Resumo

Valorization of waste generated during industrial process has gained considerable attention in re-cent years. The citrus industry produces high amount of waste that can be used to obtain biomole-cules with significant economic value. This study aims to investigate the potential of citrus by-product (CB) as carbon source for the co-production of red colorants (RC) and enzymes by the fil-amentous fungi Talaromyces amestolkiae in submerged cultivation using an orbital shaker. The microorganism was able to metabolize the CB employing their sugars as carbon source to the pro-duction of RC achieving a colorant yield of 0.016 g.L-1h-1 for batch when the culture media was supplemented with glucose and glutamate monosodium. Alongside the production of colorants, the microorganism also produced enzymes, including endo-glucanases, xylanase, and & beta;-glucosidase (with the latter being the most abundantly produced, specifically 2.8 U/mL). Al-though the economic analysis of the process indicated that further improvements are required to make the current production of this colorant economically viable, especially if citrus waste is uti-lized as the main source material. Considering a biorefinery approach, the results achieved in this study are quite promising, given the generation of high commercial value commodities, such as natural colorants and enzymes, using citrus by-product.
