Beschreibung
Zusammenfassung:	This invention discloses a mutated strain of wild type Bacillus mucilaginosus HSCUP-76-8 and a high-density fermentation method thereof. The mutated strain HSCUP-76-8 was assigned an Accession No. CGMCC No. 8481. A two-stage and regulated high-density fermentation method has been established for the production of HSCUP-76-8. In the first stage, parameters are controlled to reduce the viscosity of the fermentation broth and promote the growth of bacteria, thereby allowing the bacteria to reach an amount in the range of 2.0×109 cfu/mL-2.3×109 cfu/ml. In the second stage, nutritional factors and fermentation conditions are controlled to promote sporulation, thereby producing endospores in the range of 1.5×109 cfu/mL-2.0×109 cfu/ml. The fermentation cycle of the two-stage high-density fermentation is 32-48 hours.
