The phycobilisome components (phycobiliproteins) are responsible for the blue-green pigmentation of most cyanobacteria. [77] The variations on this theme are due mainly to carotenoids and phycoerythrins that give the cells their red-brownish coloration. In some cyanobacteria, the color of light influences the composition of the phycobilisomes.
Klamath AFA is a blue-green algae that has been harvested wild from Upper Klamath Lake since the 1980s and used as a dietary supplement. [2] [3] Genome sequencing distinguished and named this isolate as Aphanizomenon flos-aquae MDT14a, [4] [5] distinct from other varieties of Aphanizomenon flos-aquae.
The particular pigments they contain gives the cells a bluish-green color. Species of the Nostocaceae are particularly known for their nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern, cycads, and hornworts. The cyanobacteria provide nitrogen to their hosts.
A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]

The green algae (sg.: green alga) are a group of chlorophyll-containing autotrophic eukaryotes consisting of the phylum Prasinodermophyta and its unnamed sister group that contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep within the charophytes as a sister of the Zygnematophyceae.
A large amount of thermophytes are algae, more specifically blue-green algae, also referred to as cyanobacteria. This type of algae thrives in hot conditions ranging anywhere from 50 to 70 degrees Celsius, [ 3 ] [ 4 ] which other plants and organisms cannot survive in. Thermophytes are able to survive extreme temperatures as their cells contain ...
For example, in green plants, the action spectrum resembles the absorption spectrum for chlorophylls and carotenoids with absorption peaks in violet-blue and red light. In red algae, the action spectrum is blue-green light, which allows these algae to use the blue end of the spectrum to grow in the deeper waters that filter out the longer ...
