Investigations on isolation and characterisation of unicellular cyanobacteria in Uzun Lake and Cernek Lake, Samsun, Türkiye

Isolation of unicellular cyanobacteria as pure cultures were carried out from the water samples collected Uzun Lake and Cernek in Kızılırmak delta, Samsun. Diluted spread onto a solid BG11 medium which was positively selective for isolated single colonies observed after incubation under continuous light. 20 composed cells selected isolates. These each isolates transferred into liquid to grow Characteristics used identification subsection form-genus Cyanobacteria they might be included. The results showed that all settled Subsectin 1 Synechococcus. To support this identification, genomic DNAs isolates, 16S rRNA gene regions amplified amplicons digested with EcoRI. Restriction fragment lengths found consistent those standard cyanobacterial strain Synechococcus sp. PCC7942. Since restriction cultural characteristics consistent, were, therefore, evaluated included Subsection
