It was observed that magnetic fields of various strenghts between 60-580 gauss influenced the growth rate of Chlorella. When the incubation was carried out in a liquid medium containing 0.5% glycine as carbon source (pH 6.0) under light irradiation of 4,100 lx at 25℃, the magnetic field was found to make the growth rate of Chlorella lower; the specific growth rate, μ, was 2.83-2.86 day^<-1> without the magnetic field and 2.56-2.60 day^<-1> with a magnetic field of 580 gauss. No magnetic field effect was observed without light irradiation. The value of μ was lowered from 2.00-2.06 to 1.79-1.85 day^<-1> in the magnetic field of 580 gauss in a liquid medium containin (NH_4)_2SO_4 in place of glycine used with passing air, which contains 0.03% CO_2. On the other hand, little effect of a magnetic field was observed on the growth rate with passing a mixture of CO_2 and air.
