Sterile air breather suitable for alga culture

Abstract

The invention relates to a sterile air breather suitable for alga culture. The sterile air breather comprises an air pump, a flowmeter and a filter, wherein the flowmeter and the filter are connected in series on a gas pipeline, a main gas pipe passing by the filter is communicated with a gas transmission framed bent, a plurality of gas outlet mouths are installed on each vertical gas guide pipe on the gas transmission framed bent, a gas outlet rubber pipe is inserted and connected in a lower port of each gas outlet mouth, a pipe clamp used for controlling on / off of each gas outlet rubber pipe is installed on the gas outlet rubber pipe, a lower port of each gas outlet rubber pipe is in inserted connection with a gas-filling through pipe inserted and installed in a rubber stopper in an opening of a triangular flask, each gas-filling through pipe extends into the corresponding triangular flask after passing through the rubber stopper in the opening of the corresponding triangular flask, an in-flask gas-filling rubber pipe extending to the bottom part of each triangular flask is inserted and connected in a lower port of the corresponding gas-filling through pipe, and meanwhile, an exhaust pipe communicated with the interior and the exterior of each triangular flask is inserted and installed in the corresponding rubber stopper. The sterile culture of the marine microalgae is implemented, the flow of the transmitted gas is controllable, one set of equipment provides multiple groups of culturing at the same time, and the structure of the device also lays a foundation for the large-area industrial aquaculture in future.

Description

technical field [0001] The invention belongs to the technical field of algae cultivation equipment, in particular to an aseptic ventilation device for algae cultivation. Background technique [0002] Marine microalgae are very rich in nutrients. In addition to rich in protein, amino acids, pigments, etc., they are also rich in high-value nutrients and chemical raw materials such as EPA and DHA. At present, marine microalgae are widely used in the pharmaceutical industry, food industry and animal feed. [0003] The cultivation of marine microalgae in the laboratory is carried out in triangular flasks, but this cultivation mode has certain limitations, and the gas can only enter through the sealing film, which cannot reach the CO2 required by microalgae. 2 However, using an air pump to inject gas cannot achieve gas sterility, and then cause microalgae to infect bacteria; therefore, it is of great significance to develop an effective aseptic ventilation device for algae cultiv...
