Epipsammic diatoms have important implications for ecosystem processes in lotic environments. Most of the studies on benthic diatoms concentrate on epilithic diatoms and very little is known about epipsammic diatoms. The objective of this study was to assess epipsammic diatom communities in streams in relation to environmental conditions. Epipsammic diatoms and water quality sampling was done a...

Benthic diatoms and bacteria often co-operatively build up phototrophic epilithic biofilms. Studying the properties and contributions of the individual partners requires the establishment and maintenance of axenic cultures of the involved organisms. Axenification of biofilm organisms is often challenging, because bacteria as well as diatom cells are embedded in a matrix of extracellular polymer...

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...
