Arthrospira
Sign in to saveArthrospira is a genus of free-floating filamentous cyanobacteria characterized by cylindrical, multicellular trichomes in an open left-hand helix. It was originally proposed in 1892 and went through a period of disuse between 1932 and 1974 due to an error perpetuated by Geitler. It contained the cultivated species used for producing spirulina until 2019, when it was found that the sequence of the type species A. jenneri was only distantly related to the cultivated species with several established genera in between, causing a new genus Limnospira to be created for them.

種 極大節螺藻 A. maxima 鈍頂節螺藻 A. platensis 等35種。 節螺藻屬（Arthrospira）是一種可自由浮動的藍綠藻。節螺藻是一種多細胞生物，有着開放左旋圓柱形的外貌。 節螺藻屬在熱帶和亞熱帶天然存在，只見於pH值高和高濃度（> 30g/L）碳酸鹽和碳酸氫鹽的湖泊裡[2][3]。 當中， 鈍頂節螺藻（A. platensis）可在非洲、亞洲及南美洲發現； 極大節螺藻（A. maxima）只在中美洲生長； 太平洋節螺藻（A. pacifica）生長於美國的夏威夷群島。 目录 1 人類使用 2 參考資料 3 參看 4 外部連結 人類使用 主条目：螺旋藻 日常的膳食補充劑螺旋藻即由本屬的兩種可食用的品種製成[3]。 參考資料 ^ Tilden, Josephine.
