Preliminary data for comparing antibiotic hormesis against nitrogen starvation in Scenedesmus sp.

The present dataset is a preliminary investigation on the hormetic effects of antibiotic supplementation on Scenedesmus sp. growth, chlorophyll, fatty acid methyl ester (FAME) profile, and metabolite productivities (alpha-linolenic acid, alpha-tocopherol). It compares the results obtained with those of nitrogen limitation and sequential nitrogen starvation. The analysis showed that antibiotic supplementation triggered monounsaturated fatty acid (MUFA) accumulation and significant increase in alpha-linolenic acid and alpha-tocopherol productivities compared to both nitrogen limitation and sequential nitrogen starvation. The dataset could be useful for algal biotechnology with possible applications in targeted algal farming for high-value metabolites.

本数据集对抗生素补充剂对栅藻（Scenedesmus sp.）生长、叶绿素、脂肪酸甲酯（FAME）谱和代谢产物产量（α-亚麻酸、α-生育酚）的类回声效应进行了初步研究。它将所得结果与氮限制和连续氮饥饿的结果进行了比较。分析表明，与氮限制和连续氮饥饿相比，抗生素补充剂触发了单不饱和脂肪酸（MUFA）的积累以及α-亚麻酸和α-生育酚产量的显著增加。该数据集对于藻类生物技术可能具有实用性，并在针对高价值代谢物的藻类养殖中具有潜在应用。
