束絲藻屬(学名:Aphanizomenon)隶属于蓝菌门念珠藻目念珠藻科,是一種在淡水生活的浮游丝状藻类,能引發水華[1][2],但亦可調節水體的浮力[3]。
束絲藻屬並非所有品種均可食用,一來因為可能有毒[4](例如纤细束丝藻和依沙束丝藻會产生麻痹性贝毒毒素[1]),二來可能因為水體本身就已污染,吃用了會連同污染物一起吃進肚裡。
特征
束丝藻的特征是丝状体末端细胞渐细或成发状,延伸成无色的细胞[1]。可在水中透過滑翔來移動。
物種
以下為常見之束丝藻品種[1]:
- Aphanizomenon aphanizomenoides (Forti 1911) Horecká and Komárek 1979
- Aphanizomenon capricorni Cronberg and Komárek 2004
- Aphanizomenon favaloroi Otaño 2012
- Aphanizomenon flexuosum Komárek & Kovácik
- 水华束丝藻 Aphanizomenon flosaquae Ralfs ex Bornet & Flahault
- 纤细束丝藻 Aphanizomenon gracile Lemmerm.,柔细束丝藻
- Aphanizomenon holsaticum Richter
- Aphanizomenon hungaricum Komárk.-Legn. & Mátyás, 1995
- 依沙束丝藻 Aphanizomenon issatschenkoi (Usachev 1938) Proshkina-Lavrenko 1968[5]
- Aphanizomenon klebahnii Pechar and Kalina, 1994[6]
- Aphanizomenon manguinii Bourr.
- Aphanizomenon ovalisporum Forti 1911
- Aphanizomenon paraflexuosum Watanabe 1991
- Aphanizomenon schindleri Kling et al. 1994
- Aphanizomenon skujae Komárk.-Legn. & Cronberg, 1992
- Aphanizomenon tropicale Horecká and Komárek 1979,也拼作'Aphanizomenon tropicalis
- Aphanizomenon volzii (Lemmermann 1905) Komárek 1984
- Aphanizomenon yezoense M.Watan., 1911
當中有研究透過比對16SrRNA和Rubisco两个基因,表明水华束丝藻和纤细束丝藻具有较高的亲缘关系,其相似性分别为 99%和99%,而依沙束丝藻亲缘关系较远,相似性分别只有96%和93-94%[1]。
