โดยสรุป In summary, as regards ethanol production from unwashed pretreated biomass, pretreatment D would be a highly recommendable method,
since substantial amounts of ethanol were obtained compared to methods A, B, and C, even without the pretreated biomass having been washed. Ethanol concentration in sample D was more than 90 times the control, thus showing that alkaline peroxide is a highly effective method which greatly enhances production of this biofuel from wheat straw.
