Examples of cyanobacteria: Nostoc, Oscillatoria, Spirulina, Microcystis, Anabaena.

What is a pure axenic culture?

A pure (or axenic) culture is a population of cells or multicellular organisms growing in the absence of other species or types. A pure culture may originate from a single cell or single organism, in which case the cells are genetic clones of one another.

Which media used for isolation of cyanobacteria?

A method employing nutrient saturated glass fiber filters allowed the isolation of the same numbers of cyanobacteria from freshwater as were obtained with medium solidified with agar, while providing a 2- to 15-fold reduction in the number of accompanying heterotrophic bacteria.

Is E coli a cyanobacteria?


Is spirulina algae or bacteria?

Spirulina are classified as cyanobacteria, or blue-green algae. These are multicellular, symbiotic and filamentous blue-green microalgae having symbiotic bacteria which fixes nitrogen from air.

Why is axenic culture important?

Axenic cultures are important in genetic, biochemical, physiological and taxonomic studies. However, the use of Arthrospira spp. in biochemical and genetic studies has been limited due to the difficulties in obtaining axenic cultures (Vonshak 1997).

What parts of the body are axenic?

What is BG11 medium?

BG11 Broth is a universal medium for the cultivation and maintenance of blue green algae (cyanobacteria).

What bacteria uses CO2?

The most famous bacteria—Escherichia coli—can now eat carbon dioxide. After scientists evolved strains and performed several checks, they confirmed E. coli can consume carbon dioxide to grow, just like plants do.
