Abstract
Mnogi mikroorganizmi, uključujući bakterije mliječne kiseline, mogu ukloniti ili smanjiti količine mikotoksina u hrani i krmi, a pokazuju i sposobnost vezanja mikotoksina u in vitro i in vivo uvjetima. Budući da o utjecaju mikotoksina na broj i morfološke karakteristike stanica bakterija nema uopće ili ima vrlo malo podataka, svrha ovog rada bila je odrediti utjecaj aflatoksina B1 (AFB1) i zearalenona (ZEA) na morfološke karakteristike i preživljavanje bakterije Lactobacillus plantarum B tijekom 72 sata. Mikrobni rast se često prikazuje krivuljom rasta pa je u ovom radu ista dobivena neizravnom metodom određivanja živih stanica (brojanjem poraslih kolonija na krutoj hranjivoj podlozi), izražena kao log CFU/mL. Od morfoloških karakteristika određivana je veličina stanica, korištenjem metode mikrometrije, uporabom objektnog i okularnog mikrometra. Iz dobivenih rezultata može se zaključiti da oba mikotoksina imaju slab utjecaj na morfologiju i rast stanica bakterije Lactobacillus plantarum B.
Abstract (english)
Many microorganisms, including lactic acid bacteria, can remove or reduce the amount of mycotoxins in food and feed as well as bind mycotoxins in vitro and in vivo. Since there are no available data and data on the influence of mycotoxins on number and morphological characteristics is very limited, the aim of this study was to investigate the effect of aflatoxin B1 (AFB1) and zearalenone (ZEA) on morphological characteristics and survival of Lactobacillus plantarum B during 72 hours. Microbial growth is often indicated by the growth curve, and in this work it was obtained by an indirect method of determination of live cells (by counting the growing colonies on a solid nutrient medium), expressed as log CFU/mL. As morphological trait, size of cells was determined by using the micrometric method, using the object and ocular micrometers. From obtained results it can be concluded that both mycotoxins have poor effect on morphology of cells as well as on cell growth of L. plantarum B.
