THE TOTAL LUMINOUS EFFICIENCY OF LUMINOUS BACTERIA [PDF]

open access: yesJournal of General Physiology, 1925
Methods are described for measuring the light emitted by an emulsion of luminous bacteria of given thickness, and calculating the light emitted by a single bacterium, measuring 1.1 x 2.2 micra, provided there is no absorption of light in the emulsion. At the same time, the oxygen consumed by a single bacterium was measured by recording ...
