摘要

Torulaspora delbrueckii starin IFO 0955 was examined with respect to its structural and serological properties of the cell wall mannan (Td-0955-M) Td-0955-M revealed significant reactivities with sera from a commercially available factor serum kit (Candida Check)in ELISA.Td-0955-M was investigated for its chemical structure by acetolysis under conventional and mild conditions.NMR and GC techniques were used as analytical techniques.The mannooligosaccharide fractions eluted from a Bio-Gel P-2 column were found to consist of Man(alpha-2)Man,M2 Man(alpha-2)Man(alpha-2)Man and Man(alpha1-2)Man M3 Man(alpha1-2)Man(beta1-2)Man(beta1-2)Man(alpha-2)Man M5 and a newmannoheptaose,which possesses the structure,Man(alpha1-2) Man(beta1-2)Man(beta1-2)Man(beta1-2)Man(alpha1-2) Man M7 The results of the inhibition ELISA showed that the M7 oligsaccharide significantly inhibited the reactivites in the Td-0955-M-factor serum systems.
