A novel beta -fructofuranosidase gene; a beta -fructofuranosidase encoded therewith; a method of isolating a beta -fructofuranosidase gene by using the novel beta -fructofuranosidase gene; a novel beta -fructofuranosidase obtained by the above method; a novel filamentous fungus which does not exhibit a beta -fructofuranosidase activity and is suited for producing beta -fructofuranosidases; a system for producing a recombinant beta -fructofuranosidase by using the above fungus as the host; and a beta -fructofuranosidase variant which forms specified fructo-oligosaccharides such as 1-ketoses from cane sugar selectively and efficiently. Nouveau gène de beta -fructofurannosidase; beta -fructofurannosidase codée par ce gène; procédé d'isolement d'un gène de beta -fructofurannosidase à l'aide de ce nouveau gène de beta -fructofurannosidase; nouvelle beta -fructofurannosidase obtenue selon ce procédé; nouveau champignon filamenteux ne présentant aucune activité de beta -fructofurannosidase et permettant la production de beta -fructofurannosidases; système pour la production d'une beta -fructofurannosidase recombinée, mettant en oeuvre ledit champignon à titre d'hôte; et variant de beta -fructofurannosidase formant sélectivement et efficacement certains fructo-oligosaccharides particuliers tels que les 1-cétoses à partir du sucre de canne.
