Microbial culture plate and microbial culture system

Abstract

The present application discloses a microbial culture plate having a top end for supplying liquid in a vertical direction and a bottom end for discharging liquid, and a plate connecting the top end and the bottom end in a transverse direction perpendicular to the vertical direction. A first side and a second side, and comprising a first film layer and a second film layer, further comprising opposite first and second outer surfaces respectively provided by said first film layer and second film layer, to be The cultured target microorganisms are immobilized on the first outer surface and the second outer surface, the first membrane layer and the second membrane layer have micropores suitable for liquid penetration, wherein the first membrane layer A layer and a second membrane layer are sealingly joined together at first and second sides to form a hollow interior space through which liquid supplied from the top end penetrates the first and second membrane layers A layer reaches the first outer surface and the second outer surface.

Description

technical field [0001] The present application relates to a microorganism culture plate and a microorganism culture system comprising the microorganism culture 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 and other fields. Especially th...

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.
