Abstract
The physical and chemical properties of the carotenoid pigments of Micrococcus lysodeikticus have been determined. Following saponification, at least seven different pigments can be separated by column-chromatographic procedures. These pigments have similar absorption spectra but differ in polarity. The absorption spectra of these bacterial pigments are similar to those of the carotenoid neurosporene. Polar pigments predominate and no hydrocarbon carotenoids have been detected.
Absorption maxima, partition coefficients, reaction to I2 and acids and melting points were determined.
The nature of the polar groupings present in these pigments and their relation to other bacterial pigments are discussed.
