MAGNETOBIOLOGICAL EFFECTS ON A CYANOBACTERIUM, ANABAENA-DOLIOLUM

Exposure time and magnetic-pole-dependent physiological response of a cyanobacterium, Anabaena doliolum, were studied by exposing the sample s to two poles [north (N) and south (S)] of a 0.3 Tesla permanent magn et for 1-6 h. Study revealed that both magnetic poles, N and S, produc e different effects, depending on the length of exposure. However, phy siological response of the cyanobacterium to N + S mixtures was signif icantly different from the response to either of the poles, N or S, su ggesting a change in structural chemistry of the water or nutrient sol ution responsible for the magnetobiological effects.
