  • I mean, that is happening here too. But adsorption means binding to the outer surface of the cell.
  • 我是说,这个过程也在这里发生。但是吸附指的是黏在细胞的外表面。
  • And a filamentous fungus can adsorb toxic heavy metals, bind them to the surface of its enormous network of filaments, and thereby detoxify a large soil ecosystem.
  • 丝状真菌可以吸附有毒的重金属,把它们黏在它巨大的菌丝网的表面,因此除去了一个大土壤生态系统中的毒素。
  • The heavy metals are still there, but instead of leaching into the water system and contaminating the water underground,
  • 重金属还是在那儿,但是大量的这些金属也许会一直黏着在角素中,
  • large amounts of these metals may remain bound to the chitin, to the cell walls of filamentous fungi in the soil,
  • 在土壤里的丝状真菌的细胞壁中,而不是渗透到水系统中并且污染地下水,
  • and thus remain chemically inactive for as long as 30 years, perhaps longer.
  • 因此可以保持化学性质稳定长达30年,可能更长时间。
  • In fact, we can actually use the cell walls of filamentous fungi as a filter, even after the fungi are dead.
  • 事实上,即使在这些真菌死后,我们还可以把丝状真菌的细胞壁用作过滤器。
  • For example, the pharmaceutical industry grows filamentous fungi in large quantities in the lab.
  • 举个例子来说,制药行业在实验室中培育了大量的丝状真菌。
  • Like, to produce the antibiotic penicillin, the drug company grows the fungus penicillin, and after the penicillin is extracted,
  • 比如为了制造抗菌的盘尼西林,医药公司会培育盘尼西林菌群,在盘尼西林被萃取后,
