Abstract
The invention discloses a method for producing L-sorbose through continuous fermentation, and relates to the technical field of biology and new medicine. The preparation method comprises the following steps: cross-linking aminated graphene, zinc oxide, sodium alginate and polyvinyl alcohol, and mixing with activated acetobacter aceti liquid to obtain immobilized acetobacter aceti; adding the immobilized acetobacter aceti and a fermentation culture solution into a fermentation tank, and carrying out continuous fermentation to produce L-sorbose; wherein the immobilization of the acetobacter improves the stability of thalli, prolongs the service time of the thalli, shortens the fermentation period, and is convenient to recycle after the fermentation is completed; a continuous fermentation process is adopted, and the purposes of saving energy, reducing consumption and improving quality and efficiency are achieved by simplifying the culture process of the seeds, reducing activation links and culture stages of the seeds and reducing manpower, material resources and energy consumption.
