Zusammenfassung:CAROTENOIDS have been noted as constituents of a number of bacteria 1 , possibly associated with protein compounds 2 . In a chemical analysis of the protoplast membrane of Micrococcus lysodeikticus 3 , the absorption spectrum of a solution of the lipid fraction in petroleum ether, obtained by solvent extraction of the membrane, indicated the presence of lutein. However, the carotenoid was unstable in organic solvents and consequently the quantitative estimation gave a value believed to be low. It has now been found possible to determine the pigment in the membrane without preliminary extraction.
