Zhan et al. (2020), using DNA barcoding, found 13 different operational taxonomic units of red algae growing within freshwater aquarium stores in Taiwan. [1] [a] Staghorn algae of the genus Compsopogon may exist on aquarium substrates and can be epiphytic on slow-growing plants. [2] It can form branched, whitish-green strands up to six inches ...
These samples were maintained in a lab aquarium and G. lithophora was isolated from biofilm that occurred within the aquarium. G. lithophora are gram-negative, unicellular rods with oxygenic photoautotrophic metabolism and gliding motility. They contain chlorophyll a and phycocyanin and photosynthetic thylakoids located peripherally. Cells are ...
Chloroplasts probably evolved following an endosymbiotic event between an ancestral, photosynthetic cyanobacterium and an early eukaryotic phagotroph. [17] This event (termed primary endosymbiosis) is at the origin of the red and green algae (including the land plants or Embryophytes which emerged within them) and the glaucophytes, which together make up the oldest evolutionary lineages of ...
Although cyanobacteria are often referred to as "blue-green algae", most authorities exclude all prokaryotes, including cyanobacteria, from the definition of algae. [ 4 ] [ 19 ] The algae contain chloroplasts that are similar in structure to cyanobacteria.
Cyanobacteria cultured in specific media: Cyanobacteria can be helpful in agriculture as they have the ability to fix atmospheric nitrogen in soil. The unicellular cyanobacterium Synechocystis sp. PCC6803 was the third prokaryote and first photosynthetic organism whose genome was completely sequenced . [ 246 ]
Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in cyanobacteria, [1] red algae [2] and cryptophytes, [3] accessory to the main chlorophyll pigments responsible for photosynthesis.The red pigment is due to the prosthetic group, phycoerythrobilin, which gives phycoerythrin its red color.
Synechocystis is a genus of unicellular, freshwater cyanobacteria in the family Merismopediaceae. It includes a strain, Synechocystis sp. PCC 6803 , which is a well studied model organism . Synechocystis
Acaryochloris marina is a species of unicellular Cyanobacteria that produces chlorophyll d as its primary pigment (instead of the typically used chlorophyll a), allowing it to photosynthesize using far-red light, at 700-750 nm wavelength. [3] [4] A. marina is found in temperate and tropic marine environments.
