Lactic Acid Production Using Sweet Potato Processing Waste
Lactic Acid Production Using Sweet Potato Processing Waste

substrate from the sweet potato processing waste material that supports the growth of lactic acid bacteria, which results in the production of lactic acid. The sweet potato waste product was characterized, and found to contain 16.5% solids. The solids components were 18.5% ash, 4.4% protein, and the rest assumed to be carbohydrates.
