Photo-bioreactor

The utility model relates to a microalga field of breeding especially relates to a photobioreactor. The tympanic bulla phenomenon among the culture solution transportation process can be reduced, the immobilization cultured output of microalga is improved. Overcome among the prior art among the culture solution transportation process, the unable emission of bubble be in easily between base plate and the infusion layer, between infusion layer and the carrier and the tympanic bulla phenomenon takes place between said carrier and the microalga cellular layer, leads to the lower drawback of immobilization cultured output of microalga. The embodiment of the utility model provides a photobioreactor, include: the reactor main part, said reactor main part contains base plate and carrier, and set up in infusion layer between base plate and the carrier, said base plate with on the contact surface on infusion layer is provided with exhaust portion, exhaust portion and air exhaust device feed through mutually.
