The present invention discloses a method for continuous production of stem cell exosomes and paracrine active macromolecules. Specifically, a hollow fiber membrane bioreactor is used to culture and enrich different products in stages, and culture fluid is harvested in stages, thereby improving the production efficiency of stem cell exosomes and paracrine active macromolecules. Meanwhile, an ultrafiltration+affinity adsorption series cycle is used to extract exosomes, so that the volume of the separation fluid can be rapidly reduced in the early stage of separation, and the concentration of exosomes is continuously increased, thereby making the adsorption of exosomes by affinity adsorption magnetic beads more and more efficient. The exosomes are adsorbed on the surface of the magnetic beads, effectively reducing the content of free exosomes in the separation fluid, effectively avoiding blockage of the ultrafiltration membrane and loss of exosomes, overcoming the shortcomings of the ultrafiltration method, namely, slower separation speed and product loss, and at the same time, overcoming the shortcomings of the affinity adsorption magnetic bead method, namely, the inability to process large-volume samples and high cost, which is conducive to promotion and application.

This invention discloses a method for alleviating cadmium stress on duckweed using ethyl caffeate. With industrial development, cadmium pollution in water bodies seriously threatens the ecosystem and human health, and traditional remediation methods have shortcomings. Although duckweed has the potential for water body remediation, cadmium stress inhibits its growth. This invention, through concentration gradient experiments, determines the maximum Cd concentration that duckweed can withstand. 2+ The optimal concentration of ethyl caffeate for alleviating cadmium stress is 200 μmol, with a concentration of 10 μmol. Adding 200 μmol of ethyl caffeate per 100 ml of cadmium-contaminated water significantly promotes duckweed growth, increases leaf number, fresh weight, and root length, enhances antioxidant enzyme content, reduces MDA content, increases chlorophyll content, and strengthens photosynthesis. It also significantly reduces cadmium accumulation in duckweed, achieving efficient bioremediation of cadmium pollution in water bodies. This method is simple to operate, low in cost, and environmentally friendly, showing broad application prospects in the field of water pollution control.
