Abstract
Levan is a microbial polyfructan which is constructed from the β-2, 6-fructofuranosyl main chain and, β-2, 1-fructofuranosyl-linked side chains. The enzymatic synthesis of levan has been well-studied for several decades. However, there was no detailed report describing the degradation of levan and levan degrading enzymes, and most of the previous reports were on unpurified enzymes. This paper deals with the screening of levan-degrading enzymes, enzymatic properties and classification of the newly obtained enzymes.
