Název v původním jazyce

Microbial colonization of halite from the hyper-arid Atacama Desert studied by Raman spectroscopy

Popis výsledku v původním jazyce

Microbial life is very rare in soils of Atacama hyper-arid region, and autotrophic microorganisms are virtually absent. These endoevaporitic colonies are an example of life that has adapted to the extreme dryness by colonizing the interior of rocks thatprovide enhanced moisture conditions. Here, we present non-destructive Raman spectroscopical identification of these colonies and their organic remnants. Spectral signatures revealed the presence of UV-protective biomolecules as well as light-harvestingpigments pointing to photosynthetic activity. Compounds of biogenic origin identified within these rocks differed depending on the origins of specimens from particular areas in the desert, with differing environmental conditions.
