Cellulose bacterial is cellulose formed by bacteria sugar content in waste. Cassava-based industrial liquid waste contains sugar (5-7)%. so it has the potential as a substrate because it meets the minimum glucose requirements of (6-7)% to form cellulose bacterial. The waste was obtained from liquid waste from home industry cassava rengginang in Nyamok Village. https://fitnessgravesyardes.shop/product-category/ent-board/
