Some of the details are nice, such as the work of scientists trying to create enzymes to do the difficult job of breaking cellulose down to make ethanol.

其中一些细节阐释地很美，比如科学家如何设法合成那些可分解纤维素的酶以制造乙醇，这项科技攻关难度极大。

First you need to break cellulose down to sugars and then bacteria can convert them to ethanol.

首先，要把纤维素分解为糖，然后细菌再由转变为乙醇。

The results showed that glucose and xylose liberated from cellulose and hemicellulose in corn stover were rapidly fermented to ethanol by S.

研究表明，纤维素和半纤维素水解产生的葡萄糖和木糖被重组酵母S。

Next the company converted the microbe to produce means to create ethanol fuel from plant cellulose, and following scale-up and cost problems, abandoned that dream to focus upon higher cost chemicals used in cosmetics.

Even as producers have urged the EPA to lift this bar, it has challenged them to move beyond corn and make ethanol from cellulose, the abundant, inedible portion of most crops.

Corn ethanol also has no chance of curing the nation's addiction to foreign oil. (Ethanol from cellulose would be more of a winner, but the technology does not yet exist.) Neither of these inconvenient truths will necessarily prevent U.S. politicians from bailing out the distillers.
