In general, homemade yogurt needs Lactobacillus bulgaricus and Streptococcus thermophilus for fermentation, and most of the yogurt and bacterial powder sold in the market can be used as strains for making yogurt. If you choose yogurt sold in the market as the strain of fermented yogurt, you should try to choose refrigerated yogurt with fresh production date; If you choose bacterial powder as the strain of fermented yogurt, then you should choose freeze-dried bacterial powder, which can play a fermentation role in an environment with suitable temperature. Here I will share with you several popular bacterial powders.
