Cyanobacteria - Wikipedia
WEBCyanobacteria (/ s aɪ ˌ æ n oʊ b æ k ˈ t ɪər i. ə /), also called Cyanobacteriota or Cyanophyta, are a phylum of autotrophic gram-negative bacteria that can obtain biological energy via photosynthesis.
Introduction to the Cyanobacteria - University of California …
WEBCyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact!
Cyanobacteria - an overview | ScienceDirect Topics
WEBCyanobacteria (also called blue-green algae) are an ancient group of photosynthetic microbes that occur in most inland waters and that can have major effects on the water quality and functioning of aquatic ecosystems. They include about 2000 species in 150 genera, with a wide range of shapes and sizes.

WEBSep 16, 2022 · Cyanobacteria Definition. Cyanobacteria is a group of photosynthetic bacteria widely distributed in various aquatic habitats (oceans, seas, rivers, lakes, etc.) and terrestrial habitats (e.g. moist soils). They may live singly or in colonies (by forming filaments or spheres with other cyanobacteria).

Life History and Ecology of Cyanobacteria
WEBCyanobacteria are very important organisms for the health and growth of many plants. They are one of very few groups of organisms that can convert inert atmospheric nitrogen into an organic form, such as nitrate or ammonia.

WEBCyanobacteria. This blue-green microbe called a cyanobacterium was likely the first photosynthetic organism—and it was a game changer in the story of life on Earth. Over millions of years, oxygen continued to accumulate in the atmosphere, thanks to cyanobacteria and other photosynthetic organisms.
