Growth stimulation and synthesis of lipids, pigments and antioxidants with magnetic fields in Chlorella kessleri cultivations

This study aimed at applying different intensities (30 and 60 mT) and exposure times (24 and 1 h d−1) 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 60 mT for 1 h d−1 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.
