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.

Gloeocapsa, genus in the order Chroococcales, phylum Cyanophyta (blue-green algae), with either single or clustered cells enclosed in concentric layers of mucilage. Largely terrestrial, they are found on rocks or moist soils.

Gloeocapsa cells have similar osmiophilic bodies with a less regular shape (Paran et al., 1971). Besides the dense osmiophilic globules there are other positively or negatively stained bodies in the protoplast which appear mainly in the centroplasm.

Gloeocapsa magma is a species of bacteria in the Gloeocapsa genus of cyanobacteria, an ancient line of photosynthesizing bacteria, which photolyze water generating oxygen gas. Ancient cyanobacteria were ancestral to the chloroplasts of all plants on earth.

Gloeocapsa sp. produces MAAs proportional to exposure to UV light (Garcia-Pichel et al. 1993). Habitat: Mostly on wet rocks, and less often on moist soil and other terrestrial surfaces, and in freshwater plankton .

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 …

2024年10月26日 · Blue-green algae, or Gloeocapsa magma, is a cyanobacterium that travels through the air, often spreading from one roof to another throughout a neighborhood. This type of algae thrives in warm, wet climates and can quickly cover large areas.

2022年9月12日 · Gloeocapsa (Gr. gloia glue, capsa a box) is a terrestrial or sub-aerial alga generally found on damp soils, wet rocks, banks, etc., as well as in the water reservoirs and lakes. Some species are marine; they occur as a black encrusting film on rocks at the upper limit of the high-tide mark in the littoral zone.
