TL;DR: In this article, the effect of low temperature pre-treatment on the efficiency of thermophilic anaerobic digestion of primary and secondary waste sludge was investigated, and the results suggest that a short period (9 h) low-temperature pretreatment should be enough to enhance methane production through thermophilicity of sludge.

TL;DR: In this article, the results of an experimental methane fermentation study on untreated, NaOH and hydrothermal pretreated substrates of wheat straw were presented, which resulted in specific methane and biogas production yields of 78.4% and 188.4%, respectively.

TL;DR: This review summarizes the biochemical and metabolic background of methanogenesis as well as the latest technical applications of meethanogens to give a sufficient overview over the topic to both, biologists and engineers handling biological or bioelectrochemical meethanogenesis.
Abstract: Since fossil sources for fuel and platform chemicals will become limited in the near future, it is important to develop new concepts for energy supply and production of basic reagents for chemical industry. One alternative to crude oil and fossil natural gas could be the biological conversion of CO2 or small organic molecules to methane via methanogenic archaea. This process has been known from biogas plants, but recently, new insights into the methanogenic metabolism, technical optimizations and new technology combinations were gained, which would allow moving beyond the mere conversion of biomass. In biogas plants, steps have been undertaken to increase yield and purity of the biogas, such as addition of hydrogen or metal granulate. Furthermore, the integration of electrodes led to the development of microbial electrosynthesis (MES). The idea behind this technique is to use CO2 and electrical power to generate methane via the microbial metabolism. This review summarizes the biochemical and metabolic background of methanogenesis as well as the latest technical applications of methanogens. As a result, it shall give a sufficient overview over the topic to both, biologists and engineers handling biological or bioelectrochemical methanogenesis.

TL;DR: Inoculum acclimation not only accelerated the production of biogas, but also increased the extent of the ultimate mesophilic biodegradation of MW irradiated WAS (after 15-27 d).
