And the chitin in the cell walls of a filamentous fungus...a filament, of course, is a long thread-like structure, cells joined end to end.
而絲狀真菌的細(xì)胞壁中的角素......單纖維是一種很長的像線一樣的結(jié)構(gòu)，細(xì)胞首尾相連。
Filamentous fungi grow in soil and in decaying vegetation. And as their name implies they exist as filaments.
絲狀真菌在土壤和腐爛的植物中生長。而且正如它們的名字所指的那樣，它們以絲的形式存在。
And although regarded as microorganisms, filaments from a single fungus can fan out to occupy many square meters or even several square kilometers of forest floor.
雖然被視作微生物，但是一個(gè)單獨(dú)的真菌的菌絲可以呈扇形散開，占據(jù)森林地面上很多平方米或甚至好幾平方千米的面積。
Their vast surface area allows them to break down and take in huge amounts of nutrients,
它們巨大的表面面積允許它們分解并吸收大量的營養(yǎng)物質(zhì)，
but beyond that, the filaments also pull out of the soil a great deal of the pollution that might be in there, especially heavy metals.
不過除此之外，這些菌絲還從土壤中帶出了可能存在其中的大量污染物質(zhì)，尤其是重金屬。
And here is where chitin comes in. Like some other substances in fungal cell walls,
這就是角素的來源。和真菌細(xì)胞壁中的一些其他物質(zhì)一樣，在一個(gè)我們稱為吸附的過程中，
chitin forms strong chemical bonds to heavy metals in the environment, in a process we call adsorption.
角素形成了牢固的化學(xué)粘著劑粘結(jié)了環(huán)境中的重金屬。
Now, don’t confuse this with absorption, where a substance is absorbed into a cell, into the interior of a cell.
不要把這和吸收混淆了，吸收指的是一個(gè)物質(zhì)被吸收進(jìn)了細(xì)胞內(nèi)，進(jìn)入了細(xì)胞內(nèi)部。
