Using Raman spectroscopy to detect scytonemin of epiliths and endoliths from marble, serpentinite and gypsum

Here, we present Raman spectra showing the presence and distribution of scytonemin carotenoids in epilithic endolithic colonisations from temperate locations Central Europe Sicily. In Bohemian Massif, marble serpentinitic cyanobacterial epiliths dominated by cyanobacteria Scytonema, Stigonema, Hassallia, Gloeocapsopsis Gloeocapsa were investigated using light microscopy spectroscopy. Scytonemin was a common dark pigment, accompanied gloeocapsin on marbles Opolenec serpentinites Holubov (South Bohemia). other sites originated gypsum. They located Carpathian foredeep (Badenian, Silesian unit, eastern Poland) Messinian complexes Mediterranean area (Sicily). Similarly to previous localities, almost ubiquitous occurrence confirmed colonisations. Obtained findings are important spectroscopic point view. Additionally, comparing results several both endoliths areas that cannot be considered climatically extreme, although they experience rapid fluctuations temperature, humidity UV irradiation exposed rocky substrates.
