绿藻克雷伯氏菌属(Klebsormidiales, Streptophyta)的成员是全世界生物土壤结皮群落的典型组成部分，发挥着重要的生态功能。 Klebsormidium Fluitans (F. Gay) Lokhorst 是从航空陆地生物膜以及蒂罗尔和南蒂罗尔阿尔卑斯山（奥地利、意大利）沿 600 至 2350 m 海拔梯度的四种不同生物土壤结皮中分离出来的，其特点是季节性高太阳辐射。由于克雷伯索啶的紫外线耐受性尚未得到详细研究，因此应用了生态生理学和生化研究。受控人工紫外线辐射（UVR；< 9 W m(-2) UV-A、
Members of the green algal genus Klebsormidium (Klebsormidiales, Streptophyta) are typical components of biological soil crust communities worldwide, which exert important ecological functions. Klebsormidium fluitans (F. Gay) Lokhorst was isolated from an aeroterrestrial biofilm as well as from four different biological soil crusts along an elevational gradient between 600 and 2350 m in the Tyrolean and South Tyrolean Alps (Austria, Italy), which are characterised by seasonally high solar radiation. Since the UV tolerance of Klebsormidium has not been studied in detail, an ecophysiological and biochemical study was applied. The effects of controlled artificial ultraviolet radiation (UVR; < 9 W m(-2) UV-A,
