A review is given of the properties of the hydrogenase present in Rhizobium bacteriods together with a discussion and evidence of the function of the enzyme in relationship to nitrogen fixation. The efficiency with which nodules fix nitrogen i.e. the amount of hydrogen evolved as a ratio of the total electron flow through nitrogenase, is considered and the recycling of hydrogen is discussed. Attention is drawn to recent work, in which plants which have nodules containing hydrogenase have been shown to fix more nitrogen and increase more in dry matter than plants with nodules without hydrogenase.
本文综述了根瘤菌中存在的氢化酶的特性,并讨论了该酶在固氮作用中的功能及相关证据。文中考虑了根瘤固氮的效率,即作为通过固氮酶的总电子流之比所释放的氢气量,并讨论了氢气的循环利用。文中还提到了最近的研究工作,其中含有氢化酶的根瘤植物比不含氢化酶的根瘤植物表现出更高的固氮能力和干物质增加量。
