Hollow microculture film plate and microculture system

Abstract

The invention discloses a hollow microculture film plate. The hollow microculture film plate is limited along a plate thickness direction and a direction perpendicular to the plate thickness direction. The plate is composed of multiple film wires and comprises first and second outer surfaces opposite along a plate thickness direction. Each one of the film wires comprises a film wall. The film wall comprises liquid-permeable micropores and limits corresponding film wire inner pores. A liquid fed into the inner pores of the film wires goes through the micropores in the film walls of the corresponding film wires and then reaches the first and second outer surfaces. The microorganisms to be cultured adhere to and grow on the first and second outer surfaces.

Description

technical field [0001] The present application relates to a hollow microorganism culture membrane plate and a microorganism culture system comprising the hollow microorganism culture membrane plate. Background technique [0002] Photosynthetic microorganisms are a group of microorganisms that use light as the sole or main source of energy, including microalgae, cyanobacteria and other microorganisms that contain chlorophyll and can perform photosynthesis. Microorganisms have important biological utilization value. Especially microalgae (such as spirulina), which are rich in protein, can be used as aquatic bait or livestock and poultry feed; more importantly, some microalgae can synthesize a large amount of secondary metabolites under specific conditions, such as oil, carotenoids, polysaccharides , a variety of biologically active substances and trace elements, etc. These substances have high economic value and can be used in functional foods, food additives, pharmaceuticals ...

AI Technical Summary

Problems solved by technology

The characteristic of this method is that the whole cultivation process does not rely on water as a support system, and the fiber itself provides a certain culture medium for microalgae, which can reduce energy consumption, increase productivity, and improve space utilization to a certain extent, but within a certain height range , the amount of liquid released by the fiber itself for microalgae cultivation is uncontrollable within the vertical height. When the liquid consumption at the top is met, the liquid supply at the bottom is insufficient to meet the growth needs of microalgae; when the liquid consumption at the bottom is met, the liquid at the top Excessive amounts, causing microalgae on the outer surface to be washed away

Therefore, the control of liquid volume is a difficult point that cannot be broken through in the current semi-dry solid-state culture method.
