Abstract. The effect of different concentrations of ATCC vitamin supplement on the production of purple non-sulfur bacteria biomass (suspended and biofilm), carotenoids (Crts) and bacteriochlorophylls (BChls) from fuel-synthesis wastewater (FSW) was investigated in this study. The results suggest that maximum COD removal (3465 ± 125 mg/L) from FSW was obtained at a vitamin media concentration of 10 mL/L. The best optimal condition for increased biomass production from suspended and biofilm culture is the addition of vitamin at concentrations of 20 mL/L and 10 mL/L, respectively. The optimum condition for maximum Crts and BChls production from suspended and biofilm culture was found as 5 mL/L and 0 mL/L, respectively. Hence, the biomass response to vitamins is complex and vitamin addition can be used to prioritize different end goals with purple-non sulfur bacteria treatment systems and biomass utilization.
