- Abstract:
- ... The role of direct interspecies electron transfer (DIET) on enhancement of methanogenesis has been studied. This mini-review updated the current researches on the potential role of DIET on enhanced performance for anaerobic digestion of organic substrates with effective strategies implemented. Since most experimental observations correlated with the DIET mechanism are yet to be consolidated, this ...

To study the impact of water saturation heterogeneity on hydrate production, a multilayer sand-filling method was used to synthesize two types of hydrate-bearing samples designated Class 2 and Class 3. The experimental results indicated that the sensible heat of ...

Replacing coenzyme F₄₃₀, an Ni(i) F₄₃₀-like cofactor derived from vitamin B₁₂ (F₄₃₀₋B₁₂) is revealed by DFT calculations to be able to catalyze methane formation in methyl-coenzyme M reductase with a barrier of 13.3 kcal mol⁻¹, demonstrating the correctness of the route starting from vitamin B₁₂. The structure–activity relationships of F₄₃₀ and F₄₃₀₋B₁₂ (especially the roles of the F ring) are dis ...

- Abstract:
- ... Biomethanation of the syngas from biomass gasification provides an alternative method for production of biofuel and chemicals. CO in syngas plays a key role in biomethanation of syngas, as it is both a substrate and an inhibitor of certain methanogenesis processes. In this study, CO biomethanation by using a mixture of N₂ and CO as the gas substrate, was investigated with the help of 5 adapted ana ...
