For the past 60 years Caulobacter spp. have been commonly attributed an aquatic and oligotrophic lifestyle yet are not uncommon in nutrient-rich or soil environments. This study evaluates the environmental and ecological associations of Caulobacter to reconcile past evidence, largely limited to culturing and microscopy, with currently available metagenomic and genomic data. The distribution of Caulobacter species and their characteristic adhesion-conferring genes, holdfast (hfaAB), were… 
DNA- and RNA-based bacterial communities and geochemical zonation under changing sediment porewater dynamics on the Aldabra Atoll
The remote Aldabra Atoll, Seychelles, provides the rare opportunity to study bacterial communities in pristine carbonate sediments across an entire biome. The four sampled sites cover sand with high
Evaluation of Caulobacter crescentus strain fitness at the genomic scale during growth in natural freshwater
TLDR
A transposon sequencing approach was used to globally measure the fitness consequences of gene disruption in the free-living freshwater bacterium Caulobacter crescentus and uncovered numerous hypothetical and uncharacterized genes for which disruption resulted in reduced fitness in either lake water, M2-xylose, or both.
Comparative Analysis of Ionic Strength Tolerance between Freshwater and Marine Caulobacterales Adhesins
TLDR
This study compares the adhesive holdfasts produced by the freshwater bacterium C. crescentus and a relative, the marine bacterium H. baltica, and concludes that marine Caulobacterales holdFasts have physicochemical properties that maximize binding in high ionic strength environments.
Genome-scale fitness profile of Caulobacter crescentus grown in natural freshwater
TLDR
Fitness of select mutants with defects in cell surface biosynthesis and environmental sensing were significantly more variable across days in lake water than in defined medium, presumably owing to day-to-day heterogeneity in the lake environment.
Role of Caulobacter Cell Surface Structures in Colonization of the Air-Liquid Interface
TLDR
Evidence is provided that the holdfast has physicochemical properties required for partitioning of non-motile mother cells to the air-liquid interface, which facilitates colonization of this microenvironment.
Metagenomic and Metatranscriptomic Analysis Reveals Enrichment for Xenobiotic-Degrading Bacterial Specialists and Xenobiotic-Degrading Genes in a Canadian Prairie Two-Cell Biobed System
TLDR
This study used metagenomic and metatranscriptomic techniques to characterize the microbial community in a two-cell Canadian biobed system before and after a field season of pesticide application, and was able to directly link the transcription of these genes to Pseudomonas, Oligotropha, Mesorhizobium, Rhodopseudomona, and Stenotrophomonas taxa.
Crossing Treeline: Bacterioplankton Communities of Alpine and Subalpine Rocky Mountain Lakes
From the aboveground vegetation to the belowground microbes, terrestrial communities differ between the highly divergent alpine (above treeline) and subalpine (below treeline) ecosystems. Yet, much
Potential influence of the proliferation of sediment-based diatoms on blooms of a harmful dinoflagellate Cochlodinium polykrikoides: a microcosm approach
Typhoons cause significant environmental damage in coastal areas and one of their effects is the suspension of the resting stage cells of diatoms from the surface sediment. We performed microcosm
Plant growth enhancement is not a conserved feature in the Caulobacter genus
TLDR
Genomic analyses suggested that the genomes of PGP strains maintain similar metabolic pathways compared to those of non-PGP strains, and that common genes related to PGP factors do not explain the PGP mechanisms for the Caulobacter strains the authors analyzed.
Extracellular appendages govern spatial dynamics and growth of Caulobacter crescentus on a prevalent biopolymer
TLDR
It is found that mutants lacking type IV pili or holdfast showed altered spatial patterns in microcolonies and were unable to maintain cell densities above a threshold required for maximal growth rates on the xylan polymer, whereas mutants lacking flagella showed increasedcell densities that potentially lead to increased local competition.

The genomic basis of trophic strategy in marine bacteria
TLDR
This work compares the genome sequences of two bacteria, Photobacterium angustum S14 and Sphingopyxis alaskensis RB2256, that serve as useful model organisms for copiotrophic and oligotrophic modes of life and relates the genomic features to trophic strategy for these organisms and defines their molecular mechanisms of adaptation.
Multisubstrate Isotope Labeling and Metagenomic Analysis of Active Soil Bacterial Communities
TLDR
This study coupled functional metagenomics and DNA stable-isotope probing using multiple plant-derived carbon substrates and diverse soils to characterize active soil bacterial communities and their glycoside hydrolase genes, which have value for industrial applications.
Biomass and Metabolic Activity of Heterotrophic Marine Bacteria
In the years since 1946, when ZoBell published his seminal book on marine microbiology, it has become evident that heterotrophic bacteria play an important role in nutrient cycling in the sea and
Characterization of caulobacters isolated from wastewater treatment systems
TLDR
Although the strains were distinguishable, caulobacters from the wastewater treatment systems the authors examined were relatively homogenous, were similar to characterized laboratory strains, and, with exceptions, could probably be reliably detected as a group by gene probes derived from C. crescentus strains.
A novel isolate and widespread abundance of the candidate alphaproteobacterial order (Ellin 329), in southern Appalachian peatlands.
TLDR
Next generation Illumina amplicon sequencing of small subunit rRNA genes was utilized to elucidate the microbial communities in three southern Appalachian peatlands and indicated that Ellin 329 is the third most abundant order and is most abundant near the surface layers where plant litter decomposition should be primarily occurring.

TLDR
The numbers, community composition and functional traits of bacteria present in natural wood samples under advanced decay by the white-rot basidiomycete Hypholoma fasciculare, including Proteobacteria and Acidobacteria, were investigated.
Colonization of overlaying water by bacteria from dry river sediments.
TLDR
The results suggest that the primary microbial colonizers of the water above dried sediments are passively released into the plankton and that their high growth potential is counteracted by the activity of bacterivorous protists.

TLDR
Stable isotope probing is coupled with amplicon and shotgun metagenomics to identify and characterize the functional attributes of lignin, cellulose and hemicellulose-degrading fungi and bacteria in coniferous forest soils from across North America to improve understanding of which organisms, conditions and corresponding functional genes contribute to lignocellulose decomposition.

Based on unique phenotypic traits, and phylogenetic, chemotaxonomic and DNA-DNA hybridization results, strain 7F14T should be classified as a representative of a novel species of the genus Caulobacter, for which the name CaulOBacter rhizosphaerae sp.
