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屑或者纸品，因为它们含有大量，一种完全不含氮坚韧植物细胞壁成分。

There's the lignin and cellulose of plants, calcium-rich shells of mollusks and coral reefs, and mineral bones like ours.

And lignin is converted into all kinds of aromatic chemicals that flavor the meat, and can even act as chemical preservatives.

被转为各种芳香学物，给肉调味，甚至可以作为学防腐剂。

芬兰林产品公司 Stora Enso 认为它可以用制造阳极材料。

It's like, I wanted to bend, lignin, get out of my face.

就像，我本想弯曲，但，它却硬是不让，非得挡在我面前。

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.

像白蚁这样可以吃掉整根原，因为它们可以用锯齿状下颚“咀嚼” 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。

A second is to produce plastic free cardboard cartons which can be used as food containers and then recycled The third is to find employment for lignin a byproduct of the pulping process, which is at the moment.

第二个是生产无塑料纸包装盒，可以用作食品容器，然后进行回收。第三个是找到用途，是制浆过程中副产品，目前还没有很好利用方法。

And the theory goes that the lignin and zinc, selenium, vitamin E, the essential fatty acids in these seeds could influence estrogen and progesterone activity, so the hormones involved in your cycle.

其理论依据是，这些种子中、锌、硒、维生E以及必需脂肪酸可能会影响雌激和孕酮活性，即影响你月经周期中激变。

Their ability to grow so tall is the result of lignin, a chemical that is the building block of wood, which first appeared in plants as early as 400 million years ago.

它们之所以能长得这么高， 是因为，一种构成材学物， 早在 4 亿年前就出现在植物中。

Well the fungi are important, even though they make something like 5% of the living things in the rumen, they can breakdown specific bonds between the lignin inside the cellulose.

真菌很重要， 尽管它们在瘤胃中活体占比只有大约5%，但它们能够分解纤维内部之间特定学键。

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.

而在石炭纪，许多能够分解坚韧并释放二氧碳微生物尚未进出来。

All of the bonds in the molecules of cellulose and lignin that make up the wood contain energy, and some of them could be broken, releasing that energy.

构成材纤维和分子中所有学键都含有能量，其中一些键可以被打破，从而释放出这些能量。

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

树皮覆盖着树干， 富含，这是一种坚硬合物网络， 难以咀嚼且对病原体高度不渗透。

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

它们分解和纤维， 这是最耐腐蚀碳形式，然后将其分解， 产生蘑菇。

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

该计划是开发利用制造阳极碳方法，是一种存在于植物细胞壁中天然聚合物。

It's basically a band, a ring made of lignin, you know, like woody material that gets impregnated into the cell walls.

它基本上是一条带状结构，一个由构成环，也就是那种像头一样物，会渗入细胞壁中。

Remember how Sandy said the cellulose cells in trees are stuck together with a natural glue called lignin?

还记得Sandy说过，树中纤维细胞是由一种叫做天然胶水粘合在一起吗？
