We decided to try another reducing agent, vitamin C.

我们决定试试另一种还原剂——维他命 C。

We saw that just like the other reducing agent, it in combination with isoniazid sterilized the culture.

我们看到它跟另一种还原剂相同，跟异烟肼一道将这些细胞灭活。

The important thing is that developers include reducing agents: chemicals that generally donate electrons to other compounds during a chemical reaction.

重点是显影剂里包含还原剂，它能在化学反应中给其他化合物提供电子。

Jacobs was studying whether the TB drug isoniazid was being inactivated by the presence of a particular amino acid, cysteine, which in chemical terms acts as a reducing agent, by donating electrons.

Jacobs 之前一直研究为何肺结核药物异烟肼会被氨基酸和半胱氨酸灭活，而异烟肼在化学反应中通过失电子，起到还原剂的作用。
