DACTYLOCOCCOPSIS FASCICULARIS
LEMMERMANN, 1898
Phylum: Cyanobacteria
Class: Cyanophyceae
Order: Chroococcales
Family: Chroococcaceae
Distribution: Europe, Asia
Habitat: Freshwater habitats
Description: The tiny cells of this species, which are elliptic or fusiform, mea-
sure 1-2 µm and 50 µm in width and length, respectively. The cells may be
connected by lateral walls or form a branching chain.
Compounds and activities: Celluloclast and kojizyme (carbohydrases) digests
of this species showed higher effects on superoxide anion radical scaveng-
ing, and the values were 58.1 and 56.9%, respectively. Lipid peroxidation
was signiicantly inhibited in ultralo, (carbohydrase) protamex, kojizyme,
and alcalase (proteases) digests of this species (Lee et al., 2009). The water-
soluble, antioxidative polyphenols and polysaccharides of this species have
also been reported to be potential sources for producing valuable drugs in
pharmaceutical industries.
ANABAENA DOLIOLUM
BHARADWAJA, 1935
Phylum: Cyanobacteria
Class: Cyanophyceae
Order: Nostocales
Family: Nostocaceae
Distribution: India
Habitat: Freshwater habitats, dams
Description: This ilamentous and atmospheric nitrogen-ixing species has a
symbiotic relationship with some plants.
