description | La presente invención revela un método de obtención de 1-kestosa, a escala industrial, mediante el empleo de una fructosiltransferasa (FTF) recombinante, aislada de Festuca arundinacea, expresada constitutivamente en una levadura hospedera no sacarolítica.En la invenvión, la FTF recombinante tipo sacarosa:sacarosa 1-fructosiltransferasa (1-SSTrec) se produce de forma constitutiva, estable y en altos niveles, tanto en el sobrenadante como en el sedimento celular del cultivo de una cepa de Pichia pastoris. Por tanto, también se provee un método para la obtención de 1-SST a escala industrial. La enzima recombinante resultante se emplea para la producción enzimática masiva de fructoligosacáridos (FOS), específicamente de 1-kestosa, a partir de la sacarosa.El método de la presente invención permite conversiones superiores al 55% en FOS, donde la 1-kestosa está representada en más de un 90%.
The present invention discloses an industrial scale method to obtain 1-kestose by the use of a recombinant fructosyltransferase (FTF), isolated from Festuca arundinacea, expressed constitutively in a non-saccharolytic yeast. In this invention, the recombinant FTF type sucrose:sucrose 1-fructosyltransferase (1-SSTrec) is produced constitutively, stable and at high yield, both in the culture supernatant and in intact cells of the host Pichia pastoris. Hence, the invention additionally provides a method for 1-SST production at industrial scale. The recombinant enzyme is then used for mass production of short-chain fructooligosaccharides (FOS), specifically 1-kestose, from sucrose. The method of the present invention establishes conditions that allow conversion rates where the synthesized FOS constitute above 55% (w/w) of the total sugars in the reaction mixture and the 1-kestose content reaches values higher than 90% (w/w) of the total FOS fraction. |
