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，专业的肥者可能肥中再加入一些木屑或者纸品，因为它们含有大量木素，一种完全不含氮的坚韧的植物细胞壁成分。

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

植物的木素和纤维素，软体动物和珊瑚礁富含钙的贝壳，以及像我们这样的矿物骨骼。

Hardwoods used in BBQ smoke have lots of cellulose and lignin.

Bacteria can still eat lignin-packed materials — so they just slow down those overly- enthusiastic microbes.

细菌也可以分解含有木素的物，从而可以让这些过于活跃的微生物下来。

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

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

就像，我本想弯曲，但木素，它却硬是不让，非得挡在我面前。

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的纸盒，可以用作食品容器，然后进行回收。第三个是找到木素的用途，木素是制浆过程中的副产品，目前还没有很好的利用方法。

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，这些种子中的木素、锌、硒、维生素E以及必需脂肪酸可能影响雌激素和孕酮的活性，即影响你月经周期中的激素变化。

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， 是因为木素，一种构成木材的化学物， 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， 尽管它们在瘤胃中的活体占比只有大约5%，但它们能够分解纤维素内部木素之间的特定化学键。

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，许多能够分解坚韧的木素并释放二氧化碳的微生物尚未进化出来。

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.

构成木材的纤维素和木素分子中的所有化学键都含有能量，其中一些键可以被打破，从而释放出这些能量。

In order for termites and a few other insects to digest wood, they had to turn those independently-living lignin-breaking microbes into gut-living lignin-breaking microbes.

为了让白蚁和其他一些昆虫消化木材，它们必须将那些独立生活的木素分解微生物转变为肠道生活的木素分解微生物。

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， 富含木素，这是一种坚硬的化合物网络， 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.

它们分解木素和纤维素， 这是最耐腐蚀的碳形式，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.

该计划是开发利用木素制造阳极碳的方法，木素是一种存在于植物细胞壁中的天然聚合物。

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，一个由木素构成的环，也就是那种像木头一样的物，渗入细胞壁中。
