Processing of sugar beet in the sugar production industry generates sugar beet pulp as a by-product, which contains valuable cellulose, hemicellulose, and pectin. Valorization of sugar beet pulp into value added products through various techniques is cost effective and environmentally friendly. Recent biotechnological developments have unlocked the potential of sugar beet pulp as a feedstock for biofuels, biodegradable plastics, and platform chemicals.
The processing of sugar beet in the sugar production industry releases huge amounts of sugar beet pulp as waste which can be considered a valuable by-product as a source of cellulose, hemicellulose, and pectin. Valorization of sugar beet pulp into value added products occurs through acid hydrolysis, hydrothermal techniques, and enzymatic hydrolysis. Biochemical conversion of beet pulp into simple fermentable sugars for producing value added products occurs through enzymatic hydrolysis is a cost effective and eco-friendly process. While beet pulp has predominantly been used as a fodder for livestock, recent developments in its biotechnological valorization have unlocked its value as a feedstock in the production of biofuels, biohydrogen, biodegradable plastics, and platform chemicals such as lactic acid, citric acid, alcohols, microbial enzymes, single cell proteins, and pectic oligosaccharides. This review brings forward recent biotechnological developments made in the valorization of sugar beet pulp into valuable products.
