Changes, choices and contradictions | A case study of bakers and yeast

The unruly and wild Lactic Acid Bacteria (LAB) has more than a 5000 year old symbiotic relationship with us. The magic of combining airborne and human borne bacteria with warmth, water and the dormant bacterial microbes in the wheat bran, form a natural starter culture for leavening bread. An ancient process of harnessing nature. Described by scientists as, “one of the oldest bio-technological processes” which ensures that an ancient bacteria such as Lactobacillus sanfranciscensis does not become extinct (Rollán et al, 2010, 1168) .
