The ecology and biotechnology of sulphate-reducing bacteria
Sulphate-reducing bacteria (SRB) are anaerobic microorganisms that use sulphate as a terminal electron acceptor in, for example, the degradation of organic compounds. They are ubiquitous in anoxicExpand
Distinctive properties of high hydrogen producing extreme thermophiles, Caldicellulosiruptor saccharolyticus and Thermotoga elfii
Growth and hydrogen production by two extreme thermophiles during sugar fermentation was investigated. In cultures of Caldicellulosiruptor saccharolyticus grown on sucrose and Thermotoga eli grown onExpand
Anaerobic digestion.
TLDR
Compared to the raw animal slurries AD digested material is significantly less odorous, and has lower organic pollution potential, which ultimately has water quality benefits. Expand
Substrate and product inhibition of hydrogen production by the extreme thermophile, Caldicellulosiruptor saccharolyticus.
TLDR
Substrate and product inhibition of hydrogen production during sucrose fermentation by the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus was studied and ionic strength was responsible for inhibition. Expand
Methanogenesis from acetate: a comparison of the acetate metabolism in Methanothrix soehngenii and Methanosarcina spp.
Abstract Acetate is the precursor of approximately two-thirds of the methane produced in anaerobic bioreactors. Only two genera of methanogenic archae are known to use acetate as sole energy source:Expand
Electron transfer in syntrophic communities of anaerobic bacteria and archaea
TLDR
The transfer of hydrogen and formate between bacteria and archaea that helps to sustain growth in syntrophic methanogenic communities is reviewed and the process of reverse electron transfer is described, which is a key requirement in obligately syntrophic interactions. Expand
Purification and Characterization of (Per)Chlorate Reductase from the Chlorate-Respiring Strain GR-1
TLDR
The purification and characterization of the key enzyme of the reductive pathway, the chlorate and perchlorate reductase is described and the resemblance of the enzyme to nitrate reductases, formate dehydrogenases, and selenate reduCTase is discussed. Expand
Syntrophism among Prokaryotes
TLDR
Want to understand how microorganisms act in natural systems requires the realization that microorganisms don’t usually occur as pure cultures out there, but that every single cell has to cooperate or compete with other microor macroorganisms. Expand
Utilisation of biomass for the supply of energy carriers
TLDR
This mini-review of several fermentation processes is discussed, starting with the most advanced process of ethanol production, followed by methane production, an established process for waste water purification which is gaining more attention because of the inherent energy production. Expand
Syntrophic butyrate and propionate oxidation processes: from genomes to reaction mechanisms.
In anoxic environments such as swamps, rice fields and sludge digestors, syntrophic microbial communities are important for decomposition of organic matter to CO2 and CH4 . The most difficult step isExpand
