TL;DR: The functional community structures (diversity and relative abundance) of major trophic groups were quantitatively analyzed by MAR-FISH and the hitherto unknown metabolic functions of Spirochaeta and candidate phylum of TM7 as well as Synergistes were found to be glucose and acetate utilization.

TL;DR: It is the first time to report the acetate-utilizing activity of uncultured bacteria belonging to Synergistes group 4 and its competitive significance to acetoclastic methanogen, Methanosaeta.

TL;DR: These phylogenetically and functionally diverse, to some extent functionally redundant, active POB communities were dynamically responding to the periodical changes in propionate concentration.

TL;DR: The results indicated that glucose was predominately degraded to CH(4) and CO(2) by glucose-degrading Propionibacterium and Olsenella that are belonging to the phylum Actinobacteria, propionate- Degrading Smithella and Syntrophobacter, and acetate-degRading Methanosaeta and Synergistes group 4 in this anaerobic sludge.

TL;DR: In this article, the status of river water quality are assess using STORET method, based on (five) parameters, STORET value showed that in Brantas River, Pagerluyung monitoring point had the worst quality relatively compared to other monitoring point in BR with exceeding copper, lead and tin compared to the stream standard in East Java Provincial Regulation No. 2 in 2008.
