Request PDFDescription: Braun et al. (2005): p. 307: Unicellular cyanobacterium with bladder-like cells typically packed as duplexes, or in extracellular polymeric substance covered clumps and small chains without the ability to produce baeocystes. No growth without added combined nitrogen occurred. While requiring relatively large amounts of iron for growth (>40 uM), the isolate was shown to facilitate removal of iron from culture media.; p. 310-311: The isolate is a unicellular cyanobacterium with cells typically packed as duplexes, or in clumps or small chains (Figs. 3 and 4), covered with extracellular polymeric substance (EPS). Cells exhibit oval shape (average longitudinal diameter of 4 ± 0.77 um, and average transverse diameter of 3.3 ± 0.64 um; n = 10). Micrographs (Figs. 3-5) indicate a bladder-like shape, similar to that of Synechocystis PCC 6803 cells. Although the morphology of 5.2 s.c.l cells is reminiscent of the Synechocystis genus, a salient difference is that isolate 5.2 s.c.l has a EPS cover, visible on SEM and TEM micrographs as a 0.3-0.4 m skin-like envelope. ... EPS envelope of single 5.2 s.c.l cells may reach; ~1 um, suggesting its importance to adhesion of 5.2 s.c.l cells to surfaces. ... This finding, as well as its pronounced capacity to form biofilms on culture flask walls (data not shown), suggests that isolate 5.2 s.c.l is a sessile organism.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
