This study aimed at applying different intensities (30 and 60mT) and exposure times (24 and 1hd) of MF to cultures of Chlorella kessleri and evaluated their effects on cell growth, proximate composition of biomass, pigment production and antioxidant activity. The condition of 60mT for 1hd stimulated biomass concentration of 83.2% by comparison with control culture (CC). Besides stimulated 13.7% lipid synthesis, 38.9% chlorophyll a and 59.1% chlorophyll b, 25.0% total carotenoids and antioxidants up to 185.7%. Thus MF application is an excellent alternative to stimulate cell growth and high biotechnological interest biocompounds.
本研究旨在应用不同强度（30 和 60mT）和暴露时间（24 和 1 小时）的 MF 对小球藻培养物进行处理，并评估其对细胞生长、生物质的近似成分、色素产生和抗氧化活性的影响。与对照培养物（CC）相比，60mT 条件下 1 小时刺激了 83.2%的生物质浓度。此外，MF 处理还刺激了 13.7%的脂质合成、38.9%的叶绿素 a 和 59.1%的叶绿素 b、25.0%的总类胡萝卜素和 185.7%的抗氧化剂。因此，MF 的应用是刺激细胞生长和高生物技术应用生物化合物的极好选择。
