Abstract
Tijekom proizvodnje mlijeka može doći do kontaminacije s različitim vrstama mikroorganizama, ali problem predstavljaju sporogene bakterije koje ne uništava pasterizacija, već samo sterilizacija. Jedna od grupe sporogenih bakterija su i bakterije iz roda Clostridium. C. tyrobutyricum i srodne vrste jedna su od najčešćih skupina bakterija odgovornih za kvarenje sira, ali mogu biti i prisutne u mliječnim proizvodima kao što je mlijeko u prahu. Cilj ovoga rada bio je utvrditi prisutnost bakterije C. tyrobutyricum i srodnih vrsta u svježem sirovom mlijeku i mlijeku u kamion cisterni kao potencijalnih kontaminanata mlijeka i uzroka kvarenja mliječnih proizvoda. Mali broj uzoraka svježeg sirovog mlijeka (25% obrađenih uzoraka) sadržavao je ispod 102 CFU/mL prisutnih klostridija, dok je znatno više bilo uzoraka (oko 40%) s više od 103 CFU/mL prisutnih klostridija. Mlijeko u kamion cisterni sadržavalo je 1,3 × 103 CFU/mL prisutnih klostridija.
Abstract (english)
Contamination with different types of microorganisms can occur during milk production, but the problem is sporogenic bacteria that are not destroyed by pasteurization, but only by sterilization. The group of sporogenic bacteria are bacteria from the genus Clostridium. C. tyrobutyricum and related species are one of the most common groups of bacteria responsible for cheese spoilage, but may also be present in dairy products such as milk powder. The aim of this study was to determine the presence of C. tyrobutyricum and related species in raw milk and milk in a tanker truck as potential milk contaminants and causes of spoilage of dairy products. A small number of raw milk samples (25% of processed samples) contained less than 102 CFU/mL clostridia, while significantly more samples (about 40%) contained more than 103 CFU/mL clostridia. The milk in the tanker truck contained 1.3 × 103 CFU/mL of clostridia.
