In this study, the effect of various initial Zn concentration additionally on microalgae growth and biochemical composition were investigated. The Spirulina platensis biomass of each concentration reached the maximum at the end of the cultivation. However, high levels could severely inhibit the growth of microalgae. Fluorescence activity occurred changes in response to heavy metal stress. Moreover, biochemical composition in Spirulina platensis altered under zinc stress, and the highest contents of phycocyanin (PC), Chlorophyll-a (Chl-a), Carotenoid and zinc accumulation were obtained. The proportion of saturated and polyunsaturated fatty acids increased constantly in response to Zn exposure. Overall, this study indicated that the use of Spirulina platensis is a viable method for treating zinc containing wastewater and harvested microalgae can be processed into high-zinc products.
在这项研究中，研究了不同初始 Zn 浓度对微藻生长和生物化学组成的影响。每种浓度的螺旋藻生物量在培养结束时达到最大值。然而，高浓度会严重抑制微藻的生长。荧光活性因重金属胁迫而发生变化。此外，锌胁迫下螺旋藻的生物化学组成发生改变，获得了藻蓝蛋白（PC）、叶绿素-a（Chl-a）、类胡萝卜素和锌积累的最高含量。随着 Zn 暴露，饱和脂肪酸和多不饱和脂肪酸的比例不断增加。总的来说，这项研究表明，利用螺旋藻是处理含锌废水的一种可行方法，收获的微藻可以加工成高锌产品。
