Cyanobacteria of hammam faroun hot spring [Sinai-Egypt]

In this study, twenty-eight cyanobacterial taxa were identified. On the basis of temperature tolerance, it was found that the species had different thermal ranges of growth; some had a wide thermal range of growth [30 - 72C], while others were characterized by a narrow range [30 - 40C]. Some species grew only at temperature [30 or 72C] such as Merismopedia punctata and Phormidium tenue, respectively. The biocecological analysis indicated that the spring had a clean oligosaprobic character with tendency to the presence of alpha- mezosaprbic indicators such as Oscillatoria tenuis
