ABSTRACT A combination of cultivation-based methods with a molecular biological approach was used to investigate whether planktonic bacteria with identical 16S rRNA gene sequences can represent distinct eco- and genotypes. A set of 11 strains of Brevundimonas alba were isolated from a bacterial freshwater community by conventional plating or by using a liquid most-probable-number (MPN) dilution series. These strains had identical 16S rRNA gene sequences and represented the dominant phylotype in… 

RETRACTED ARTICLE: Ecological Significance of Microdiversity: Coexistence Among Casing Soil Bacterial Strains Through Allocation of Nutritional Resource

Investigation of whether bacteria with identical 16S rRNA gene sequences can represent distinct eco- and genotypes and the niche overlap indices were low, suggesting that each strain occupied a different ecological niche.

Identification and Targeted Cultivation of Abundant Novel Freshwater Sphingomonads and Analysis of Their Population Substructure

The potential mechanism of niche separation in Sphingomonadaceae cannot be explained by substrate utilization alone and may be related to other traits.

Marine bacterial microdiversity as revealed by internal transcribed spacer analysis

Comparison of SAR11 clade ITS sequences with those available in GenBank indicated phylogenetic groupings based not only on depth but also on geography, potentially indicating localized differentiation or adaptation.

Low Intraspecific Diversity in a Polynucleobacter Subcluster Population Numerically Dominating Bacterioplankton of a Freshwater Pond

It is concluded that a Polynucleobacter population with an extremely low intraspecific diversity and an uneven structure numerically dominated the bacterioplankton community in the investigated habitat.

Ecotypes of Planktonic Actinobacteria with Identical 16S rRNA Genes Adapted to Thermal Niches in Temperate, Subtropical, and Tropical Freshwater Habitats

Seven strains with identical 16S rRNA genes affiliated with the Luna2 cluster were isolated from six freshwater habitats located in temperate, subtropical, and tropical climatic zones and concluded that these closely related strains represent different ecotypes adapted to different thermal niches.

Assessing Niche Separation among Coexisting Limnohabitans Strains through Interactions with a Competitor, Viruses, and a Bacterivore

Overall, the data suggest contrasting ecophysiological capabilities and partial niche separation in two coexisting Limnohabitans strains.

Assessing the Unseen Bacterial Diversity in Microbial Communities

PhyloTAGs provides a powerful way to recover the fine-level diversity within microbial communities and to study stability and dynamics of bacterial populations and to circumvent problems associated with use of protein-coding genes to survey microbial communities.

Microdiversity of extracellular enzyme genes among sequenced prokaryotic genomes

The results suggest that the capacity to produce extracellular enzymes varies at relatively fine-scale phylogenetic resolution, consistent with other traits that require a small number of genes and provides insight into the relationship between taxonomy and traits that may be useful for predicting ecological function.

How Divergent Is the Cuatro Ciénegas Oasis? Genomic Studies of Microbial Populations and Niche Differentiation

In this chapter, we describe some genomic studies that have been conducted in the CCB to describe the microdiversity of different microbial taxa. Firstly, we describe the genomic variation in the

Phenotypic and genetic analysis of Enterobacter spp. from a Brazilian oligotrophic freshwater lake.

The conception that antibiotic resistance can occur in oligotrophic freshwater lake bacteria, which has important implications for public health, is confirmed.



Multitude and temporal variability of ecological niches as indicated by the diversity of cultivated bacterioplankton.

The culturable fraction investigated in the present study constituted a relatively small fraction of the whole bacterioplankton assemblage, but already indicates that a multitude of different ecological niches must exist in the planktonic environment.

High genetic and physiological diversity of sulfate-reducing bacteria isolated from an oligotrophic lake sediment

The results indicate that a high diversity of sulfate-reducing bacterial strains can be recovered from the natural environment using the established cultivation media.

Characterization of Nodularia strains, cyanobacteria from brackish waters, by genotypic and phenotypic methods.

According to this study, two genotypes of Nodularia exist in the Baltic Sea, the non-toxic type without gas vesicles fits the description of NODularia sphaerocarpa, whereas the toxic type with gas vESicles resembles the species N. spumigena and Nodularityia baltica.

Specific detection of different phylogenetic groups of chemocline bacteria based on PCR and denaturing gradient gel electrophoresis of 16S rRNA gene fragments

The newly developed primer sets are useful for the detection of previously unknown phylotypes, for the comparison of the microbial diversity between different natural habitats, and especially for the rapid monitoring of enrichments of unknown bacterial species.

A Natural View of Microbial Biodiversity within Hot Spring Cyanobacterial Mat Communities

This review summarizes a decade of research that finds that it may be possible to understand microbial biodiversity within hot spring cyanobacterial mats by using principles similar to those developed by evolutionary ecologists to understand biodiversity of larger species.

Identification of complex composition, strong strain diversity and directional selection in local Pseudomonas stutzeri populations from marine sediment and soils.

The local populations of P. stutzeri reflect already the high genetic diversity of the global population and are influenced, to different extents, by migration, mutation and directional selection.

Phylogenetic identification and in situ detection of individual microbial cells without cultivation.

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.

Molecular microbial diversity in soils from eastern Amazonia: evidence for unusual microorganisms and microbial population shifts associated with deforestation

This report represents the first description of the microbial diversity in Amazonian soils involving a culture-independent approach and rRNA intergenic spacer analysis was used to show significant microbial population differences between a mature forest soil and an adjacent pasture soil.

The phylogenetic interrelationships of members of the genera Aeromonas and Plesiomonas were investigated by using small-subunit ribosomal DNA (rDNA) sequencing and several of the relationships derived from an analysis of the rDNA sequence data were in marked disagreement with the results of chromosomal DNA-DNA pairing experiments.
