Introduction Yeasts are a Leading cause of spoilage of yogurt‚ doogh and fermented milks in which the low pH provides a selective environment for their growth (Fleet‚ 1990; Rohm‚ Eliskasses‚ & Bräuer‚ 1992; Hansen and Jakobsen‚ 2004). Yogurts and doogh having initial counts of >100 CFU/g tend to spoil quickly. Yeasty and fermented off-flavors and Swelling of the doogh and yoghurt package are often detected when yeasts grow to 105–106 CFU/g (Fleet‚ 1990). Green and Ibe (1986)‚ Viljoen et al (2003)
