Sour culture, in the context of bread, refers to an active culture of naturally occurring lactobacilli and yeasts that is used in the traditional and ancient process of making bread. It is more common just to refer to this as your "starter" or "sourdough starter," but it is becoming more common to see this as an ingredient on a package of bread. Though sour culture is yeast, it is not baker's yeast, but the naturally occurring yeast culture that has been the leavening agent in bread for thousands of years. (Most modern commercial breads use some chemical leavening agent like baking powder to make bread rise.) There may be variations on the generic sour culture which may be based on different grains which are used in different geographical regions by different cultures, but it is still the basic biological entity historically used in making bread or pastry.
