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制造阳极碳的方法，木是一种存在于植物细胞壁中的天然聚合物。

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

它们分解木纤维， 这是最耐腐蚀的碳形式，然后将其分解， 产生蘑菇。

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

覆盖在树干上的树皮充满了木，这是一种坚硬的合物网， 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， 一种为植物提供结构支撑的刚性有机聚合物。

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.

While wood is made up of the same nutritious carbohydrate called cellulose that makes up other tasty tree parts, most of the cellulose in wood is bound together by a complex molecule called lignin.

虽然木材是由一种叫做纤维的营养碳水合物构成的，这种碳水合物构成了其美味的树木部分，但木材中的大部分纤维是由一种叫做木的复杂分子结合在一起的。

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.

为了避免这些额外的步骤，专业的堆肥者可能会往堆肥中再加入一些木屑或者纸品，因为它们含有大量木，一种完全不含氮的坚韧的植物细胞壁成分。

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.

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