Production Of Yogurt
Starter culture for Yogurt
Two microorganisms namely, Lactobacillus bulgaricus and Streptococcus thermophilus, growing together symbiotically, are responsible for the lactic fermentation of the yoghurt. In some countries, apart from these two bacteria, the culture also contains lactose fermenting yeasts, Leuconostoc strains, Lactococcus lactis subsp. lactis biovar diacetylactis and Lactobacillus acidophilus.The method of maintaining purity of the yoghurt culture is very important and it is better to maintain the mother cultures individually rather than in mixed form.
