酶是由基因改性的细菌或者真菌生产的，与白蚁的唾沫，而白蚁因为能分解纤维素而臭名昭著。

The enzymes are usually made by gene-modified bacteria or fungi and resemble the saliva of termites, which is notoriously good at dissolving cellulose.

它的另一大优势在于可以充分分解纤维素，防止废弃的纤维素——例如草秆和木屑——造成生物污染。

Another advantage of the fungus is its ability to eat up cellulose, the compound that makes up much of the organic waste that is currently discarded, such as stalks and sawdust.

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。

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.
