Effects of UV-B radiations on non-marine Antarctic microalgae

Entry ID: uv_microalgae

[ Update this Record ]

Summary

Abstract: 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. 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 ...

SPECTROPHOTOMETERS

Quality A collection of benthic algal mats, mosses, soils, snow from several Victoria
Land localities with GPS. Isolation of microalgae from those samples through
the growing on selected culture media (BBM, BG11). Exposition of cultures to an
UV-B source in different times. Extraction of pigments and analysis (with
spectrophotometer and HPLC) to determine chlorophyll, carotenoids, fatty acids
content.
