✦ Synopsis

Economical light energy supply plays a Key role in determining the success of industrial application of photosynthetic microorganisms.

The bacteriochlorophyll a of C. thiosulfatophilum harvests the light at 760 nm, which oxidizes toxic HzS by photosynthesis. Light emitting diode(LED), which emits a maximum intensity at 710 nm and 60% of its maximum at 760 nm, was adopted as an alternative light source to inefficient incandescent light. With the array of the LEDs adjustable to the reactor wall 95% of -the light energy was saved over the incandescent light source in comparable conditlons~
