Glucan conversion for untreated (yellow) and ammonia fiber expansion (AFEX)-treated (green) whole corn plant (WCP) (open bars, 12 h; striped bars, 168 h) for different loadings of commercial enzymes and hydrolysis conditions (time of enzyme addition). Spezyme CP (C) (23 mg/g of glucan), Novozyme 188 (N; 38 mg/g glucan) and Stargen (S) (5 mg/g glucan) were added as depicted on the X-axis at the respective time points (t = 0 or 12 h). The theoretical maximum possible glucose yield from WCP is 718 g glucose per kg dry weight biomass.
