Abstract:

GSH system plays a role in the control of the redox balance state,anti-oxidation and protecting life from injury of ROS(reactive oxygen species). In present paper, the possible GSH system of Chlamydomonas sp. ICE-L has been investigated by evaluating GSH and GSH-related enzymatic responses at different temperatures using spectrophotometer methods. The results showed that the GSH system is correlated positively to low temperature, and other factors but GR are correlated negatively to high temperature. So GSH and GSH-related enzymes play an important role in the adaptation of Antarctic ice microalgae to low temperature.

Key words: Chlamydomonas sp., ICE-L, Glutathione, Glutathione peroxidase, Glutathione reductase, Glutathione S-transferase, Acclimation to low temperature
