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.
To make sure your yogurt contains active cultures, check the label. Most brands will have a graphic that says ''live and active cultures.''. If you want to know which specific active cultures your yogurt contains, look to the label again. Under the list of ingredients, many brands list the specific active cultures. For Activia by Dannon, for example, L.Bulgaricus, S.Thermophilus, and bifidobacterium are listed. This particular yogurt contains the probiotic culture bifidus regularis, which works to regulate your digestive system.
