| titleOfInvention | Aspergillus niger seed culture and citric acid preparation method |
| abstract | The invention discloses a method for culturing Aspergillus niger seeds and preparing citric acid by the Aspergillus niger seeds, which comprises the following steps: (1) taking mature aspergillus niger moldy bran spores to obtain dispersed spore suspension; (2) culturing the dispersed spore suspension in the step (1) to obtain germinated spores; (3) dispersing the germinated spores again, and culturing in a seed tank to obtain a mature seed solution; (5) transferring the mature seed liquid to a fermentation tank for culture and fermentation to obtain the citric acid fermentation liquid. The invention solves the problem of aggregation in the spore germination process, improves the spore balling rate, increases the number of mycelium pellets, effectively controls the size uniformity of the mycelium pellets, improves the conversion efficiency of thalli, improves the fermentation conversion rate and shortens the fermentation period. |
