Crinalium epipsammum sp. nov.: a filamentous cyanobacterium with trichomes composed of elliptical cells and containing poly-β-(1,4) glucar (cellulose) de Winder, Ben and Stal, Lucas J. and Mur, Luuc R.,, 136, 1645-1653 (1990), doi = https://doi.org/10.1099/00221287-136-8-1645, publicationName = Microbiology Society, issn = 1350-0872, abstract= This paper describes the isolation and characterization of a new species of cyanobacterium, Crinalium epipsammum. The assignment to the genus Crinalium, first described by Crow (1927) , is based on a property which is unusual for cyanobacteria: trichomes viewed in cross-section are elliptical rather than circular. This organism was isolated from the surface layer of sandy soil of coastal dunes in The Netherlands. The organism is non-motile and drought resistant, and its cell surface is hydrophilic. The temperature optimum for growth is 25 °C. The mean DNA base composition is 33·9 mol% G + C. The cell wall is relatively thick and contains poly-β-(1,4)glucan (cellulose), which is unusual for cyanobacteria., language=, type=
