Probiotic Potential Of Bacterial And Yeast Isolates From Nunu (African Fermented Milk):- Olayemi Samuel K

ABSTRACT Nunu is a spontaneously fermented milk (yoghurt-like) product in Ghana and other parts of West Africa including Nigeria and Burkina Faso. Unlike other African fermented milk products where milk of goats, sheep, and camels is used, Nunu is solely prepared from cow milk. The traditional processing of Nunu involves collecting fresh cow milk into containers and then allowing it to ferment for a day or two days at ambient temperature. Nunu is yoghurt-like in taste (a sharp acid taste) and it can be taken alone or with Fura. In Africa, bacteria and yeasts play a significant role in the fermentation of food, aroma formation and maturation. The importance of probiotics as a part of a healthy diet necessitated the investigation of these potentials in bacteria and yeasts isolated from nunu Isolates were identified as Lactobacillus species, Bifidobacterium species, Lactococcus lactis, pedicocus enterococcus species, SccCaaromyces cerevisiae, Candida chilensis, Candida tropicalis, zygosaccharomyces, kleyvaromyces . The isolate? were subjected to acid and bile tolerance, salt tolerance,. Strong acidification and {tolerance to bile, salts wen. recorded. samples and showed strong probiotic potential
