Inhibicijski učinak kozjeg i kravljeg mlijeka fermentiranog bakterijom Bifidobacterium longum Bb-46 na rast uropatogenog soja Candida albicans

Cilj ispitivanja bio je utvrditi antagonistički utjecaj kozjeg i kravljeg mlijeka fermentiranog probiotičkom bakterijom Bifidobacterium longum Bb- 46 na rast uropatogenog kvasca Candida albicans. Hipoteza u ovom radu bila je da fermentirano kozje mlijeko ima moguće jače inhibicijsko djelovanje na rast Candida albicans u usporedbi s fermentiranim kravljim mlijekom. Povrh toga, praćene su korelacije između stupnja inhibicije i određenih parametara mliječno kisele fermentacije (broj stanica Bifidobacterium longum Bb-46 i pH vrijednost). Rezultati istraživanja pokazali su da fermentirano kozje mlijeko značajno jače inhibira rast Candida albicans u odnosu na fermentirano kravlje mlijeko (P<0,05). Nije utvrđena nikakva korelacija stupnja inhibicije rasta Candida albicans s pH vrijednosti fermentiranog mlijeka i brojem živih stanica Bifidobacterium longum Bb-46 u fermentiranom kozjem i kravljem mlijeku.
The study was carried out to determine the antagonistic influence of goat and cow milk fermented with Bifidobacterium longum Bb-46 on uropathogenic Candida albicans strain. The hypothesis of this study was that fermented goat milk could have possible stronger inhibitory effect on the growth of uropathogenic yeast Candida albicans than fermented cow milk. The correlation between the inhibitory effect and the time of fermentation (number of viable Bifidobacterium longum Bb-46 cells and pH of fermented milk) was also determined. The obtained results have shown considerably higher inhibitory effect of fermented goat milk on the growth of Candida albicans compared with fermented cow milk. There was no significant correlation between number of Bifidobacterium longum Bb-46 cells in fermented and the inhibitory effect; as well as between changes in pH during fermentation and inhibitory effect of fermented goat or cow milk.
