Extremely low-frequency magnetic fields affect pigment production of Monascus purpureus in liquid-state fermentation


" The maximum yield of red and yellow pigment production had about 20 and 36 % increase for 8 days at 0.4 mT when treating fermentation broth compared to the control value. For sterile distilled water, a significant increase occurred at 0.4 mT compared to 0.1 mT for 5 h. However, the red and yellow pigment production decreased significantly at magnetic fields of 0.9 and 1.2 mT when treating fermentation broth and sterile distilled water. In contrast, the yield of both red and yellow pigment production decreased significantly compared with the control exposure for 3 and 5 h at a magnetic field of 0.4 mT."

Is interesting to note how variation in intensity inverts the outcome.
