Abstract
The present invention relates to the technical field of microbial reactors, and in particular to a method for using magnetic nanoparticles to target / destroy dead bacteria and release contents. The method of the present invention comprises the following steps: adding functionalized magnetic nanoparticles to a bioreactor containing dead bacteria and mixing them to obtain a mixed system; applying a magnetic field to the mixed system for treatment. The present invention places functionalized magnetic nanoparticles in a bioreactor containing dead bacteria and fully mixes them, and the functionalized magnetic nanoparticles have a greater probability of entering the dead cells through the pores in the dead bacterial cell walls; then a low-frequency magnetic field with a certain magnetic field strength and frequency is used to remotely control the nanoparticles entering the dead bacteria to move according to a specific trajectory and amplitude, and the functionalized nanoparticles entering the dead bacteria can use mechanical force from the inside to break the dead bacterial cell walls and release the contents, thereby increasing the substrate concentration of the bioreactor, reducing the amount of residue generated, and increasing the product yield.
