A study by Osaka Metropolitan University found that persimmon tannin helps the yeast Saccharomyces cerevisiae grow 8.9 times better in ethanol, attributing this to the antioxidative properties of the tannin which reduce stress but do not protect cell membranes.
While ethanol in alcoholic drinks can impair motor functions, it can also fuel vehicles in a cleaner, more eco-friendly way. The production of ethanol requires yeast, which, ironically, is stressed by ethanol, affecting its growth. In the pursuit of efficient bioethanol production, researchers are exploring substances that enhance yeast’s resilience to ethanol, though they have identified only a few effective options so far.
