Bioconversion of Carrot Pomace to Value-Added Products: Rhizopus delemar Fungal Biomass and Cellulose

Carrot pomace (CP) which is generated in a large volume the juice production process, rich cellulose, hemicellulose, sugars, pectin, and minerals. However, many previous investigations, only cellulose was purified utilized while other components of CP were discarded as waste. Here, valorized into fungal biomass with aim utilizing all components. Enzymatic pretreatments applied to solubilize digestible fraction including sucrose, sugars for cultivation, remained intact solid fraction. The dissolved substrate cultivation an edible fungus (Rhizopus delemar). Fungal performed shake flasks bench-scale bioreactors. highest concentration obtained after pretreatment invertase (5.01 g/L) 72 h (36 42% higher than concentrations hemicellulase pectinase treatments, respectively). Invertase resulted hydrolysis could then be taken up by fungus. Carbohydrate analysis showed 28–33% glucan, 4.1–4.9% polysaccharides, 0.01% lignin, 2.7–7% ash residues enzymatic pretreatment. Fourier transform infrared spectroscopy thermogravimetric also confirmed presence this has high potential food or feed applications, raw material development biomaterials. Cellulose from used applications such biobased-textiles membranes wastewater treatment, where pure needed.
