Biofuels from Food Waste: Applications of Saccharification Using


Simultaneous saccharification and fermentation of sweet sorghum

The bioconversion of cellulosic wastes into high-value bio-products by saccharification and fermentation processes is an important step that can reduce the environmental pollution caused by agricultural wastes. Saccharification of biomass to fermentable sugar is a major constraint for bioethanol production due to high cost of enzyme production and complications associated with the removal of hearse acid, alkali and salts formed after neutralization. Separate saccharification and fermentation (SSF), simultaneous enzymatic hydrolysis and fermentation (SEHF), and consolidated bioprocessing (CBP) are the common approaches for ethanol fermentation. In SSF, optimized temperature can be used in the saccharification process to maximize the enzymatic activity, thereby effectively producing simple sugars. Here, Metal-Organic Frameworks (MOFs) coupling simultaneous saccharification and fermentation for butyric acid production using rice straw was constructed.

Background: Simultaneous saccharification and fermentation (SSF) is a promising process for bioconversion of lignocellulosic biomass. High glucan loading for hydrolysis and fermentation is an efficient approach to reduce the capital costs for bio-based products production. 2.3. Simultaneous Saccharification Filtration and Fermentation (SSFF) In SSFF, fermentation broth is circulated between the hydrolysis and fermentation vessels.
