A pilot plant nutrient study was performed with fed-batch fermentation mode, 10% seed inoculum, and the sugar concentration needed to obtain 9% (v/v) ethyl alcohol using high test molasses. The nutrients consisted of ammonium sulfate (2 g/L), ammonium phosphate (0.5 g/L) and yeast nutrient (1 g/L) for treatment 1, and ammonium sulfate (2 g/L) for treatment 2. After 24 hours, samples were analyzed for alcohol yield and congener composition. The additional nutrients for treatment 1 sped up the fermentations and thus increased yields at 24-hour fermentation time.
