Table 2: Morphological properties of cyanobacteria isolates.
Morphology, type of cell division, and differentiation
Unicellular, binary fission by constriction, cells sticks shaped 0.6–0.8 m wide and 1.5–2 m long, unsheathed.
Filamentous, binary fission in one plane by septum formation, no cell differentiation, ensheathed, cells barrel or cylindrical shaped 1.5–2.5 m long and 1.0–1.5 m wide.
Filamentous, binary fission in one plane by septum formation, cells round shaped 3.0–3.5 m in diameter and are able to differentiate hormogonia and intercalary heterocysts and akinetes. Vegetative trichomes have their own sheaths and are joined by colonial mucus.
Classification was performed according to Castenholz .
