Abstract

Svrha ovog rada bila je izolirati autohtonu mikrobnu populaciju iz uzoraka krčkog sira proizvedenih na obiteljskom poljoprivrednom gospodarstvu (OPG) otoka Krka. Provedena je izolacija i identifikacija autohtone mikrobne populacije u krčkom siru. Korištenjem klasičnih mikrobioloških i biokemijskih metoda identifikacije ustanovljena je prisutnost slijedećih bakterijskih vrsta: Lactobacillus brevis i Pediococcus acidilactici. Ovi bakterijski izolati pokazali su antimikrobnu aktivnost prema test mikroorganizmima (Salmonella sp., Lysteria monocytogenes, Staphylococcus aureus i Escherichia coli), najčešćim konataminantima u hrani.

Abstract (english)

The purpose of this study was to isolate the indigenous microbial population samples from cheese produced on the family farm from Krk. Isolation and identification of indigenous microbial population in mentioned products were performed. Used classical microbiological and biochemical methods of identification established presence of following bacterial species Lactobacillus brevis i Pediococcus acidilacticii. These strains have shown antimicrobial activity against test microorganisms (Salmonella sp., L. monocytogenes, S. aureus and E. coli), most common contaminants in food.
