“…The main byproduct of the su gar industry is molasses that is obtained during the crystallization process of sugar. Some studies revealed that for every tonne of sugar produced, about 40 to 60 kg of molasses are generated as a byproduct (Oliveira Filho, Mattos, Pereira, & Baptista, 2019), thus being an abundant and renewable carbon source that can be used as a substrate for fermentation processes. Therefore, several studies have shown interest in using molasses in the fermentative processes for the production of biomolecules such as bi oethanol, single cell oil, pigments, and microbial polysaccharides (Arshad, Abbas , & Iqbal, 2019;Bento, Carvalho, Reis, & Castro, 2020;Dias, Reis, Santos, & Silva., 2020;Wang, Kim, Lee, Kim, & Joe, 2020).…”
