Acetyl-4, 4′-diapolycopene-4, 4′-dioate, a C30 carotenoid and secondary metabolite, was produced by the Sporosarcina aquimarina bacteria using a 5.0 L fermentation vessel with a 3.0 L working volume. In the presence of tryptone, the biosynthesis of acetyl-4, 4′-diapolycopene-4, 4′-dioate production using a batch fermentation process was further improved. Production parameters like carbon source, pH, and temperature were studied, and maximum product was achieved, up to 1.2 g/L, where the secondary metabolite yield was 0.07 g/L and productivity, 0.00833 g/L/h. The organic constitution and significant red color intensity of the acetyl-4, 4′-diapolycopene-4, 4′-dioate molecule can be used in the textile industry as a dye, and a coloring additive in processed foods and pharmaceuticals...
