Abstract

Magnetic fields (MF) may be generated, either by magnets or by electric current, and may interact with biological systems, causing changes in their properties. Thus, MF in microalga cultures may improve cell growth, alter biomass composition, and produce high-added-value biomolecules of interest. Therefore, this study is aimed at investigating the influence of low electromagnetic field (EMF) application (5 mT) on Chlorella fusca LEB 111 growth, biochemical composition of biomass, and carbohydrate productivity when cultivated in vertical tubular photobioreactors. EMF were applied for 1?h/day for 15?days. They stimulated C. fusca growth by 8.9?% and rendered 1.71?g/L biomass by comparison with the control culture (CC—without any EMF application). EMF application increased carbohydrate content (31.1?%) and carbohydrate productivity (3.54?mg/L·d), which were 24.7 and 35.8?% higher than the CC, respectively. Since studies of low EMF in microalga cultures are scarce, this study elucidated EMF application to C. fusca cultivation as a non-toxic and low-cost alternative whose focus is enhancement of carbohydrate production.

低电磁场对褐小球藻培养提高微藻碳水化合物产量的影响

磁场(MF)可以由磁铁或电流产生，并可能与生物系统相互作用，导致其性质的变化。因此，微藻培养物中的MF可以促进细胞生长，改变生物量组成，并产生高附加值的生物分子。因此，本研究旨在研究低电磁场(EMF) (5 mT)在垂直管状光生物反应器中培养对fusca小球藻LEB 111生长、生物量生化组成和碳水化合物产量的影响。电磁场应用于1?每天1小时，持续15天。他们刺激褐梭菌生长8.9?%，渲染1.71?g/L生物量与对照培养(cc -没有任何EMF应用)比较。EMF增加了碳水化合物含量(31.1%)和碳水化合物产量(3.54 mg/L·d)，分别为24.7%和35.8%。%，分别高于CC。由于低EMF在微藻培养中的研究很少，本研究阐明了EMF在fusca培养中的应用，作为一种无毒、低成本的替代方法，其重点是提高碳水化合物的产量。

期刊介绍： BioEnergy Research fills a void in the rapidly growing area of feedstock biology research related to biomass, biofuels, and bioenergy. The journal publishes a wide range of articles, including peer-reviewed scientific research, reviews, perspectives and commentary, industry news, and government policy updates. Its coverage brings together a uniquely broad combination of disciplines with a common focus on feedstock biology and science, related to biomass, biofeedstock, and bioenergy production.
