A kind of immobilized cultivation device and cultivation method

Abstract

The invention relates to the field of microalgae cultivation, in particular to an immobilized cultivation device and a cultivation method. The method can reduce the bubbling phenomenon during the conveying process of the culture solution, improve the supply stability of the culture solution, and further increase the immobilized cultivation output of microalgae. It overcomes the defects in the prior art that when the culture solution is transported, the air bubbles cannot be discharged so that bubbling occurs between the substrate and the infusion layer, resulting in poor supply of the culture solution and low yield of immobilized culture of microalgae. An embodiment of the present invention provides a fixed culture device, including: a base plate and a carrier, and an infusion layer arranged between the base plate and the carrier; wherein, the contact surface between the base plate and the infusion layer is provided with exhaust part, when the infusion layer supplies the culture solution to the carrier, the air bubbles in the culture solution are discharged to the outside of the immobilized culture device through the exhaust part.

Description

technical field [0001] The invention relates to the field of microalgae cultivation, in particular to an immobilized cultivation device and a cultivation method. Background technique [0002] Immobilized cultivation technology can be applied to large-scale cultivation of various microorganisms, and has become the only way to realize the large-scale proliferation of microalgae. The immobilized culture device usually consists of a substrate 1, an infusion layer 2 and a carrier 3, see figure 1 , and the substrate 1, the infusion layer 2 and the carrier 3 are connected to each other through the surface in turn, the substrate 1 is used for supporting, and the infusion layer 2 is used to provide culture fluid to the surface of the carrier, and the substrate attached to the surface of the carrier 3 The microalgae cell layer 4 is immobilized cultured. [0003] When cultivating by the above-mentioned immobilized cultivation device, due to the gas dissolved in the culture solution, ...

AI Technical Summary

Problems solved by technology

[0003] When cultivating by the above-mentioned immobilized cultivation device, due to the gas dissolved in the culture solution, when the culture solution is supplied, bulging will occur between the substrate 1 and the infusion layer 2, the infusion layer 2 and the carrier 3. Bubble phenomenon, so that the supply of culture solution is not smooth, the microalgae cell layer 4 attached to the carrier 3 is suspended in the culture solution supply layer, resulting in low yield of immobilized culture of microalgae
