Relating Anaerobic Digestion Microbial Community and Process Function [PDF]

open access: yes, 2016
Anaerobic digestion (AD) involves a consortium of microorganisms that convert substrates into biogas containing methane for renewable energy. The technology has suffered from the perception of being periodically unstable due to limited understanding of ...

ThermoPhyl : a software tool for selecting phylogenetically optimized conventional and quantitative-PCR taxon-targeted assays for use with complex samples [PDF]

open access: yes, 2011
The ability to specifically and sensitively target genotypes of interest is critical for the success of many PCR-based analyses of environmental or clinical samples that contain multiple templates.Next-generation sequence data clearly show that such ...

Repeated pulse feeding induces functional stability in anaerobic digestion [PDF]

open access: yes, 2013
Anaerobic digestion is an environmental key technology in the future bio-based economy. To achieve functional stability, a minimal microbial community diversity is required. This microbial community should also have a certain “elasticity”, i.e.

Limits of life and the habitability of Mars: The ESA space experiment BIOMEX on the ISS [PDF]

open access: yes, 2019
BIOMEX (BIOlogy and Mars EXperiment) is an ESA/Roscosmos space exposure experiment housed within the exposure facility EXPOSE-R2 outside the Zvezda module on the International Space Station (ISS).

Metabolic Adaptation of Methanogens in Anaerobic Digesters Upon Trace Element Limitation

open access: yesFrontiers in Microbiology, 2018
Anaerobic digestion (AD) is a complex multi-stage process relying on the activity of highly diverse microbial communities including hydrolytic, acidogenic and syntrophic acetogenic bacteria as well as methanogenic archaea.

Necessity of electrically conductive pili for methanogenesis with magnetite stimulation [PDF]

open access: yesPeerJ, 2018
Background Magnetite-mediated direct interspecies electron transfer (DIET) between Geobacter and Methanosarcina species is increasingly being invoked to explain magnetite stimulation of methane production in anaerobic soils and sediments.

Selenocysteine, pyrrolysine and the unique energy metabolism of methanogenic archaea [PDF]

open access: yes, 2010
Methanogenic archaea are a group of strictly anaerobic microorganisms characterized by their strict dependence on the process of methanogenesis for energy conservation.

Phase-Transition in Binary Sequences with Long-Range Correlations [PDF]

open access: yes, 2003
Motivated by novel results in the theory of correlated sequences, we analyze the dynamics of random walks with long-term memory (binary chains with long-range correlations).

Nitrogenase in the archaebacterium Methanosarcina barkeri 227 [PDF]

open access: yesJournal of Bacteriology, 1990
The discovery of nitrogen fixation in the archaebacterium Methanosarcina barkeri 227 raises questions concerning the similarity of archaebacterial nitrogenases to Mo and alternative nitrogenases in eubacteria. A scheme for achieving a 20- to 40-fold partial purification of nitrogenase components from strain 227 was developed by using protamine sulfate ...

Intermittent fasting for microbes: how discontinuous feeding increases functional stability in anaerobic digestion

open access: yesBiotechnology for Biofuels, 2018
Background Demand-driven biogas production could play an important role for future sustainable energy supply. However, feeding a biogas reactor according to energy demand may lead to organic overloading and, thus, to process failures.
