WITHDRAWN: Antioxidant properties and antimicrobial activities of Bacillus mojavensis I4 lipopeptides and application in the biocontrol of potato dry rots caused by Fusarium solani.

abstract：:Isomaltooligosaccharide (IMO) is a promising dietary component with prebiotic effect, and the long-chain IMOs are preferred to short chain ones owing to the longer persistence in the colon. To establish the optimal process for synthesis of long-chain IMOs, we systematically examined the reaction condition of dextransu...
