A small number of prokaryotic species have a unique physiology or ecology related to their development of unusually large size. The biomass of bacteria varies over more than 10 orders of magnitude, from the 0.2 microm wide nanobacteria to the largest cells of the colorless sulfur bacteria, Thiomargarita namibiensis, with a diameter of 750 microm. All bacteria, including those that swim around in the environment, obtain their food molecules by molecular diffusion. Only the fastest and largest… 

Figures and Tables from this paper

A centimeter-long bacterium with DNA contained in metabolically active, membrane-bound organelles

TLDR
Candidatus (Ca.) Thiomargarita magnifica is characterized, a bacterium that has an average cell length greater than 9000 micrometers and is visible to the naked eye, and contains compartmentalized genomic material and disrupts conceptions of microbial morphology.

Nano-Sized and Filterable Bacteria and Archaea: Biodiversity and Function

TLDR
Analysis of the recent data on small-sized microorganisms in the context of their taxonomic diversity and potential functions in the environment finds that many species exhibit a significant genome reduction and loss of essential metabolic pathways required for a free-living lifestyle.

Large multicellular filamentous bacteria under the oxygen minimum zone of the eastern South Pacific: a forgotten biosphere

In the soft reduced sediments of the continental shelf, below the oxygen minimum zone (OMZ) of the eastern South Pacific (ESP), peculiar microbial communities have been disclosed which include a

A Single-Cell Genome for Thiovulum sp

TLDR
Thiovulum is the second-fastest bacterium ever observed, swimming at 615 μm/s, and this genome shows that this rapid swimming motility is a result of a standard flagellar machinery that has been extensively characterized in other bacteria.

Deep-sea microorganisms and the origin of the eukaryotic cell

TLDR
The Myojin parakaryote exemplifies a potential evolutionary path between prokaryotes and eukaryotes, and strongly supports the endosymbiotic theory for the origin of mitochondria and the karyogenetic hypothesis for theorigin of the nucleus.

New communities of large filamentous sulfur bacteria in the eastern South Pacific.

  • 2007
New complex communities of morphologically diverse and sometimes abundant large, multicellular, filamentous bacteria were discovered in the oxygen-deficient, organically laden, shelf sediments under

A centimeter-long bacterium with DNA compartmentalized in membrane-bound organelles

TLDR
It is found that Thiomargarita magnifica grow orders of magnitude over theoretical limits for bacterial cell size through unique biology, display unprecedented polyploidy of more than half a million copies of a very large genome, and undergo a dimorphic life cycle with asymmetric segregation of chromosomes in daughter cells.

How much territory can a single E. coli cell control?

TLDR
This review surveys E. coli cells much longer than those which grow in nature and in usual lab cultures, including cells mutated in a single gene (metK) which are 2–4 × longer than their non-mutated parent.

Insights into the Genome of Large Sulfur Bacteria Revealed by Analysis of Single Filaments

TLDR
Comparative genomics indicates substantial horizontal gene transfer of storage, metabolic, and gliding capabilities between Beggiatoa and cyanobacteria, which enable BeGGiatoa to overcome non-overlapping availabilities of electron donors and acceptors while gliding between oxic and sulfidic zones.

TLDR
To explore the limitation imposed by diffusion, analysis is developed of diffusion processes through stirred and unstirred media, diffusion through media that contains obstacles, and the effect of size and shape.

Physiology, phylogenetic relationships, and ecology of filamentous sulfate-reducing bacteria (genus Desulfonema)

TLDR
Microscopy of organic-rich, sulfidic sediment samples of marine and freshwater origin revealed filamentous, multicellular microorganisms with gliding motility that constitute an ecologically significant fraction of the sulfate-reducing bacteria in organic- rich sediments and microbial mats.

The largest bacterium

TLDR
The results identify the symbionts of Epulopiscium fishelsoni as members of the low-(G + C) Gram-positive group of bacteria, the largest bacteria to be described so far.

TLDR
In situ CO(2) fixation rates, sulfide stimulation of incorporation, and autoradiographic studies suggest that these Beggiatoa spp.

Thioploca spp.: filamentous sulfur bacteria with nitrate vacuoles

Thioploca spp. are multicellular, filamentous, colorless sulfur bacteria inhabiting freshwater and marine sediments. They have elemental sulfur inclusions similar to the phylogenetically closely

Titanospirillum velox: a huge, speedy, sulfur-storing spirillum from Ebro Delta microbial mats.

TLDR
Details of the wall, multiflagellated termini, and large cytoplasmic sulfur globules indicate that these fast-moving spirilla are distinctive enough to warrant a genus and species designation: Titanospirillum velox genus nov., sp.

Long lag times and high velocities in the motility of natural assemblages of marine bacteria

TLDR
The motility characteristics of natural assemblages of coastal marine bacteria were examined and suggest that marine bacteria are capable of previously undescribed quick shifts in speed that may permit the bacteria to rapidly detect and keep up with positional changes in small nutrient sources.

Massive natural occurrence of unusually large bacteria (Beggiatoa sp.) at a hydrothermal deep-sea vent site

TLDR
The discovery of dense layers of filamentous sulphur-oxidizing bacteria up to 3 cm thick on the sediment surface, and up to 30 cm thick between stands of vestimen-tiferan tube worms at the Guaymas Basin hydrothermal vent site in the Gulf of California is reported.
