Sustained H₂ photoproduction is demonstrated in green algae under a train of strong white light pulses interrupted by longer dark phases. The devised protocol relies on the presence of the [FeFe]-hydrogenase in algal chloroplasts, which is activated within a few seconds after the establishment of anaerobiosis. H₂ photoproduction proceeds for up to 3 days with the maximum rate occurring in the first 6 hours.

莱茵衣藻（Chlamydomonas reinhardtii） 持续有效生产H _2的新方法†

在绿藻中，一列强烈的白光脉冲被较长的暗相打断，显示出持续的H ₂光产生。设计的方案依赖于藻类叶绿体中[FeFe]氢化酶的存在，该酶在厌氧菌建立后的几秒钟内被激活。H _2的照相过程最多进行3天，最大速率发生在最初的6小时内。
