Abstrakt: Photoacoustic spectra of cells ofM.roseuswere recorded to study thein vivocharacteristics and localisation of the carotenoid pigments in these cells. The PA spectra indicated that both the psychrotrophic and mesophilic strains had similar chromophores. Theciscarotenoids were prominent in the psychrotrophicM.roseuswhereas shorter polyenes were more prominent in mesophilicM.roseus.Further, depth profiling photoacoustic studies revealed that in both the strains ofM.roseusthe bulk of the chromophore was associated with the cell membrane.
