A device to apply the MF during the cultivation was built and the cyanobacteria were exposed to a steady 11 mT transverse MF. The growth increased with MF application, and when it was applied for 1 h per day, 123% more biomass was produced than in the control group. The protein content in the biomass cultured under this condition increased, achieving 60.4 w/w, while the Chl-a increased by 326%. The MF application for 1 h per day was found to be more efficient than when applied continuously for 24 h per day, in addition to being more economical and sustainable. This study showed an inexpensive and non-toxic way to enhance biomass concentration, leading to amounts more than 100% higher than those obtained in the control group. Furthermore, the high protein content in the biomass gave us several possibilities to increase the nutritional value of food. %G English %2 https://uca.hal.science/hal-03583823/document %2 https://uca.hal.science/hal-03583823/file/Laroche%20Magnetic%20field%20action%20on%20limnospira%20...Deamici2022...%20Applied%20Sciences%20EDITEUR%20OA.pdf %L hal-03583823 %U https://uca.hal.science/hal-03583823 %~ PRES_CLERMONT %~ CNRS %~ UNIV-BPCLERMONT %~ INSTITUT_PASCAL %~ ACL-SPI %~ CLERMONT-AUVERGNE-INP %~ TEST3-HALCNRS
