[Fermentative synthesis and hydrolysis of fructans].

The review of the experimental papers dealing with some aspects of fermentative biosynthesis of fructans with different degrees of polymerization from microorganisms and plants is presented. The role of sucrose 1F-fructosyltransferase and 1,2-beta-fructan 1F-fructosyltransferase in the biosynthesis and hydrolysis of fructans, the influence of different stresses (water, temperature, oxygen and others) on these process are discussed.
