The plan is to develop ways of making anode carbon from lignin, a natural polymer found in the cell walls of plants.

该计划是开发利用木质素制造阳极碳方法，木质素是一种存在于植物细胞壁中天然聚合物。

They break down the lignin and the cellulose, which is the most resistant form of carbon, and they break it down, produce mushrooms.

The bark covering tree trunks is full of lignin, a rigid web of compounds that's tough to chew and highly impermeable to pathogens.

覆盖在树干上树皮充满了木质素，这是一种坚硬合物网， 难以咀嚼，而且病原体极难渗透。

Velev and Ph.D. student Alexander Richter discovered that silver-based nanoparticles can be replaced with non-harmful nanoparticles based on an organic polymer called lignin, naturally found in most plants.

This tissue is what allows modern trees to grow tall and straight, because it contains lignin, a rigid organic polymer that gives the plant structural support.

这种组织使现代树木能够长得又高又直，因为它含有木质素， 一种为植物提供结构支撑刚性有机聚合物。

And back in the Carboniferous, many of the decomposing microbes that could break down the hardy lignin -- and release CO2 as a result -- had yet to evolve.

To avoid taking those extra steps, expert composters might add extra wood chips or paper products to the pile, since they have a lot of lignin — a tough component of plant cell walls which doesn't contain any nitrogen at all.

为了避免这些额外步骤，专业堆肥者可能会往堆肥中再加入一些木屑或者纸质品，因为它们含有大量木质素，一种完全不含氮坚韧植物细胞壁成分。

Insects like termites can go whole hog on the whole log, because they can " chew" the wood with their serrated mandibles AND also have the right gut machinery - AKA microbes - to break the lignin down on the molecular level.

像白蚁这样昆虫可以吃掉整根原木，因为它们可以用锯齿状下颚“咀嚼” 木材，并且还有合适肠道机制——也就是微生物——在分子水平上分解木质素。
