2014年10月15日 · A photomicrograph of a prepared slide showing the cyanobacteria Gloeocapsa stained pink and magnified 1000x. Individual cells are oval-shaped and surrounded by a semi-transparent (light pink) capsule or glycocalyx.

Gloeocapsa Kützing (Fig. 12A) Colonies are microscopic, usually spherical, usually aggregated in a macroscopic mucilaginous, amorphous mass that colonizes wet stony substrates and, less frequently tree bark or aquatic habitats (metaphyton or plankton).

A total of 96 taxa of cyanobacteria were found. The genus Gloeocapsa (Fig. 3) was the most widespread, occurring on 20 of the 45 monuments reported, on all substrata and represented by eight...

Gloeocapsa may be unicellular or made up of small groups of cells grouped within concentric mucilage envelopes. The individual colonies are usually spherical, microscopic, and enclosed within larger masses of mucilage. The cells are oval …

The Gloeocapsa due to occurrence of heavy sheath around is a potent biological tool for Nitrogen fixation and Calcium fixation (Gallon 1978). The obtained result would thus be very

Hanging drop technique was used to determine size shape, arrangement and motility of live bacteria in fluid media (Bisen, 2014). All the purified strains were subjected to Gram staining then slide...

Gloeocapsa (from the Greek gloia (gelatinous) and the Latin capsa (case)) is a genus of cyanobacteria. [2] The cells secrete individual gelatinous sheaths which can often be seen as sheaths around recently divided cells within outer sheaths.

View a prepared slide of Gloeocapsa. Label the following structures: gelatinous sheath, chlorophyll, colonies. Follow this link to observe a live culture of Gloeocapsa under the microscope.

Gloeocapsa strain NS4, a cyanophyte (cyanobacterium) which grows in low light levels inside cave entrances, was studied in the electron microscope by thin sectioning and freeze-etching. The cells are surrounded by a microfibrillar sheath divided by ‘dense lamellae’, which are probably an acidic mucopolysaccharide.
