Annotation

A spectroscopic study of the photosynthetic purple sulfur bacteria of the Chromatium genus is performed at various growth stages and under different culture conditions. Absorption and luminescence spectra of the bacterial cells are found to be useful in estimating their populations within certain concentration ranges. The relative proportion between the porphyrin and blue-band luminescence intensities can be used as an indicator of the physiological state of the culture.
