Effect of sulfate on carbon monoxide conversion by a thermophilic syngas-fermen...
Alves, J. I.; Visser, Michael; Arantes, Ana Luísa; Nijsse, Bart; Plugge, Caroline M.; Alves, M. M.; Stams, Alfons Johannes MariaA syngas-degrading enrichment culture, culture T-Syn, was dominated by a bacterium closely related to Desulfofundulus australicus strain AB33T (98% 16S rRNA gene sequence identity). Culture T-Syn could convert high CO concentrations (from pCO 34 kPa to pCO 170 kPa), both in the absence and in the presence of sulfate as external electron acceptor. The products formed from CO conversion were H2 and acetate. With ...
Long-chain fatty acids degradation by desulfomonile species and proposal of can...
Alves, J. I.; Salvador, Andreia Filipa Ferreira; Carvalho, Ana Rita Castro; Zheng, Ying; Nijsse, Bart; Atashgahi, Siavash; Sousa, Diana Zita MachadoMicrobial communities with the ability to convert long-chain fatty acids (LCFA) coupled to sulfate reduction can be important in the removal of these compounds from wastewater. In this work, an enrichment culture, able to oxidize the long-chain fatty acid palmitate (C16:0) coupled to sulfate reduction, was obtained from anaerobic granular sludge. Microscopic analysis of this culture, designated HP culture, reve...
Organohalide-respiring Desulfoluna species isolated from marine environments
Peng, Peng; Goris, Tobias; Lu, Yue; Nijsse, Bart; Burrichter, Anna; Schleheck, David; Koehorst, Jasper J.; Liu, Jie; Sipkema, DetmerThe genus Desulfoluna comprises two anaerobic sulfate-reducing strains, D. spongiiphila AA1T and D. butyratoxydans MSL71T, of which only the former was shown to perform organohalide respiration (OHR). Here we isolated a third strain, designated D. spongiiphila strain DBB, from marine intertidal sediment using 1,4-dibromobenzene and sulfate as the electron acceptors and lactate as the electron donor. Each strain...
A benzene-degrading nitrate-reducing microbial consortium displays aerobic and ...
Atashgahi, Siavash; Hornung, Bastian; van der Waals, Marcelle J.; da Rocha, Ulisses Nunes; Hugenholtz, Floor; Nijsse, Bart; Molenaar, DouweIn this study, we report transcription of genes involved in aerobic and anaerobic benzene degradation pathways in a benzene-degrading denitrifying continuous culture. Transcripts associated with the family Peptococcaceae dominated all samples (2136% relative abundance) indicating their key role in the community. We found a highly transcribed gene cluster encoding a presumed anaerobic benzene carboxylase (AbcA a...
Unravelling the one-carbon metabolism of the acetogen Sporomusa strain An4 by g...
Visser, Michael; Pieterse, Mervin M.; Pinkse, Martijn W. H.; Nijsse, Bart; Verhaert, Peter D. E. M.; Vos, Willem M. de; Schaap, Peter J.The Sporomusa genus comprises anaerobic spore-forming acetogenic bacteria that stain Gram-negative. Sporomusa species typically grow with one-carbon substrates and N-methylated compounds. In the degradation of these compounds methyltransferases are involved. In addition, Sporomusa species can grow autotrophically with H2 and CO2, and use a variety of sugars for acetogenic growth. Here we describe a genome analy...
Perchlorate and chlorate reduction by the Crenarchaeon Aeropyrum pernix and two...
Liebensteiner, Martin G.; Pinkse, Martijn W. H.; Nijsse, Bart; Verhaert, Peter D. E. M.; Tsesmetzis, Nicolas; Stams, Alfons Johannes MariaThis study reports the ability of one hyperthermophile and two thermophilic microorganisms to grow anaerobically by the reduction of chlorate and perchlorate. Physiological, genomic and proteome analyses suggest that the Crenarchaeon Aeropyrum pernix reduces perchlorate with a periplasmic enzyme related to nitrate reductases, but that it lacks a functional chlorite-disproportionating enzyme (Cld) to complete th...
