Figure 5From: Raman and SEM analysis of a biocolonised hot spring travertine terrace in Svalbard, NorwayStackplots of 8 scytonemin spectra recorded at 785 nm. The arrow shows the carotene band at around 1515 cm-1, which is not related with the shift in scytonemin bands from 1172 cm-1to 1165 cm-1(marked by triangles), since no carotene is observed in the lower spectrum.Back to article page
