Chlamydomonas species are widely distributed worldwide in soil and fresh water, of which Chlamydomonas reinhardtii is one of the most common and widespread. [1] C. reinhardtii is an especially well studied biological model organism , partly due to its ease of culturing and the ability to manipulate its genetics.
Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]
Protococcus C.Agardh, 1824 accepted as Chlamydomonas (synonym) Sphaerellopsis Korshikov, 1925 accepted as Vitreochlamys (synonym) [4] The family is known to be non-monophyletic, with clades not aligning to traditionally defined morphological groupings. [5]
The name Chlamydomonas nivalis is of compound Greek and Latin origin. Chlamydomonas is ultimately derived from the Ancient Greek χλαμύς (khlamús, "cloak, mantle") and μονάς (monás, "solitary"), [8] while nivalis, from the Latin nivālis, translates to 'found growing in or near snow', as this species of algae are only found associated with snow or near snowy areas.
Channelrhodopsin-1 (ChR1) and Channelrhodopsin-2 (ChR2) from the model organism Chlamydomonas reinhardtii are the first discovered channelrhodopsins. Variants that are sensitive to different colors of light or selective for specific ions (ACRs, KCRs) have been cloned from other species of algae and protists.
Chlamydomonas reinhardtii has well-studied genetics, with many known and mapped mutants and expressed sequence tags, and there are advanced methods for genetic transformation and selection of genes. [18] Sequencing of the Chlamydomonas reinhardtii genome was reported in October 2007. [19]
The D66 strain of Chlamydomonas reinhardtii, a single-celled green alga, is a cell-wall-deficient strain of C. reinhardtii that exhibits normal photosynthetic characteristics, but requires ammonia as a source of nitrogen for growth. [1]
In Chlamydomonas reinhardtii Photosystem II produces in direct conversion of sunlight 80% of the electrons that end up in the hydrogen gas. [ 20 ] In 2020 scientists reported the development of algal-cell based micro-emulsion for multicellular spheroid microbial reactors capable of producing hydrogen alongside either oxygen or CO 2 via ...
