Half-dry solid-state adherent culture device for microalgae industrial production

Abstract

The invention belongs to the field of microalgae culture, and in particular relates to a half-dry solid-state adherent culture device for microalgae industrial production. The half-dry solid-state adherent culture device comprises a bracket system, adherent culture units, a supporting shaft transmission system, a speed regulating motor, liquid supplementation pipes, collection grooves and a culture medium liquid storage tank, wherein at least one adherent culture unit is arranged on the bracket system and is connected with the speed regulating motor through the supporting shaft transmission system; the liquid supplementation pipes are respectively arranged above the adherent culture unit and are communicated with the culture medium liquid storage tank through pipelines; the collection grooves are respectively formed below the adherent culture unit and are communicated with the culture medium liquid storage tank through liquid collection pipes; a liquid circulating pump and a carbon supplementation device are arranged in the culture medium liquid storage tank. The half-dry solid-state adherent culture device can be used for producing microalgae biomass and secondary metabolites on a large scale; the yield in unit floor area is effectively improved; the culture period is shortened; the culture water consumption is greatly reduced; the cost of the culture device and the operation cost are reduced; the industrial magnification is facilitated.

Description

technical field [0001] The invention belongs to the field of microalgae cultivation, in particular to a semi-dry solid-state adherent culture device for industrial production of microalgae. Background technique [0002] Microalgae refers to aquatic planktonic algae capable of photosynthesis. Some microalgae are rich in protein and can be used as aquatic bait or livestock feed (such as spirulina); more importantly, some microalgae can synthesize a large amount of secondary metabolites, such as oil, carotenoids, polysaccharides, etc. , These substances are often biologically active substances with extremely high economic value, and can be used in functional foods, food additives, pharmaceuticals, bioenergy and other fields. In particular, extracting microalgae oil through large-scale cultivation of microalgae, and then transforming it into biodiesel is considered to be one of the most important ways to solve the problem of bioenergy production and carbon sequestration and emi...
