TLDR
It is proved that the enhancement of H(2) production was due to the ability of MECs to use a wider range of organic matter in WAS than in fermentation, and Syntrophic interactions between phylogenetically diverse microbial populations in anodophilic biofilms were found to drive the efficient cascade utilization of organic Matter in WAS.About:

Microbial community structure accompanied with electricity production in a constructed wetland plant microbial fuel cell
TL;DR: The PMFC produced a maximum current of 105 mA/m(2) by utilizing rhizodeposits as the sole electron donor without any external nutrient or buffer supplements, which demonstrates the feasibility of PMFCs in practical oligotrophic conditions with low solution conductivity.
Journal ArticleDOI
Correlating microbial community structure and composition with aeration intensity in submerged membrane bioreactors by 454 high-throughput pyrosequencing.
TL;DR: It was found that Nitrospira and Nitrosomonas were the dominant phylogenetic groups at the genus level of both reactors, and that the high ratio of NOB to AOB populations well supported the complete ammonium oxidation performance in the two reactors.
