bacteria capable of performing aerobic photosynthesis.
Prokaryotic, algae-like organisms, Myxophyta or Cyanophyta, that live in marine or freshwater systems. They are blue-green in color, owing to the presence of chlorophyll (green), phycocyanin (blue), and phycoerythrin (red). Most reproduce asexually, but some lack nuclei and chromatophores, and reproduce by fission.
members of the cyanobacteria (or Cyanophyta), characterised by blue-green pigmentation and a lack of cellular organisation
cyanobacteria; members of the kingdom Monera that are photosynthetic and are found in the soil and in freshwater or saltwater environments.
Bacteria containing photosynthetic pigments, often forming problematic toxic blooms.
(cyanobacteria); these bacteria-like organisms are the inventors of the kind of photosynthesis that produces free oxygen. This invention seems to have taken place only once, for the blue-green algae are also the ancestors of the chloroplasts that are found in higher plants and that are responsible for the photosynthesis on which we all depend for life.
predominantly photosynthetic prokaryotic organisms containing a blue pigment in addition to chlorophyll; occur singly or in colonies in diverse habitats; important as phytoplankton
A photosynthetic bacteria, which can occur in fresh and salt water and can produce substances toxic to animals. The blue-green is due to the presence of phycocyanin pigments. Includes Anabaena and Microcystis spp. High concentrations affect suitability of water for recreation and potable supplies.
also known as cyanobacteria. Naturally occurring, microscopic, primitive photosynthetic bacteria.
Algae that often cause problems in lakes because some produce chemicals that are toxic to animals, including humans. They often form thick floating mats of blue-green scum as they die.
an ancient order of algae (with characteristics of bacteria) that have become more common in water bodies due to disturbance and pollution. Some species produce toxins that can cause sickness and nerve and liver damage.
Algae of the Phylum Cyanophyta (also called Cyanobacteria), the most primitive group of algae. Blue-green algae are typified by cells without a true nucleus and with photosensitive pigments dispersed throughout the cell. Some species are capable of using nitrogen gas for metabolism, S ee also algal bloom. [Gk. cyano, blue + phyto, plant.
Blue-green algae (also called cyanobacteria) are simple, (usually) one-celled photosynthetic organisms that lack a membrane-bound nucleus (they are prokaryotic). They have a primitive, bacteria-like cell structure (lacking a nucleus and other organelles); although they have photosynthetic pigments, they lack chloroplasts (the specialized photosynthetic organelles seen in higher plants).
Algal form that may cause water to turn green, gray, or brown during late summer periods. Some forms may be toxic in large concentrations.
Naturally occurring, microscopic, primitive photosynthetic bacteria. Under certain conditions (including high nutrients, warm still water, strong sunlight into the water) they can bloom into a dense and visible growth and may become toxic.
( Aph. flos-aquae) - Super Blue Green® Algae provides essential fatty acids, proteins, complex sugars, vitamins, minerals, and essential amino acids.
Algae that are often associated with problem blooms in lakes. Some produce chemicals toxic to other organisms, including humans. They often form floating scum as they die. Many can fix nitrogen (N2) from the air to provide their own nutrient.
