The phylum Streptophyta comprises all land plants and six monophyletic groups of charophycean green algae (Mesostigmatales, Chlorokybales, Klebsormidiales, Zygnematales, Coleochaetales, and Charales). Phylogenetic analyses of four genes encoded in three cellular compartments suggest that the Charales are sister to land plants and that charophycean green algae evolved progressively toward an inc...
The extracts from 30 species of the green algae were examined for hemagglutination activity with a variety different animal and human erythrocytes which untreated treated enzymes. Almost all showed at least toward one type tested. Strong was detected in 5 Chlorophyta (Anadyomene plicata, Avrainvillea erecta, Boodlea struveoides, Halimeda velasquezii discoidea) enzyme-treated rabbit sheep erythr...
In vitro the antibacterial activity of the Acetone, Methanol and Ethanol extracts of three marine algae from Ennore beach near Chennai (coast of Tamil Nadu) were tested. The test organism includes Gram negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Gram positive bacteria such as Staphylococcus aureus. In this study, agar well diffusion test techniq...
Symbiosis of green algae with protozoa and invertebrates has been studied for more than 100 years. Endosymbiotic green algae are widely distributed in ciliates (e.g. Paramecium, Stentor, Climacostomum, Coleps, Euplotes), heliozoa (e.g. Acanthocystis) and invertebrates (e.g. Hydra, Spongilla), and have traditionally been identified as named or unnamed species of Chlorella Beij. or Zoochlorella K...
