TL;DR: Two different oleate (C18:1 LCFA)-degrading anaerobic enrichment cultures were developed and it was found that LCFA conversion proceeded faster in the assays where methanogenesis was inhibited, and that it was dependent on the utilization of isethionate.

TL;DR: Sulphide production rates of sulphur-and sulphate-reducing bacteria up to 50 mg per biomass support particle per day were observed in an aerated sulphide-removal reactor with polyurethane (PUR) foam as carrier material.

TL;DR: It is indicated that bacteria that utilize sulfite and organic sulfur compounds rather than merely sulfate are relevant for human intestinal sulfur metabolism.

TL;DR: The developed RT-qPCR is a technique that can give rapid information about active processes in methanogenic granular sludge and may contribute to predict metal limitation and failure in UASB reactors.

TL;DR: An enrichment culture obtained from an aerobic granular sludge of a bench-scale anaerobic reactor degraded methanol at 65°C via sulfate reduction and acetogenesis, and approximately 30% of the meethanol was converted by acetogenic bacteria to acetate, while the remainder was degraded by these bacteria to H2 and CO2 in syntrophy with hydrogen-consuming sulfate-reducing bacteria.
