Several studies have shown that any magnetic field (MF) applied to microalgae modifies its cultivation conditions and may favor biomolecule production since it interacts with the microorganisms and affect their growth. As a result, there are changes in concentrations and compositions of biomass and biomolecules. This review aims at updating MF applications to microalga cultures that were reported by studies conducted in the last 5 years. It shows the main studies that reached positive results of carbohydrate, lipid, protein and pigment production. Effects of MFs may be positive, negative or null, depending on some factors, such as intensity, exposure time, physiological state of cells and application devices. Therefore, this review details cultivation conditions used for reaching high concentration of biomolecules, explains the action of MFs on microalgae and describes their applicability to the biorefinery concept.
已有多项研究表明，任何施加于微藻的磁场都会改变其培养条件，并可能有利于生物分子的生产，因为磁场会与微生物相互作用并影响其生长。因此，生物质和生物分子的浓度和组成会发生变化。本综述旨在更新过去 5 年中报道的磁场应用于微藻培养的研究。它展示了主要的研究结果，这些研究都达到了提高碳水化合物、脂质、蛋白质和色素产量的积极效果。磁场的影响可能是积极的、消极的或中性的，这取决于一些因素，如强度、暴露时间、细胞的生理状态和应用设备。因此，本综述详细说明了达到高浓度生物分子的培养条件，解释了磁场对微藻的作用，并描述了它们在生物炼制概念中的适用性。
