假鱼腥藻生长及产异味能力实验数据集（2022年）

通过对水源地筛选出的关键产异味藻株-假鱼腥藻进行生长能力和产异味能力测定，在不同氮浓度条件下，以13天为生长周期，结合干重、细胞数、叶绿素指标探索其胞外MIB、胞内MIB的影响，结果显示高氮浓度下假鱼腥藻的生长速率更快，且产异味能力也越大，最大异味物质（2-MIB）可以达到161μg/L。

Growth and odor-producing capacity assays were conducted on the key odor-producing algal strain *Pseudanabaena* sp., screened from a water source. Under varying nitrogen concentrations and with a 13-day growth cycle, the effects on extracellular and intracellular MIB were investigated using indicators including dry weight, cell count and chlorophyll content. The results showed that *Pseudanabaena* sp. exhibited faster growth rates and stronger odor-producing capacity under high nitrogen concentrations, with the maximum odor compound (2-MIB) reaching 161 μg/L.
