In the past decades, considerable attention has been directed toward anaerobic digestion
(AD), which is an effective biological process for converting diverse organic wastes into …

The development and utilization of bioenergy from various biomass can effectively reduce
our dependence on fossil fuels and mitigate greenhouse gas emissions. The dry anaerobic …

Microbial electrochemical techniques describe a variety of emerging technologies that use
electrode–bacteria interactions for biotechnology applications including the production of …

H 2 production by dark fermentation using mixed cultures has been studied intensively
during the last two decades, and its feasibility has been demonstrated. Different substrates …

Dark fermentative bio-hydrogen production is not commercially exploited due to several
factors hindering its production, making the process unfeasible on large scale. This study …

One of the most important biotechnological challenges is to develop environment friendly
technologies to produce new sources of energy. Microbial production of biohydrogen …

This paper is a comprehensive review of H 2 consumption during anaerobic mixed culture H
2 dark fermentation with a focus on homoacetogenesis. Homoacetogenesis consumed from …

The degradation of the natural environment and the energy crisis are two vital issues for
sustainable development worldwide. Hydrogen is considered as one of the most promising …

Fatty acids and alcohols are key intermediates in the methanogenic degradation of organic
matter, eg, in anaerobic sewage sludge digestors or freshwater lake sediments. They are …

Surplus energy out of fluctuating energy sources like wind and solar energy is strongly
increasing. Biological hydrogen (H 2) methanation (BHM) is a highly promising approach to …
