大约 30% 的稻壳（代表了几乎没有商业价值的丰富残留物）用 0.4 M H2SO4 酸溶解，生产出含有超过 100 g 单糖/升的糖浆。 Ca(OH)(2) 可减轻水解过程中产生的毒素。处理过的水解产物加上额外的营养物质与大肠杆菌 KO11 一起发酵，在 72 小时内产生超过 46 g 乙醇/L（理论产量的 92%）。
Approximately 30% of rice hulls, which represent an abundant residue with little commercial value, was solubilized with 0.4 M H2SO4 acid to produce a syrup containing over 100 g monomer sugar/l. Toxins generated during hydrolysis were mitigated with Ca(OH)(2). Treated hydrolysate plus additional nutrients was fermented with Escherichia coli KO11 to produce over 46 g ethanol/L in 72 h (92% of theoretical yield).
