Typical costs: Having a contractor level and prepare the area then pour a concrete slab ranges from $1,000-$2,000 for a 10x20-feet; $4,000-$6,000 for 80x20-feet; and $5,000-$10,000 for 100x100-feet. Smaller projects cost more per square yard because of minimum travel, labor and equipment costs.
What makes yogurt - well, yogurt? The words live and active cultures refer to the living organisms, Lactobacillus bulgaricus and Streptococcus thermophilus, which convert pasteurized milk to yogurt during fermentation. Note that the milk is pasteurized before culturing to remove any harmful bacteria.
Old-fashioned Greek yogurt is made with goatâs milk while American yogurt, and many of the American-made âGreek-styleâ products, are made from cowâs milk. (âGreek-styleâ yogurts may also contain thickening agents like condensed milk or gelatin.) All yogurt starts out the same, with milk and live cultures. In the case of Greek yogurt, the live cultures are the active bacteria S. thermophilus (St) and L. bulgaricus (Lb), which ferment the milk to make its characteristic tangy taste. With Greek yogurt, the milk and culture combo is then strained with a filter to remove the liquid whey part of milk.
