Halospirulina Nübel, Garcia-Pichel & Muyzer, 2000

Holotype species: Hydrocoleum subhomoeotrichum P.Sampaio

Original publication and holotype designation: Nübel, U., Garcia-Pichel, F. & Muyzer, G. (2000). The halotolerance and phylogeny of cyanobacteria with tightly coiled trichomes (Spirulina Turpin) and the description of Halospirulina tapeticola gen. nov., sp. nov. International Journal of Systematic and Evolutionary Microbiology 50(3): 1265-1277.

Description: Halotolerant, euryhaline cyanobacteria with trichomes coiled into a tight, closed helix, able to grow at salinities between 3 and 13% or above, but not at freshwater salinities. Trichome widths are typically between 1.5 and 3 µm, and helix widths vary between 4 and 6 µm. The cross walls are thin and invisible in live specimens. No sheath is visible under light microscopy. Gliding motility present, involving rotation. Found in sunlit hypersaline environments. Tolerate temperatures for growth of at least 38°C.

Origin of description: this description is from the original publication; it may have been modified slightly. The most recent alteration to this page was made on 2023-03-03 by M.D. Guiry.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
