| Research Abstract |
Some of microalgae can proceed photosynthesis even on a solid surface. I constructed a belt conveyor system with which microalgae on the belt fix CO_2 from atmosphere. Chlorella, Chlamydomonas, Porphyridium, Spirulina, and Synechocystis were still active even on a membrane of glass-fiber filter. Though the system worked semi-automatically, the algal cells dried soon outdoors due to dried wind. Thus I am still looking for an appropriate transparent film which would be laid over the algae on the belt. The film should be better if molecules of CO_2 and O_2 can be transferable, but not H_2O.Infrared gas analysing system with which rate of photosynthesis is determined at real time was applied to the microalgae on the membrane. It took over 15 min in Spirulina till the rate of photosynthesis reached the stationary level after illumination, while it was very soon in Chlorella. It is also found that acid lipids in thylakoid membranes play a role of maintenance of photosystem II protein complex.
