The invention discloses a fermentation method which uses Phaffia rhodozyma to coproduce astaxanthin and Fructooligosaccharide, comprising the following main technical flows: culturing strains, carrying out high-yield fermentation on astaxanthin, replenishing high-concentration cane sugar and glucose syrup, and controlling the condition to covert and produce Fructooligosaccharide. The invention is mainly characterized in that when astaxanthin fermentation almost ends, the mixture of high-concentration cane sugar and glucose syrup is replenished, and the Fructooligosaccharide is obtained by conversion. The method utilizes Phaffia rhodozyma cultured in one batch to simultaneously produce astaxanthin and Fructooligosaccharide at high yield, thus greatly lowering the cost for culturing Phaffia rhodozyma and producing astaxanthin.

The invention provides a 3D printing microfluidic device and a method for preparing a monodisperse emulsion with large throughput. 3D printing is used to make microfluidic devices. The device is in the shape of a cylinder with a cylindrical channel in the center. The liquid buffer channel is connected to multiple radially distributed microchannels. The microchannels are connected to the external collection tank through the slit area. The slit The area is flat and wedge-shaped. When the dispersed phase is injected from the liquid inlet, enters the liquid buffer channel, flows into the radially distributed microchannels from the liquid buffer channel, and when the fluid enters the flat slit area through the microchannel, under the extrusion of the side of the slit, it has a relatively Large Laplace pressure, the wedge-shaped structure will cause the droplet to be subjected to a Laplace pressure difference between the inside and outside, the pressure difference pushes the droplet to flow in the wedge-shaped structure, and finally squeezes the droplet from the wedge-shaped structure to the collection tank middle. The size of the generated droplets can be controlled by changing the structural parameters of the channel, and the size of the prepared droplets is uniform, so that a large number of monodisperse emulsions with uniform and controllable sizes can be prepared. The method has the advantages of simple manufacture and low cost, and can realize industrialized production.
