochraceus ZMPBF 318, Aspergillus parasiticus ZMPBF 2999, Penicillium expansum ZMPBF 566, Fusarium graminearum ZMPBF 1244, Trichothecium roseum ZMPBF 1226, were researched. The research showed that cells of lactic acid bacteria L. plantarum L4 i L. acidophilus M92 show significant inhibitory effect on the mold growth of lactic acid bacteria Penicillium, Trichothecium and Fusarium, although the influence on the growth from the strains Aspergillus is not proven. The supernatant from the bacteria L. plantarum L4 shows a much stringer inhibitory growth on all of the selected starins. The supernatant from the bacteria L. acidophilus M92 inhibits the growth only of T. roseum, though the growth of all the remaining strains is inhibited while using concentrations of 30-40 µL/disc.
