Abstract

Svrha je ovoga istraživanja bila identificirati i okarakterizirati potencijalne autohtone funkcionalne starter kulture izolirane iz domaće kobasice proizvedene od konjskog mesa. Dominantnu su mikrofloru u uzorcima kobasica činile bakterije mliječne kiseline (BMK), a zatim mikrokoki. Od bakterija mliječne kiseline prevladavale su vrste Lactococcus lactis ssp. lactis i Lactobacillus plantarum. Vrsta Lactococcus lactis ssp. lactis nije uobičajena u fermentiranim kobasicama, pa smo ju okarakterizirali kao potencijalnu funkcionalnu starter kulturu. Vrsta Lactococcus lactis ssp. lactis proizvela je značajnu količinu mliječne kiseline, a uspješno je rasla pri 12, 18 i 22 ºC, te u prisutnosti 5 % NaCl. Također je dobro podnijela liofilizaciju i simulirane uvjete želučanog soka i soka tankog crijeva. Osim toga, uspješno je suzbila rast patogena i pokazala je dobra adhezijska svojstva in vitro.
