Fig. 5From: Contribution of proteases and cellulases produced by solid-state fermentation to the improvement of corn ethanol productionEffect of each enzymatic purified fraction on ethanol production after 51 h of corn mash fermentation, as % of the increase obtained with the addition of the crude extract (100%) compared with control condition (0%). Error bars represent standard deviation (n = 2). The crude extract was added at equivalent of 1-kg dry product/T corn; the fractions were added at iso-enzymatic activity compared to the crude extractBack to article page
