Frequency of incidence of S. thermophilus in the different samples of milk and milk products was variable with the highest in the dahi followed by yogurt and lassi and a very low incidence in case of milk and cheese.On screening for folate using a microbiological assay with a tri-enzyme extraction, about 15% of strains was found to produce folate in the range of 40–50 μg · L−1, 35% in the range of 20–30 μg · L−1, and the remainder in the range of 4–16 μg · L−1.

在 Dali 样品中, 嗜热链球菌含量较高,其次是酸乳和 lassi, 由此可见, 在这些牛乳和发酵乳制品中的菌株生物多样性为嗜热链球菌占主要部分。 采用三重酶提取微生物学测定法筛选产叶酸菌株, 发现约 15% 的菌株产叶酸的范围为 40-50 μg·L-1, 35% 的菌株为 20-30 μg·L-1, 其余的则在 4-16 μg·L-1 之间。
