“…Proteobacteria were observed to predominate in all the types of water analyzed, as could be expected from other studies on surface and drinking water (Zwart et al ., ; Williams et al ., ; Hoefel et al ., ; Eichler et al ., ; Kormas et al ., ; Kahlisch et al ., ). Other phyla with a lower prevalence in the current study, such as Actinobacteria , Cyanobacteria , Bacteroidetes , Planctomycetes , Aquificae , Acidobacteria , Chloroflexi , Verrucomicrobia , Firmicutes , Chlamydiae and Nitrospirae , have been reported in surface and drinking water (Hoefel et al ., ; Eichler et al ., ; Baik et al ., ; Poitelon et al ., ; Kormas et al ., ; Revetta et al ., ; Kwon et al ., ). Alpha ‐, Beta ‐ and Gammaproteobacteria are among the predominant bacteria in drinking and mineral water (Williams et al ., ; Manuel et al ., ; Falcone‐Dias et al ., ).…”

This study aimed to assess the influence of water treatment and distribution on the bacterial communities with particular emphasis on tap water. Samples from the water treatment plant, the bulk supply distribution system and household taps, supplied by the same drinking water treatment plant, were analyzed using culture-dependent and culture-independent methods. Water treatment imposed alterations in the composition of the bacterial community, although this effect was more evident in the cultivable bacteria rather than among the total community assessed by 16S rRNA gene-denaturing gradient gel electrophoresis (DGGE) profiling. Water disinfection, mainly chlorination, promoted a reduction on bacterial diversity and cultivability, with a shift in the pattern of cultivable bacteria from predominantly Gram-negative to predominately Gram-positive and acid-fast. Downstream of the chlorination stages, tap water, in comparison with raw water, presented higher diversity indices and cultivability percentages. From the source to the tap, members of the Alpha-, Beta- and Gammaproteobacteria were the predominant lineages identified using 16S rRNA gene-DGGE analysis. Although with a lower coverage, the DGGE-based lineage identifications were in agreement with those found using 454-pyrosequencing analysis. Despite the effectiveness of water treatment to eliminate or inactivate most of the bacteria, Proteobacteria such as Acinetobacter, Bosea and Sphingomonadaceae may successfully colonize tap water.

“…The bacterial cultures obtained by successive dilutions of the original population, to near extinction of the ability to grow, are named dilution cultures. These techniques were originally used by environmental microbiologists to explore minority populations (131,132). These scientists were also pioneers in revitalizing techniques, facilitating the mimicking of the natural environment to increase the proportions of cultured bacterial species (129,133).…”

SUMMARY Bacterial culture was the first method used to describe the human microbiota, but this method is considered outdated by many researchers. Metagenomics studies have since been applied to clinical microbiology; however, a “dark matter” of prokaryotes, which corresponds to a hole in our knowledge and includes minority bacterial populations, is not elucidated by these studies. By replicating the natural environment, environmental microbiologists were the first to reduce the “great plate count anomaly,” which corresponds to the difference between microscopic and culture counts. The revolution in bacterial identification also allowed rapid progress. 16S rRNA bacterial identification allowed the accurate identification of new species. Mass spectrometry allowed the high-throughput identification of rare species and the detection of new species. By using these methods and by increasing the number of culture conditions, culturomics allowed the extension of the known human gut repertoire to levels equivalent to those of pyrosequencing. Finally, taxonogenomics strategies became an emerging method for describing new species, associating the genome sequence of the bacteria systematically. We provide a comprehensive review on these topics, demonstrating that both empirical and hypothesis-driven approaches will enable a rapid increase in the identification of the human prokaryote repertoire.

“…Previous studies have also reported seasonal variation in bacterial and archaeal community compositions and structures in natural and constructed wetlands [27,32]. Verrucomicrobia, Proteobacteria, Bacteroidetes, Firmicutes and Actinobacteria were reported to be the dominant phyla of the planktonic bacterial communities in wetlands [29,[38][39][40][41]. In this study, although their proportions showed seasonal shifts, Proteobacteria, Firmicutes, Actinobacteria and Bacteroidetes were dominant in all samples taken from the LEW.…”

Bacterial and archaeal communities play important roles in wetland ecosystems. Although the microbial communities in the soils and sediments of wetlands have been studied extensively, the comprehensive distributions of planktonic bacterial and archaeal communities and their responses to environmental variables in wetlands remain poorly understood. The present study investigated the spatiotemporal characteristics of the bacterial and archaeal communities in the water of an artificially irrigated estuarine wetland of the Liaohe River, China, explored whether the wetland effluent changed the bacterial and archaeal communities in the Liaohe River, and evaluated the driving environmental factors. Within the study, 16S rRNA quantitative PCR methods and MiSeq high-throughput sequencing were used. The bacterial and archaeal 16S rRNA gene abundances showed significant temporal variation. Meanwhile, the bacterial and archaeal structures showed temporal but not spatial variation in the wetland and did not change in the Liaohe River after wetland drainage. Moreover, the bacterial communities tended to have higher diversity in the wetland water in summer and in the scarce zone, while a relatively higher diversity of archaeal communities was found in autumn and in the intensive zone. DO, pH and PO4-P were proven to be the essential environmental parameters shaping the planktonic bacterial and archaeal community structures in the Liaohe River estuarine wetland (LEW). The LEW had a high potential for methanogenesis, which could be reflected by the composition of the microbial communities.
