很多小细胞→纤维素
cellulose
常考释义
So researchers at this company have discovered some microorganisms that process cellulose and produce ethanol.
所以这个公司的研人员已经发现了一些微生物，这些微生物可以把纤维素转化为乙醇。

Food chemists probably can improve upon the efficiency and economics of the ruminant’s conversion of cellulose to nutrients.
反刍动物将纤维素转化为营养素的效率和经济性有可能经过食品化学家来改进。
So researchers at this company have discovered some microorganisms that process cellulose and produce ethanol.
所以这个公司的研人员已经发现了一些微生物，这些微生物可以把纤维素转化为乙醇。
来源于：听力OFFICIAL39 L6I mean, the best key to unlocking the power of cellulose may well lie in a rare species of bacteria or yeast in a jungle somewhere.
我的意思是，开发纤维素所含能量的关键可能藏在某个丛林里的特殊种类的细菌或者酵母身上。
来源于：听力OFFICIAL39 L6That is, have a single organism that breaks down cellulose and then produces ethanol.
意思是，我们可以找到一种有机物，既可以分解纤维素也可以把它转化成乙醇。
来源于：听力OFFICIAL39 L6Thing is, though, we are not too good at producing the enzymes that break down cellulose.
问题是，我们在生产这些分解纤维素的酶的时候并没有很成功。
来源于：听力OFFICIAL39 L6And second, after the enzyme has broken down the cellulose, yeast and other microorganisms, microbes are added to ferment those sugars into cellulosic ethanol.
第二点，在酶把纤维素分解了之后，酵母和其他的微生物、细菌等会被加入，来发酵这些糖类，最后生成纤维素乙醇。

来源于：听力OFFICIAL39 L6So one thing I want to do today is consider one of those potential energy sources: cellulose.
我今天要做的事情之一就是来讨论其中一种潜在的能源来源之一就是：纤维素。
来源于：听力OFFICIAL39 L6After microorganisms have broken down the cellulose, we're left with two things: the microbe's waste and the more resistant plant material that microorganisms can't break down easily.

来源于：听力OFFICIAL37 L2Professor: Yes. And it's been very hard to develop a controlled way to process cellulose in a lab so that we can use the energy that's stored in it.
