polyfructan produced by the levansucrase from Bacillus megaterium has a molecular mass of 2711 kDa and consisted mainly of beta(2,6) linkages. Besides the polyfructan formation, the wild-type levansucrase of Bacillus megaterium also synthesizes five different detectable oligosaccharides. Three products are identified: 1-kestose (isokestose), 6-kestose and nystose which are known acceptors for the transfer of fructosyl units

design and evaluation of a bi-enzymatic system: combined use of levansucrase from Bacillus amyloliquefaciens and endoinulinase from Aspergillus niger in a one-step reaction for the synthesis of fructooligosaccharides (FOS) and oligolevans using sucrose as the sole substrate, overview. At the initial stage of time course, short chain fructooligosaccharides, 1-kestose, nystose, and 1F-fructosylnystose are the major products, whilst 6-kestose, medium chain fructooligosaccharides (mcFOSs, levanohexaose, levanopentaose) and oligolevans become the dominant ones at the late stage.

Quantification of Lsc in supernatants and cellular protein samples of mutants defective in either lscB or lscC confirm that LscB secretion at low temperature is due to a combination of thermo-regulated transcription and secretion.
