Abstract
The effect of static magnetic field (SMF) on Spirulina platensis growth and its influence on cadmium ions (Cd2+) removal efficiency were studied. Application of 6 h day−1 SMF resulted in the highest significant biomass productivity of 0.198 g L−1 day−1. However, 10 and 15 mg L−1 of Cd2+ resulted in significant reduction in biomass productivity by 8.8 and 12.5%, respectively, below the control. Combined SMF showed 30.1% significant increase in biomass productivity over the control. On the other hand, increase of initial Cd2+ concentration resulted in significant reduction of Cd2+ removal efficiency, representing 79.7% and 61.5% at 10 and 15 mg L−1, respectively, after 16 days. Interestingly, application of SMF for 6 h day−1 enhanced Cd2+ removal efficiency counted by 91.4% and 82.3% after 20 days for cultures with initial Cd2+ concentration of 10 and 15 mg L−1, representing increase by 6.3 and 25.3%, respectively, over the SMF-untreated cultures.
