Objective:To study the effect of12.5 mT and 120 mT static magnetic field on the growth of Bacillus acidophilus. Methods: Bacillus acidophilus were separately cultured in normal condition
12.5 mT and 120 mT static magnetic field for 24 hours.After 8 hours
the bacterial growth amount was assayed by means of the OD value and cloney forming unit (CFU)method. Results:the OD value and the live bacterium number of the 12.5 mT group had no significant difference with the control group (P>0.05)
while the value of the 120 mT group was lower than the control (P<0.05). Conclusion:The study indicates that 12.5 mT static magnetic field has no effect on the growth of Bacillus acidophilus
while the 120 mT static magnetic field can inhibit the growth of the bacterium
while further study is needed to reveal the effect of static magnetic field on the growth of other oral microorganism.
