Lake Chao, China, is highly eutrophicated and experiences recurrent dense cyanobacterial blooms. Its surface water is used as drinking water resource for Hefei city, hence the potential toxicity of those cyanobacteria was of interest. Sixteen isolated strains of Microcystis aeruginosa evidenced that non-toxic, toxic and highly toxic strains coexist in the lake. Microcystin variants within one strain ranged up to 11, the concentration up to 4.799 mg g DW(-1). Mass spectrometry analysis confirmed desmethylated microcystin variants.
中国巢湖富营养化严重，且频繁发生密集的蓝藻水华。其地表水被用作合肥市的饮用水资源，因此这些蓝藻的潜在毒性引起了人们的关注。从巢湖分离的 16 株铜绿微囊藻表明，无毒、有毒和高毒菌株共存于该湖中。同一株内的微囊藻毒素变体多达 11 种，浓度高达 4.799mg g DW(-1)。质谱分析证实了脱甲基微囊藻毒素变体的存在。
