Estimation of bacterioruberin by Raman spectroscopy during the growth of halophilic archaeon Haloarcula marismortui.
Halophilic archaea are interesting microorganisms that produce low biomass and metabolites, complicating their quantification. Raman spectroscopy (RS) is a powerful technique, which requires small samples, attractive for using in archaeal research. The objective of this work was the estimation of bacterioruberin content along with Haloarcula marismortui growth and their correlation with biomass concentration. RS was used to detect characteristic bands of bacterioruberin (vibrational modes C═CH, C─C, and C═C) in H. marismortui culture samples. The intensity of Raman spectra in bacterioruberin and the biomass concentration were adequately correlated. The highest production of bacterioruberin occurred at 60 h. RS is revealed as a reliable technique for the estimation of bacterioruberin in the biomass of H. marismortui, which could be considered as a promising qualitative and quantitative technique to assay metabolites in cell cultures.
