摘要
浮游蓝丝藻是水华蓝藻的常见种属,但对其生长和产毒特性认识不多本文首次对我国水体中的浮游蓝丝藻进行了研究.从广东省一重要供水水库中分离到一株丝状蓝藻,经形态特征鉴定为阿氏浮游蓝丝藻,并在不同的光照和温度下对该藻株进行了培养.结果表明,适合于该藻生长的光强和温度分别为20μmol/(m^2·s)和30℃;该藻株具有mcyE基因,能产生微囊藻毒素MCRR,产量为0.06μg/mg(DW).
Planktothrix agardhii, a filamentous cyanobacterial species, is one of the major waterbloom-forming cyanobacteria and has been widely founded in lakes and reservoirs. However, its toxin-producing characteristics in the strains was never reported in China. In this paper, a strain Planktothrix agardhii SK3 was isolated from a reservoir of Guangdong Province and cultured in a gradient of light intensity and water temperature to investigate its growth characteristics. Results showed that 20μmol/（m2.s） and 30℃ were optimal for its growth. The SK3 strain had microcystin synthetase gene-mcyE and was able to produce 0. 06μg/mg （ dry weight） microcystin-RR.
