Abstract:

Studied in this paper are some changes of lethal rate,pigment content,protein content,total lipid content and scavenging activity on radicals of Chlamydomonas nivalis exposed to UV-B with diferent dosages.The resuits show that UV-B radiation is lethal for Chlamydomonas nivalis,and that the contents of chlorophyll,carotenoid and astaxanthin increase after the radiation.Moreover,the basic biochemical components of Chlamydomonas nivalu
obviously change after the UV-B radiation,that is,the protein content decreases,the total lipid content increases,and the scavenging activity on radicals of Chlamydomonas nivalis in organic solvent improves.

Key words: Chlamydomonas nivalis, UV—B radiation, biological effect, pigment content
