Zusammenfassung:The invention discloses bacillus tequilensis Be14-2 CGMCC No. 7647 (China General Microbiological Culture Collection Center Number 7647), and an application of the bacillus tequilensis in polysaccharide metabolism. The bacillus tequilensis is inoculated in a czapek medium for inoculated cultivation, so that Pb tolerance is 2000mg/L, maximum Zn tolerance is 800mg/L, maximum Co tolerance is 400mg/L, and maximum Cu tolerance and maximum Hg tolerance are 100mg/L; a fermented culture can directly serve as an antioxidant; a concentration of polysaccharide with 50% hydroxyl radical (*OH) removed is 13.47mg/ml; the fermented culture can also be used for flocculating; and an activity range of the flocculating is 75.32-84.73%. The bacillus tequilensis is widely applied to the field of the polysaccharide metabolism, provides a new approach for industrially producing the natural polysaccharide, and has an important effect.
