TL;DR: It is concluded that Methylophilales bacteria are the dominant denitrifiers in the SBR system and likely are important denitRifiers in full-scale methanol-fed Denitrifying sludges.

TL;DR: It is suggested that the impact of bacteria on activated sludge subjected to intermittent acetate supplementation should be assessed prior to the widespread use of acetate in the wastewater industry to enhance denitrification.

TL;DR: Based on the laboratory-scale investigations, detachment of pipe wall biofilms due to cell death or flow dynamics could release the entrapped Fe and Mn into the bulk water, which could lead to a discoloured water event and managing biofilm growth on drinking water pipelines should be considered by water utilities to minimize accumulation of Fe andmn in distribution networks.

TL;DR: This study describes for the first time a single electroactive biofilm that acts as a bioanode and a biocathode, alternately catalyzing anodic acetate oxidation and cathodic denitrification and indicates that the ano-cathodophilic biofilm denitrified autotrophically using the electrode (-200 to -600 mV Ag/AgCl) as a direct electron donor.

TL;DR: The study for the first time associates chloramine residuals and nitrification metabolites to different microbial communities, which is expected to re-direct the focus from nitrifiers to heterotrophic bacteria, which the authors believe could hold the key towards developing a control strategy that would enable better management of chloramines residuals.
