| titleOfInvention | A kind of aspergillus niger seed continuous culture and method for producing citric acid |
| abstract | The invention discloses a method for continuous cultivation of Aspergillus niger seeds. The method includes the following steps: (1) in a start-up stage, inoculating Aspergillus niger spores into a seed medium to obtain seed liquid; (2) in a continuous seed cultivation stage, for The seed liquid obtained in step (1) is subjected to continuous dispersion treatment, and the seed liquid obtained by dispersion is continuously cultivated and supplemented with fresh seed feed medium; (3) in the stop stage, the replenishment of fresh seed feed medium and dispersion treatment is stopped, Continue to cultivate to obtain seed liquid, which is transferred into fermentation medium for fermentation culture. The method of the invention breakthroughly solves the problems of slow growth of multicellular filamentous bacteria and easy loss of mycelial balls in continuous culture, completely realizes the continuous culture of seeds, keeps the bacteria body constant in the optimum growth environment, and avoids bacterial growth. Seed degeneration, so that the seed liquid is in a continuous and stable state of high vitality, corresponding to the improvement of the performance of fermentation to produce citric acid. |
