Production of a single cyclic type of fructooligosaccharide structure by inulin-degrading Paenibacillus sp. LX16 newly isolated from Jerusalem artichoke root.

Yao Z, Guo J, Tang W, Sun Z, Hou Y, Li X - Microb Biotechnol (2016)

Bottom Line: The predominant cellular fatty acids were anteiso-C15:0, C16:0 and anteiso-C17:0.The FOS was identified as a cyclofructooligosaccharide with a degree of polymerization of 6.Such homology in inulin degradation products may be beneficial for the functional FOS production.

mbt212358-fig-0003: ESI‐MS analysis of the inulin degradation products. (A) Electrospray ionization spectra of the parent FOS; (B) electrospray ionization spectra of the fragmented FOS; (C) ways in which the FOS could be fragmented.

Mentions: The inulin degradation product from the culture supernatant of Paenibacillus sp. LX16 was analysed by electrospray ionization mass spectrometry (ESI‐MS) in negative ion mode (Fig. 3). The molecular weight of the inulin degradation product was determined to be 972, as calculated from the m/z 971 ion corresponding to the deprotonated ion [G‐H]− in the negative mode of ESI‐MS (Fig. 3A). The ions at m/z 179 (F), m/z 323 (F2), m/z 485 (F3) and m/z 647 (F4) were also observed when the ion at m/z 971 (F6) were further selected for MS2 fragmentation (Fig. 3B). The FOS structure and the presumed way to fragment FOS are shown in Fig. 3C.
