Multimode microalgae culture equipment

Abstract

The invention belongs to the field of microalgae culture, and discloses multimode microalgae culture equipment. The multimode microalgae culture equipment comprises an outer box assembly and a plurality of culture units, wherein the outer box assembly comprises an outer box, an air pump, fluorescent tubes and a plurality of sample bottles, and the culture units are in one-to-one correspondence tothe sample bottles; each culture unit comprises culture tanks and pressure densimeters; the air pump is used for pumping air into the outer box from outside; the fluorescent tubes are arranged in theouter box; the sample bottles are arranged outside the outer box; each culture tank is provided with a microalgae injection port and a culture medium injection port; and each pressure densimeter is provided with two pressure detection pieces located at different heights, and is used for detecting the real-time density of a microalgae solution through the real-time pressure difference detected by the two pressure detection pieces. Therefore, culture of the microalgae in three manners by the equipment can be completed, and data acquisition is performed, and subsequent sample contrast and analysis are performed.

Description

technical field [0001] The invention belongs to the field of microalgae cultivation, and in particular relates to multi-mode microalgae cultivation equipment. Background technique [0002] Microalgae are microscopic, unicellular or multicellular organisms that contain chloroplasts and are able to perform photosynthesis and fix carbon dioxide from the air. Compared with traditional plants, it has the advantages of high photosynthetic utilization rate and fast growth rate. In recent years, microalgae have been widely used in aquaculture, nutrition and health care, cosmetics, environmental purification, bioenergy and other fields. [0003] Microalgae can be cultured in three ways: autotrophic, heterotrophic, and combined. Autotrophy refers to the cultivation method in which sufficient light is provided to microalgae, and microalgae use light energy through photosynthesis of chloroplasts to fix carbon dioxide for growth. Carbon dioxide in the air is the main carbon source. He...

AI Technical Summary

Problems solved by technology

[0004] The microalgae cultivation equipments in the prior art are all designed for specific microalgae cultivation methods, but obviously there are still the following deficiencies in these equipments: 1. None of the equipment can realize three kinds of microalgae cultivation in autotrophy, heterotrophy and concurrent culture. For the cultivation of microalgae under the cultivation method, if it is necessary to conduct comparative analysis of three different cultivation methods, there are often a variety of different microalgae cultivation equipment. 2. These microalgae cultivation equipment cannot achieve good air tightness. , installation and other processes are prone to contamination, which will affect the research results. 3. The current culture equipment is single group and single tank, and it is impossible to complete the control experiment of multiple groups of samples alone

4. The heterotrophic culture in the prior art is carried out under the condition of completely avoiding light, and the culture equipment is completely covered. During the culture stage, it is difficult to understand the internal growth of microalgae
