Embodiment 1

[0029] The tank body 1 has a diameter of 182 mm, the riser 2 has a diameter of 131 mm, and the effective volume of the entire reactor is 2.5 liters. The gas distributor 6 is a glass sand sintered perforated plate with a diameter of 30 mm and a pore diameter of 80 μ. The whole reactor is made of hard borosilicate glass. Four to eight 20W energy-saving fluorescent lamps are evenly distributed around the tank to provide light. The single-celled marine cyanobacterium Synechococcus.sp.PCC.7002 is cultivated in the reactor, and Medium A is used as the medium, and 1% CO is introduced from the air pipe 3 2 Air carbon dioxide mixed gas, the gas volume is 400ml / min, and the inoculation density is 0.13g / L dry weight. After culturing for 5 days, the final density of algae cells reached 2.36g / L.

Embodiment 2

[0031] An airlift photobioreactor with an effective volume of 2.5 liters as in Example 1. The mixed nutrient culture of single-celled marine cyanobacteria Synechococcus.sp.PCC.7002 is carried out in this reactor. Medium A is used as the medium, 3g / L of glucose is added, and 1% CO 2 Air carbon dioxide mixed gas, the gas volume is 400ml / min, and the inoculation density is 0.13g / L dry weight. After culturing for 5 days, the final density of algae cells reached 3.6g / L.

Abstract

An integrated airlift-type photobiological reactor for culturing photosynthetic cells and rearching the relative metabolic products is composed of main body, cylindrical left tube coaxial with main body, and air distributor centrally extended from top to bottom. Its advantages are large light irradiated area, good liquid mix, high gas-liquid mass-transfer intensity, simple structure, high output and low cost.

Description

technical field [0001] The invention relates to an integrated closed photobioreactor and its application, in particular to a laboratory-scale integrated airlift photobioreactor and its use for suspension culture of algae and other photosynthetic biological cells. technical background [0002] At present, closed photobioreactors are still in the stage of experimental research, with various types and forms, and there are no finalized commercial products. There are mainly two types of closed photobioreactors in the experimental research stage: pipeline type and crate type. [0003] Pipeline photobioreactors are generally formed by bending transparent hard materials with small diameters into different shapes and connecting them. Reactor, α-type pipe reactor, spiral coil pipe reactor, etc. [0004] Box-type photobioreactors mainly include: horizontal plate photobioreactors, vertical slotted plate photobioreactors, multi-layer parallel plate photobioreactors, inclined bubbling p...
