eubacteria

Carbonic anhydrase ( CA, EC 4.2.1.1), a zinc-containing metalloenzyme, the enzyme has been found in most organisms including animals, plants, archaebacteria, eubacteria.

碳酸酐酶（Carbonic anhydrase，CA，EC4.2.1.1）是一种含Zn~（2+）金属酶，它广泛的存在于动物、植物、细菌和微生物中。

Bacteria are divided into eubacteria and archaebacteria.

细菌分为真细菌和古细菌两类。

Bacterial Fe(ⅲ) reduction is an important pathway of bioenergy metabolism in the process of life evolution. Many kinds of archaebacteria and eubacteria are capable of reducing Fe(ⅲ) to conserve energy.

细菌Fe（Ⅲ）还原是生物进化过程中最早出现的生物能量代谢途径，多种古细菌和真细菌具有Fe（Ⅲ）还原能力。
