摘 要：
2012年4月和10月在江西省鄱阳湖进行野外调查时,发现一种浮游的丝状蓝藻。通过分离纯培养,获得了6个纯化藻株。根据藻株主要形态学特征及其16S rRNA基因序列与比较,鄱阳湖这些藻株与老挝的2株Aerosakkonema funiforme较为相近,其中16S rRNA基因序列的相似度达到98%。鉴于这些藻株不同于颤藻目中其他属的藻株,因此确定为我国一水华蓝藻新记录属——气丝藻属Aerosakkonema Nanda&Watanabe2012,模式种为索状气丝藻Aerosakkonema funiforme Nanda&Watanabe 2012。

摘 要：
During a recent field survey of the water bloom forming cyanobacteria in the Poyang Lake,we collected a type of gas-vacuolated filamentous cyanobacterial.Six strains of this species were isolated and purified after the culture in the lab.The 16 S rRNA gene sequence of this species showed a high similarity(98%) with those of two strains from the Nam Ngum Reservoir of Lao People's Democratic Republic.This result,together with their morphological characteristics,suggested that these six strains were different from other Oscilatorialean cyanobacteria.Therefore this species was identified as Aerosakkonema funiforme that belonged to Aerosakkonema(Nanda & Watanabe 2012).Aerosakkonema is a new record of cyanobacteria genus in China.
