在不久的将来，木质纤维素的酸水解或酶水解是否会占上风的争论仍然是开放的。描述了不同类型的酸水解（使用浓酸或稀酸，并且在这种情况下使用极端温度，或尝试实现半连续或连续工艺）。每种情况的优点和不便之处都有描述，然而，与酶法相比，酸水解的改进余地有限。新的微生物、新的菌株和基因工程实际上正在改进经典的酶促过程。同时水解和利用所产生的糖将大大改变目前的困惑。在任何情况下，只有当半纤维素水解产物和木质素找到有利可图的用途时，木质纤维素水解的利用才具有商业利益。科学和技术界正在这方面作出相当大的努力。
The debate if acid or enzymatic hydrolysis of lignocellulosics will prevail over the other in the near future is still open. Different types of acid hydrolysis (use of concentrated acids, or diluted acids, and in this case use of extreme temperatures, or attempts to realize semi-continuous or continuous processes) are described. Advantages and inconveniences are described for each case.However, only a limited margin for improvement is left to acid hydrolysis, compared to the enzymatic one. New microorganisms, new strains, and genetic engineering are actually improving classic enzymatic processes. Simultaneous hydrolysis and utilization of produced sugars will substantially modify current perplexities. A survey of the present trends is given.In any case, the utilization of lignocellulosics hydrolysis will be of commercial interest only if hemicellulose hydrolyzates and lignin find profitable employment. Considerable effort is being made in this direction by both the scientific and the technical community.
