Abstract

Banana peels is a waste which has not been widely used, so that the relatively long time the existence of such waste brings its own problems such as pollution. Banana peels contain high enough lignocellulosic and can be degraded into simpler forms. The Lignin content of banana peels needs to be removed/destroyed structure. The purpose of this study was to determine the effect of the addition ratio of Trichoderma reseei and Aspergillus niger on hydrolysis liquefaction and saccharification time in stage hydrolysis to glucose produced with the highest glucose parameters. In this study, the method was used to degrade lignin by using sulfuric acid (2%). Afterward, the cellulose content was changed in liquefaction process. Hydrolysis liquefaction performed using Aspergillus niger and Trichoderma reesei with a mixture ratio of 1: 0, 0: 1, 1: 1 and 1: 2. Furthermore, substrate hydrolysis liquefaction saccharification going …
