Review on Mechanisms of Iron Accelerants and Their Effects on Anaerobic Digestion

Agriculture
Anaerobic digestion is an important technology for energy recovery from organic waste. However, methanogenesis is restricted by some barriers, such as the low-speed bottleneck of interspecies electron transfer (IET), the low hydrogen partial pressure ...

Thermodynamics of interspecies electron transfer: from syntrophy to parasitism

, 2017
Interspecies Electron Transfer (IET) is a mechanism that allows energetic coupling between two microorganisms. It plays a key role in a wide range of environmental and biotechnological microbial ecosystems and stimulation of Direct Interspecies Electron Transfer (DIET) appears as an attractive way to boost anaerobic digestion.
