Temperature controllable macro-algae suspension air inflation continuous culture device

Abstract

A temperature controllable macro-algae suspension air inflation continuous culture device comprises a conical flask, an air inflation device, a glass guide pipe, a rubber stopper, a cotton stopper, a temperature controllable heater, a water feeding valve and a drain valve. The air inflation device comprises air stones and an air inflation glass pipe. The water feeding valve is connected to the upper portion of the conical flask, and the drain valve is connected to the lower portion of the conical flask. The rubber stopper is installed at the opening of the conical flask. The air inflation device and the glass guide pipe penetrate through the rubber stopper and are arranged in the conical flask. The temperature controllable heater penetrates through the rubber stopper and is arranged in the conical bottle. The cotton stopper is arranged in the glass guide pipe. The temperature controllable macro-algae suspension air inflation continuous culture device has the advantages of being simple in structure and convenient to clean, the sterilization method is simple, the temperature period is convenient to adjust, the day and night temperature difference in the natural environment is simulated, a temperature gradient test is carried out, algae can be effectively prevented from being polluted by mould and hybrid algae, when a culture solution is replaced, the size of the culture solution in the device can be effectively guaranteed to be constant, and the continuous culture effect is achieved.

Description

technical field [0001] The invention relates to the technical field of large algae cultivation, in particular to a temperature-controllable suspension and aeration continuous cultivation device for large algae. Background technique [0002] There are many kinds of algal plants on the earth, and the output is huge. Algal plants and humans have direct and indirect relationships. It also plays an important role in economic development. Algae has important application value in the fields of industry, agriculture and medicine, so countries all over the world are investing a lot of manpower and resources in research on the development and utilization of algae. [0003] The research and utilization of algae must first carry out the separation and cultivation of algae. The algae are cultivated in the laboratory. Since the cultivation of algae is not carried out in a natural environment, the cultivation environment is too closed, and long-term algae cultivation will produce some ha...

Problems solved by technology

[0003] The research and utilization of algae must first carry out the separation and cultivation of algae. The algae are cultivated in the laboratory. Since the cultivation of algae is not carried out in a natural environment, the cultivation environment is too closed, and long-term algae cultivation will produce some harmful secondary substances. Metabolites, after long-term cultivation, these secondary metabolites will threaten the growth of algae and affect the cultivation of algae, thereby affecting the accuracy of subsequent experiments
