“…Different stress conditions are known to cause an enhanced production of ROS, for example, high light intensity (Choo et al, 2004), carbon depletion (Choo et al, 2004), pollutant metal (Okamoto and Colepicolo, 1998), and microgravity (Li et al, 2004). Increasing the level of ROS can lead to severe cellular injury or death.…”

Photosystem efficiency and the characteristic on oxidative stress were examined to elucidate the metabolic responses of Synechocystis sp. PCC 6803 to short-term clinorotation. Results compiled when using clinostat to simulate microgravity for 60 h, showed that clinorotation clearly prohibited the photochemical quantum yield, but promoted the synthesis of chlorophyll and total protein. This may be a compensatory mechanism for the algal cell to maintain its normal metabolism. An increased malondialdehyde (MDA) content of algal cell upon clinorotation, together with an enhanced catalase (CAT) activity was observed during the whole period of clinorotation. One conclusion is that short-term clinorotation acts as a kind of stress, and that these physiological responses may be a special way for an algal cell to adapt itself to a different environment other than earth gravity.
