Embodiment 1

[0016] Such as figure 1 The shown airlift photobioreactor has a tank diameter of 182 mm and a riser diameter of 131 mm. The effective volume of the reactor is 2.5 liters. The gas distributor is a glass sand sintered perforated plate with a diameter of 30 mm and a pore size of 80 μ. The whole reactor is made of hard borosilicate glass. 4-8 20W daylight type energy-saving lamps are evenly distributed around the tank body. The single-cell marine cyanobacteria Synechococcus.sp.PCC.7002 was cultivated in the reactor, with Medium A as the medium, 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 2.36g / L.

Embodiment 2

[0018] The same effective volume as in Example 1 is an airlift photobioreactor of 2.5 liters. The single-cell marine cyanobacteria Synechococcus.sp.PCC.7002 mixed nutrient culture was carried out in the reactor, with Medium A as the medium, fed with 1% CO 2 At the same time as the air carbon dioxide mixture, add 3g / L glucose, 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 present invention relates to an integrated closed photobioreactor and its application, in particular to a laboratory-scale integrated airlift photobioreactor and its use for the suspension cultivation of algae and other photosynthetic biological cells . Background technique [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. There are horizontally placed serpentine pipe reactors, double-layer pipe reactors, and multi-branch parallel flow pipes. Type reactor, α-type pipeline reactor, spiral coiled pipeline reactor, etc. [0004] The b...
