ABSTRACT: In a screening program for new microbial producers of fructan. Acetobacter species have been isolated from Egyptian soil sample, which produce fructan, when cultured on sucrose containing medium. The structure of a water insoluble fructan produced by this species has been determined by means of various spectroscopic methods. Comparison of the 13C-spectrum of the extracted fructan and natural inulin shows that former has a close structural similarity with the natural inulin backbone (C-1-C-6). Moreover, the extracted inulin differs from plant inulin with respect to its high crystallinity and purity. Acetobacter species could be therefore added as new microbial source for inulin.

KEYWORDS: Acetobacter sp; crystallinity; 13C-NMR; Fructan; Inulin
