Journal ArticleDOI
Desulforhabdus amnigenus gen. nov. sp. nov., a sulfate reducer isolated from anaerobic granular sludge
TL;DR: From granular sludge of an upflow anaerobic sludge bed (UASB) reactor treating paper-mill wastewater, a sulfate-reducing bacterium (strain ASRB1) was isolated with acetate as sole carbon and energy source and characterized as a new genus and species: Desulforhabdus amnigenus.
Journal ArticleDOI
Effect of humic acid on anaerobic digestion of cellulose and xylan in completely stirred tank reactors: inhibitory effect, mitigation of the inhibition and the dynamics of the microbial communities.
Samet Azman,Ahmad F. Khadem,Ahmad F. Khadem,Caroline M. Plugge,Alfons J. M. Stams,Sabina Bec,Grietje Zeeman +6 more
TL;DR: Microbiological analyses showed that the relative abundance of hydrolytic/fermentative bacterial groups such as Clostridiales, Bacteroidales and Anaerolineales was significantly lowered by the presence of HA, whereas Methanosaetacea was not affected and mostly hydrogenotrophic methanogens were negatively affected.
Journal ArticleDOI
Activity and viability of methanogens in anaerobic digestion of unsaturated and saturated long-chain fatty acids.
Diana Z. Sousa,Andreia Filipa Ferreira Salvador,Juliana Ramos,Ana P. Guedes,S. G. Barbosa,Alfons J. M. Stams,Alfons J. M. Stams,M. Madalena Alves,Maria Alcina Pereira +8 more
TL;DR: Overall, oleate had a more stringent effect on methanogens than saturated LCFA, and the degree of tolerance to LCFA was different among distinct species of methanogen.
Journal ArticleDOI
A genomic view on syntrophic versus non-syntrophic lifestyle in anaerobic fatty acid degrading communities.
Petra Worm,Jasper J. Koehorst,Michael Visser,Vicente T. Sedano-Núñez,Peter J. Schaap,Caroline M. Plugge,Diana Z. Sousa,Alfons J. M. Stams +7 more
TL;DR: In this article, the authors study from a genome perspective why some micro-organisms are able to grow in syntrophy with methanogens and others are not, and identify two domains with a currently unknown function seem to be associated with the ability of syntrophic growth.
Journal ArticleDOI
Pathways of Sulfide Oxidation by Haloalkaliphilic Bacteria in Limited-Oxygen Gas Lift Bioreactors
Johannes B.M. Klok,Pim L. F. van den Bosch,Cees J.N. Buisman,Alfons J. M. Stams,Karel J. Keesman,Albert J.H. Janssen,Albert J.H. Janssen +6 more
TL;DR: It is proposed that the bacteria reduce NAD(+) without direct transfer of electrons to oxygen and that this is most likely the main route for oxidizing sulfide to elemental sulfur which is subsequently oxidized to sulfate in oxygen-limited bioreactors, and is called the limited oxygen route (LOR).
