The water-soluble (WS) portion obtained by supercritical water treatment of lignocellulosics was studied for its fermentability to ethanol. A fermentation test of the WS portion showed it was not fermented to ethanol. Therefore, a wood charcoal treatment was applied to the WS portion to remove furan and phenolic compounds, which are thought to be the inhibitors to sugar fermentability. It was found that treatment with wood charcoal can be effective at removing these inhibitors and improving the fermentability of the WS portion without reducing the levels of fermentable sugars.
对通过超临界水处理木质纤维素获得的水溶性（WS）部分进行了乙醇发酵性研究。WS部分的发酵试验表明其不能发酵成乙醇。因此，对WS部分进行了木炭处理以去除呋喃和酚类化合物，这些化合物被认为是糖发酵性的抑制剂。结果发现，用木炭处理可以有效去除这些抑制剂，并提高WS部分的发酵性，同时不降低可发酵糖的水平。
