Effect of Visible Rays on Bacterial Growth

Abstract

I NOTE with great interest that experimental work is being done to investigate the effect of visible rays on bacterial growth. During a course of lectures I gave at the Royal Institution in 1911, I showed specimens of B. prodigiosus which I had subcultivated for several generations in a narrow band of spectral light having a maximum at 620 m, which exhibited very marked red pigment formation, and similar cultures grown in light of 550 m and 450 m, which were respectively yellow and whito. I also gave details of the accelerated production of wood alcohol and other fermentation products by irradiating the culture flasks with rays of selected wave-length in the visible spectrum.
