Journal ArticleDOI
Molecular assessment of complex microbial communities degrading long chain fatty acids in methanogenic bioreactors.
Diana Z. Sousa,Diana Z. Sousa,M. Alcina Pereira,M. Alcina Pereira,Hauke Smidt,Alfons J. M. Stams,M. Madalena Alves +6 more
TL;DR: Quantification by FISH and real-time PCR showed that the relative abundance of archaea increased during degradation of biomass-accumulated LCFA, providing insight into the importance and dynamics of balanced communities of bacteria and methanogens in LCFA- Accumulation/degradation cycles.
Journal ArticleDOI
Electricity-Assisted Biological Hydrogen Production from Acetate by Geobacter sulfurreducens
TL;DR: Geobacter sulfurreducens is a well-known current-producing microorganism in microbial fuel cells, and is able to use acetate and hydrogen as electron donor, and its functionality as biocatalyst for hydrogen formation at the cathode of a microbial electrolysis cell (MEC) is studied.
Journal ArticleDOI
Enrichment of thermophilic propionate-oxidizing bacteria in syntrophy with Methanobacterium thermoautotrophicum or Methanobacterium thermoformicicum
TL;DR: Results indicate that formate inhibited succinate oxidation to fumarate, an intermediate step in the biochemical pathway of propionate oxidation in cultures with M. thermoautotrophicum, showing that interspecies hydrogen transfer is the mechanism by which reducing equivalents are channelled from the acetogens to this methanogen.
Journal ArticleDOI
Microbial communities involved in anaerobic degradation of unsaturated or saturated long chain fatty acids
Diana Z. Sousa,Diana Z. Sousa,M. Alcina Pereira,M. Alcina Pereira,Alfons J. M. Stams,M. Madalena Alves,Hauke Smidt +6 more
TL;DR: Anaerobic long-chain fatty acid (LCFA)-degrading bacteria were identified by combining selective enrichment studies with molecular approaches, suggesting that these bacteria are directly involved in oleate degradation, emphasizing possible differences between the degradation of unsaturated and saturated LCFAs.
Journal ArticleDOI
The reductive glycine pathway allows autotrophic growth of Desulfovibrio desulfuricans
Irene Sánchez-Andrea,Iame Alves Guedes,Bastian V. H. Hornung,Sjef Boeren,Christopher E. Lawson,Diana Z. Sousa,Arren Bar-Even,Nico J. Claassens,Nico J. Claassens,Alfons J. M. Stams,Alfons J. M. Stams +10 more
TL;DR: Genomic, transcriptomic, proteomic and metabolomic analyses reveal that D. desulfuricans assimilates CO2 via the reductive glycine pathway, a seventh CO2 fixation pathway, which is reflected in the dependence of the autotrophic growth rate on the ammonia concentration.
