Effect of different protocols for applying a magnetic field (0.03T) on growth, viability and pigment composition of Haematococcus pluvialis Flotow in sufficiency and absence of nitrogen
Journal Title: Biotecnología Vegetal - Year 2009, Vol 9, Issue 2
Abstract
The effect of a magnetic field (0.03T) on growth, cellular viability and pigments accumulation in Haematococcus pluvialis was studied in order to validate potentialities for market. Magnetic field favored growth and cellular division when applied in the exponential phase of growth, with a direct incidence on chlorophylls synthesis. Culture exposition to magnetic field; during 15 min or in a permanent way, favored to obtain maximum cellular densities and an appropriate cellular viability. Culture time was reduced as an advantage for commercial scaling processes. Magnetic field stimulated cellular growth of cultures in N-starvation conditions, offering evidences of a growth and viability modulation induced by stress.
