SYNECHOCOCCUS LEOPOLIENSIS
(RACIBORSKI) KOMREK
Phylum: Cyanobacteria
Class: Cyanophyceae
Order: Synechococcales
Family: Synechococcaceae
Distribution: Europe
Habitat: Freshwaters to hyposaline areas
Description: The cells of this unicellular species are small and ovoid or cylin-
drical with a size range of 0.5-2.0 µm. This species has chlorophyll
a
as the
main pigment and phycobiliproteins as the accessory pigments.
Compounds and activities: The extracts of planktonic freshwater cyanobac-
teria are known for their antibacterial properties (Ostensvik et al., 2011).
The extracts of this species possess antibacterial activity and act against
Gram- positive
Staphylococcus aureus
. Very high antibacterial activity was
detected in this species by using the carbon source galactose in combina-
tion with the nitrogen source alanine or by using arabinose with methio-
nine. Further, maximum growth and antibacterial activity of this species
were noted at 35°C and pH 8 (Noaman et al., 2004).
