摘要: Abstract Surface response methodology was used to study the effects of three variables, viz. total reducing sugars (116–222 g l −1 ), yeast inoculum concentration (10–30%) and supplemented inorganic nitrogen as (NH 4 ) 2 SO (1–3 on production ethanol. The complete incomplete factorial designs (3 3 were compared through residual analysis variance. Since there no statistically significant difference at 5% level, basis cost-efficiency space limitations, it recommended use design constituting 12 treatments with repetitions in central point totalling 15 experiments which control batch alcoholic fermentation.
