Challenges in determining causation in structure–function studies using molecular biological techniques
22
TL;DR: Various causation criteria improving on the Koch–Henle postulates are presented and approaches for determining cause–effect relationships are illustrated using 16S rDNA-based investigations of filaments that cause bulking and foaming in activated sludge.

Design and Evaluation of Illumina MiSeq-Compatible, 18S rRNA Gene-Specific Primers for Improved Characterization of Mixed Phototrophic Communities
TL;DR: It is found that degeneracies on the 3′ end of the current V4-specific primers impact read length and mean relative abundance, and the PCR/sequencing error is markedly higher for GC-rich members than for communities with balanced GC content.

Bacterial community dynamics in full-scale activated sludge bioreactors: operational and ecological factors driving community assembly and performance.
TL;DR: It is suggested that the ecological theories behind the Island Biogeography model and the species-area relationship were appropriate to predict the assembly of bacterial communities in these CAS bioreactors and showed that the largest bioreactor had a less dynamic but more efficient and diverse bacterial community throughout the study.
Effect of salinity on nitrification efficiency and structure of ammonia-oxidizing bacterial communities in a submerged fixed bed bioreactor

TL;DR: In this paper, the effect of salt (NaCl) on biological nitrogen removal and community structure of ammonia-oxidizing bacteria (AOB) was investigated in a submerged fixed bed bioreactor (SFBBR).

TL;DR: The influence of salt (NaCl) on bacterial and archaeal communities in a submerged fixed bed bioreactor system for the treatment of urban wastewater was determined by DGGE and 454 pyrosequencing of PCR-amplified 16S ribosomal RNA gene fragments.

Mechanisms of foam formation in anaerobic digesters
TL;DR: The available three-phase foam literature is reviewed with an emphasis on the fundamental aspects of bubble formation in AD: similarities between AD foams and other "desirable" foams, surface rheology, physico-chemical aspects of carbon dioxide in digesters, dynamics of the gas-phase, pH, alkalinity and certain relationships between these factors are discussed.

Phylogenetic identification and in situ detection of individual microbial cells without cultivation.
TL;DR: Phylogenetic analysis of the retrieved rRNA sequence of an uncultured microorganism reveals its closest culturable relatives and may, together with information on the physicochemical conditions of its natural habitat, facilitate more directed cultivation attempts.
