DESULFURIZATION IN A PLATE-TYPE GAS-LIFT PHOTOBIOREACTOR USING LIGHT EMITTING DIODES
Hydrogen sulfide gas was removed in a 2-dimensional gas-lift reactor by the photosynthetic miicroorganism Chlorobium thiosulfatophilum using light emitting diodes (LEDs) as a light source. LEDs saved light energy by 99% compared with the incandescent light source. The plate-type gas-lift reactor removed hydrogen sulfide five times better per unit mg of protein, and performed two times better in the maximum performance per unit luminous flux, com- pared with cylindrical fermentors.
