Cyanobacteria (Blue-green algae)
-
A490 Anabaena Cylindrica
Filaments of bead-like cells with conspicuous, intercalary heterocysts. An excellent species for investigating cyanobacteria morphology and life cycle.
- A498 Chroococcus prescotti Mucilaginous coccoid colonies of up to 8 cells.
-
A503 Fischerella muscicola
Multiseriate, branched filaments.
- A520 Gloeocapsa sp. Colonies of simple, spherical unicells surrounded by a gelatinous sheath.
- A526 Gloeotrichia longicauda Tapering trichomes showing basal heterocysts.
- A530 Lyngbya sp. Filamentous mats of uniseriate trichomes.
- A541 Microcystis aeruginosa Colonies of compact,spherical cells; often forming seasonal ‘algal blooms’ which can be toxic to fauna.
- A547 Nodularia sp. Marine filamentous species. Shows intercalary heterocysts.
- A550 Nostoc sp. Unusual, jelly-like colonies of twisted trichomes embedded in a mucilaginous secretion. Colonies need to be crushed under a coverslip to ...
- A565 Oscillatoria animalis Simple, unbranched multicellular filament.The trichomes exhibit positive phototactic response towards light and show typical gliding movement over the substrate.
- A578 Phormidium sp. Much better than Oscillatoria for showing filamentous cells and hormogonia.
-
A583 Spirulina platensis
Large spiral trichomes an excellent demonstration species.
- A588 Stigonema sp. Shows true branching and multiseriate cell formation.
- A595 Tolypothrix sp. Tufts of trichomes, an efficient nitrogen fixer and used for ‘seeding’ paddy fields.Shows false branching.
- A591 Synechoccus leopoliensis Simple, planktonic mucilaginous,single cells. Syn.Anacystis nidulans
