— The spectral distributions of two previously reported weak luminescences from liquid cultures of the yeast Saccharomyces cerevisiae have been determined. During the logarithmic phase of growth, emission was observed as a broad UV band between 200 and 425 nm, and as a visible region band between 525 and 700 nm. During the stationary phase, there were two narrow bands centred at 250 and 650 nm, and a broad band extending from 325 to 525 nm. The UV components are compared with Gurwitsch's mitogenetic radiation, and possible chemical and radiolytic sources of the luminescences are discussed.
