Abstract

The invention relates to the field of immobilized cultivation, and particularly relates to an immobilized cultivation device, a harvesting device and an immobilized cultivation method. The nutrient solution is supplied evenly, cell detachment is reduced and the cultivation yield is increased. The defects of the prior art that the nutrient solution is supplied directly to flush the cultivation surface and easily cause the cell detachment and the nutrient solution is unevenly supplied through the nutrient solution supply mode can be overcome. The immobilized cultivation device comprises a storage device and a cultivation device, wherein the storage device is used for providing microalgae nutrient solution; the cultivation device comprises at least one hollow tubular body, the outer surface of the hollow tubular body is a microalgae immobilized cultivation surface, the hollow tubular body is communicated with the storage device, pores are formed in the hollow tubular body, and nutrient solution flowing through the interior of the hollow tubular body is penetrated through the immobilized cultivation surface through the pores.

Description

technical field [0001] The invention relates to the field of microalgae cultivation, in particular to an immobilized cultivation device, a harvesting device and an immobilized cultivation method. Background technique [0002] Immobilized culture technology is an emerging culture technology that can be applied to large-scale culture of various microorganisms. Immobilized culture refers to the process of immobilizing free cells or microorganisms on a certain carrier, making them highly dense and maintaining biological activity, and rapidly proliferating under suitable conditions. The concentration of microorganisms and the ability of microorganisms to resist unfavorable environments can be improved through immobilized cultivation, and solid-liquid separation is facilitated after cultivation is completed, which can shorten the harvesting time. [0003] At present, the fixation methods of immobilized culture mainly include adsorption method, embedding method, cross-linking meth...
