Bio-effect of Magnetic Field on Suspension-cultured Taxus chinensis var. mairei under Acid Stress
酸胁迫作用下悬浮培养红豆杉细胞的磁场生物学效应

The effect of direct current magnetic field (DCMF) on the cell growth and metabolism of suspension-cultured Taxus chinensis var. mairei under acid stress was examined. The experimental results showed that the ability of cell anti-acid stress, cell viability, biomass and intracellular protein were obviously enhanced by the DCMF. The viability of extracelluar PPO was enhanced, and accumulation of phenolics was restrained. Under certain HCl concentration, the higher the concentration of HCl, the stronger the bio-effect of the magnetic field. The obvious change of the medium pH and conductivity indicated that the ability of cell anti-acid stress was enhanced due to accelerated material transmembrane transportation by DCMF.
