Freshwater samples collected from the respective type localities ofPlanctomyces bekefii Gimesi 1924 (a pond in Budapest, Hungary) and ofBlastocaulis sphaerica Henrici and Johnson 1935 (Lake Alexander, Minnesota) provided material which coincuded with the ancient descriptions of these two aquatic microorganisms. AlthoughPlanctomyces bekefii was originally described as a fungus, both organisms are seen by transmission electron microscopy to be budding and nonprosthecately appendaged prokaryotes… 

100-year-old enigma solved: identification, genomic characterization and biogeography of the yet uncultured Planctomyces bekefii.

TLDR
The results of molecular identification of this elusive bacterium, which was detected in an eutrophic boreal lake in Northern Russia, are reported and it is revealed that these bacteria only transiently surpass the detection limit, with a characteristic population peak following cyanobacterial blooms.

Metallic-Oxide encrustations of the nonprosthecate stalks of naturally occurring populations ofPlanctomyces bekefii

TLDR
Naturally occurring metallic-oxide encrustations of the multifibrillar stalks of morphotype Ia of the Blastocaulis-Planctomyces group of budding and nonprosthecately appendaged prokaryotes from two sources-a pond in Budapest, Hungary and Gebharts Teich, a fishpond in Austria-are examined by energy-dispersive X-ray spectroscopy.

Some ultrastructural features ofPlanctomyces bekefii, morphotype I of theBlastocaulis-Planctomyces group of budding and appendaged bacteria

TLDR
The ultrastructure ofPlanctomyces bekefii, a budding and appendaged bacterium, has been examined using samples obtained directly from pond water, its natural habitat, and its major appendage, the nonprosthecate stalk, is shown to have a tubular structure, with a substructure of hollow fibers.

Water samples collected in August, 1980, from a pond in Budapest, Hungary, have permitted transmission and scanning electron microscopic observations to be made ofPlanctomyces crassus Hortobágyi

History, Classification and Cultivation of the Planctomycetes

TLDR
The history of the planctomycetes is traced from their initial discovery as planktonic microcolonies in lake water, to their recognition as an evolutionarily diverse phylum encompassing three classes with a vast array of unique and unusual features.

TLDR
The history and importance of the Planctomyces bekefii species is revealed in this article.

Evolution of cellular complexity and other remarkable features in Gemmataceae : Complex bacterial lineages defy prokaryotic trends

Bacteria of the family Gemmataceae belong the phylum Planctomycetes and are remarkable because of their complex cellular architectures, previously considered to be traits exclusive to eukaryotes. T

Phylum XXV. Planctomycetes Garrity and Holt 2001, 137 emend. Ward (this volume)

The phylum Planctomycetes was circumscribed for this volume on the basis of phylogenetic analysis of 16S rRNA gene sequences; the phylum contains the class Planctomycetia.

Two Identical Genera of Budding and Stalked Bacteria: Planctomyces Gimesi 1924 and Blastocaulis Henrici and Johnson 1935

TLDR
A comparison of the characteristics of the organisms considers Blastocaulis spaerica Henrici and Johnson 1935 and Planctomyces bekefii Gimesi 1924 to be identical, which means that both organisms occur in the same habitat and at the same time.

The Blastocaulis-Planctomyces Group of Budding and Appendaged Bacteria

TLDR
The entire assemblage of these interesting budding and appendaged bacteria with prominent acellular (nonprosthecate) appendages are referred to as the “Blastocaulis-Planctomyces group” to avoid unwarranted taxonomic implications.

TLDR
Natural water samples and dilute-peptone enrichment cultures, containing budding and appendaged bacteria assigned to morphotype II of the Blastocaulis-Planctomyces group of nonprosthecately stalked prokaryotes, have been examined by transmission electron microscopy, finding unusual corniculate structures that protruded at seemingly the same loci.

TLDR
A review of the currently valid names of bacteria is conducted with the object of retaining only names for those taxa which were adequately described and cultivable, for which there was a Type, Neotype, or Reference strain available.
