TL;DR: An attractive operational strategy to improve treatment performance in low‐temperature AnMBR by supporting syntrophy and methanogenesis in the membrane biofilm through controlled membrane fouling is described.

TL;DR: High oxygen affinity cytochromes, bd-type terminal oxidases, in Proteiniphilum strains were found to be closely associated with picomolar oxygen conditions, which has long been overlooked in anaerobic digestion, and energy-dependent reactive oxygen species (ROS) scavengers were ubiquitously present in different methanogenic taxa in response to replicate-specific ORP levels.

TL;DR: Investigation of the seasonal accumulation of biological foam on the activated sludge system of the Urbana-Champaign Sanitary District Northeast (UCSD-NE) wastewater treatment plant suggested the involvement of high lipid loading rates from the bypass stream in foam accumulation.

TL;DR: Results indicate that substantial levels of aceticlastic methanogens (order Methanosarcinales) were not maintained at the low solids retention times and acidic conditions of the laboratory-scale acid-phase (AP) reactor, and that methanogenesis was carried out by hydrogen-utilizing methanogen of the order Methanobacteriales.

TL;DR: This finding indicates that it was possible to develop pockets consisting almost entirely of an organism with a very limited substrate utilization spectrum in a system that was fed a synthetic wastewater containing acetate, propionate, butyrate and sucrose and that is known for its ability to develop biomass with a complex microbial community structure.
