Functional Characterization of Recombinant Endo-Levanase (LevBk) from Bacillus koreensis HL12 on Short-Chain Levan-Type Fructooligosaccharides Production.

Levan-type fructooligosaccharides (L-FOSs) are a prominent class of non-digestible oligosaccharides with potential as nutritional prebiotics. Endo-levanase, which randomly hydrolyzes β-(2,6)-linkages in fructans, is a promising enzyme for short-chain FOS production. In this work, a recombinant levanase (LevBk) from Bacillus koreensis strain HL12 was characterized.
