16S rRNA gene amplicons from lab-scale anaerobic digesters. 16S rRNA gene amplicons from lab-scale anaerobic digesters

Lab-scale anaerobic digesters were fed with propionate for one month. Three replicates were operated without amendments (controls) and three replicates were amended with iron(II,III) oxide to stimulate direct interspecies electron transfer.

以丙酸盐为基质运行实验室规模厌氧消化反应器，持续周期为1个月。设置3组无添加剂添加的重复实验作为对照组，另外设置3组添加四氧化三铁（iron(II,III) oxide）的重复实验，以促进种间直接电子转移（direct interspecies electron transfer）过程。
