Figure 4

(A) Clumps of brown cyanobacterial filamments (cy) growing in a petri dish with Z8 medium. (B) Photomicrograph of the cyanobacterial strain CYPBD1, closely related to the cyanobacterium Pseudoscillatoria coralii (FJ210722) and Roseofilum reptotaenium (HM048872), isolated from pure cultures. Note the pointed terminal cells called calyptra (cal). (C) Neighbour-joining phylogenetic tree showing the relatedness of the strains CPPORBBD1, CPPORBBD2, CPPORBBD3, and CPPORBBD4 with reference cyanobacterial strains. Numbers at each node are bootstraps values (%) obtained after 1,000 iterations.
