Inhibition of anaerobic digestion process: A review
TL;DR: This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes and indicates that co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before an aerobic digestion can significantly improve the waste treatment efficiency.

TL;DR: In this article, a metatranscriptomic analysis of methanogenic aggregates from a brewery wastewater digester, coupled with fluorescence in situ hybridization with specific 16S rRNA probes, revealed that Methanosaeta species were the most abundant and metabolically active methanogens.
Journal ArticleDOI
Dissimilatory Metal Reduction
TL;DR: Microorganisms can enzymatically reduce a variety of metals in metabolic processes that are not related to metal assimilation, including technetium, vanadium, molybdenum, gold, silver, and copper, but reduction of these metals has not been studied extensively.
Journal ArticleDOI
Reviewing the anaerobic digestion of food waste for biogas production
TL;DR: In this paper, the authors reviewed the characteristics of food waste, the principles of anaerobic digestion, the process parameters, and two approaches (pretreatment and co-digestion) for enhancing AD in food waste.

Promoting direct interspecies electron transfer with activated carbon
Fanghua Liu,Amelia-Elena Rotaru,Pravin Malla Shrestha,Nikhil S. Malvankar,Kelly P. Nevin,Derek R. Lovley +5 more
TL;DR: The results demonstrate that GAC can promote DIET and suggest that stimulation of metabolism in methanogenic digesters can be attributed, at least in part, to the high conductivity of GAC providing better interspecies electrical connections than those that can be forged biologically.
