Light/temperature dual-gradient microalgae incubator

Abstract

The invention relates to a light / temperature dual-gradient microalgae incubator. The incubator comprises an incubator body (1), wherein an insulation layer (2) is arranged outside the incubator body, a refrigeration zone (3) and a heating zone (8) are respectively arranged at the left and right sides of the incubator body, a working zone (5) is arranged in the middle of the incubator body, a refrigerator and a temperature controller are arranged in the refrigeration zone, and a heating rod and the temperature controller are arranged in the heating zone; metal grids (6) are uniformly distributed in the working zone (5), and a heat conduction medium (9) is arranged in the metal grids; a plurality of cold light lamps (7) are uniformly fixed and arranged in the same plane above the working zone (5) from less to more; and the arrangement direction of the cold light lamps is vertical to the directions of the refrigeration zone and the heating zone. The light / temperature dual-gradient microalgae incubator has simple structure; and by using a light and temperature dual-gradient control mode, selection of algal species and optimization of culture conditions can be carried out in an effective, rapid and high-flux manner, thus experimental microalgae light / temperature composite experiment data can be completed once, research and development period is shortened, research and development process is simplified, and an effective way is provided for research and development of algae.

Description

technical field [0001] The invention belongs to the field of biological cultivation, and relates to a biological cultivation device, in particular to a light / temperature double-gradient microalgae cultivation box capable of optimizing illumination and temperature cultivation conditions. Background technique [0002] Microalgae is a kind of unicellular or multicellular tiny plants growing in seawater or freshwater, which has important research and application value. The research and application of microalgae need to screen out the dominant algae species. Since the dominant algae species screened under different temperature and light conditions are different, the optimization of the light and temperature culture conditions of microalgae is the key to the development and utilization of algae resources. The necessary premise: Under different temperature and light conditions, different dominant algae species can be screened; different algae species have an optimal light and tempe...

Problems solved by technology

[0003] At present, the optimization of the light / temperature culture conditions of microalgae, that is, the selection of the optimum light and temperature conditions for microalgae, is obtained by conducting multiple rounds of experiments in temperature control instruments, and the time required for each round of experiments is one cycle of microalgae cultivation. cycle (quiescent culture takes about 20 days), so the optimization of light / temperature culture conditions for microalgae is an extremely tedious and time-consuming work. In addition, multiple rounds of experiments inevitably increase experimental errors and reduce the accuracy of experimental results. properties, thus affecting the optimization results of light / temperature culture conditions of microalgae

In terms of existing experimental equipment, manpower and time conditions, traditional methods can no longer meet the needs of microalgae biology experiments and microalgae research and development
