Phycoerythrins of marine unicellular cyanobacteria
The Oregon Health Authority, for example, used to recommend that lake managers test cyanobacteria
cell counts to determine whether or not a bloom would be harmful to humans.
Areas with more whitings contained iron-rich sediments, the team discovered, strengthening the argument that cyanobacteria
are the region's chief carbonate producers.
By the proliferation of the number of pathogenic microorganisms and drug-resistant cases, cyanobacteria
are of great promise for the discovery and production of new drugs .
blooms in moderately deep, stratified eutrophic lakes are characterized by the dominating Nostocales and, in contrast, shallow lakes are dominated by the family Oscillatoriaceae (Limnothrix-type) owing to their ability to use low amounts of light in turbid water.
that do not produce chlorophyll b typically possess water-soluble phycobilin pigments.
A few billion years ago cells of certain small cyanobacteria
were taken up by free-living host cells of some other bacteria in a symbiotic relationship to become the chlorophyllcontaining chloroplasts found in algae and later in plant cells.
Some of cyanobacteria
not only cause water pollution but tend to generate toxins and harm the lives of human beings and animals.
required for the bioreactor are being specially developed by incorporating plant-derived isoprene synthase genes provided by the University of Wisconsin, USA.
Specific and current examples include a vertical flat-plate bioreactor that is being designed at The University of Arizona to grow photosynthesizing cyanobacteria
to assimilate carbon dioxide ([CO.
Certain types of blue-green algae, or cyanobacteria
, produce off-flavor compounds that can give catfish a muddy or earthy taste, which keeps them from being marketable.
Marine stromatolites are the oldest known fossils, built mainly by cyanobacteria
, and dating back more than 3 billion years.
Abstract: The common occurrence of cyanobacteria
colonies attached to the exposed surfaces of the microlichen Coenogonium missouriense and the production of short filaments of cobblestone-shaped fungus cells at the apex of the association are documented.
Some species of cyanobacteria
may produce substances that are highly toxic to fish, birds, or mammals.
McNeill compares us to cyanobacteria
, which refashioned the world's atmosphere two billion years ago by excreting oxygen and increasing its presence in the air from one part per trillion to the current one-fifth.
