Effects of UV-B radiations on non-marine Antarctic microalgae
Listed in NASA Earthdata CMR
This data set contains a list of 273 samples collected during the 1998-99 and 2000-2001 Italian Antarctic Expeditions in several non-marine environments of Victoria Land.
Description
In particular mosses, soils, benthic algal mats and snow samples were collected in order to study their microalgal content. Following the Ecophysiology and Ecotoxicology research line of the PNRA, microalgae were isolated on different culture media (BBM, BG11) from some samples in order to obtain monospecific massive cultures.
Those cultures were exposed to an UV-B lamp source at different times of exposition in order to determine changes in several molecules of photosynthetic apparatus and cell membranes after UV-B exposition. Using HPLC and spectrophotometer the algal content in Chlorophyll, carotenoids, N-tocopherol, phospholipids were determined before and after UV-B expositions.
