In Malaysia, if the goverment or the panels approved our proposal on algae research, i think it already go to International Space Station ISS. Unfortunately we have to struggle for last 5 years. Probably with the help of light energy, we can produce biomass, emit oxygen, and consume CO2. Microgravity, i.e. reduced gravity, will influence the orientation of the cells and aggravate mass transfer and heat exchange. This will contribute to green house effect and climate change or global warming. Malaysian panels need to be educated.... BUT by that time I retired.

After first experiments on earth, the scientists will test the microalga-based photobioreactor system during parabolic flights with the airbus ZERO-G. They will study the influence of microgravitation on photosynthetic activity, the respiration of the algae as well as on potential hydrogen production. After the algae will have survived the parabolic flights, tests on satellites or the International Space Station ISS will follow. http://www.kit.edu/visit/pi_2012_10082.php
