Abstract

Experimental results demonstrating the cultivation of photosynthetic microorganisms using laser light were presented. The well-studied anoxygenic photosynthetic bacterium, Rhodobacter capsulatus, was used as the model organism. A vertical-cavity surface-emitting laser (VCSEL) was chosen as a light source uniquely suitable for the cultivation of this photosynthetic microorganism based on the complementarity of the bacterial absorbance spectrum and the wavelength of the laser-emitted light.
