TextSentencer_T1 0-52 Sentence denotes Ultrasonic irradiation of bacterial polysaccharides.
TextSentencer_T2 53-137 Sentence denotes Characterization of the depolymerized products and some applications of the process.
TextSentencer_T3 138-295 Sentence denotes Ultrasonic irradiation (u.i.) has been used to depolymerize biopolymers including DNA, dextran, and the Vi capsular polysaccharide from Citrobacter freundii.
TextSentencer_T4 296-459 Sentence denotes Representative bacterial polysaccharides were subjected to u.i. and the effect of this energy upon their molecular weight and chemical structure was characterized.
TextSentencer_T5 460-706 Sentence denotes U.i. depolymerized a neutral polysaccharide (dextran) and acidic polysaccharides containing either a phosphoric diester linkage [Haemophilus influenzae type b (Hib) and pneumococcus types 6A and 6B] or a uronic acid moiety (pneumococcus type 9N).
TextSentencer_T6 707-830 Sentence denotes Prolonged u.i. depolymerized all the polysaccharides to a finite and similar molecular mass (approximately 50 000 daltons).
TextSentencer_T7 831-961 Sentence denotes The rate of depolymerization induced by u.i. depended on the viscosity of the solvent and the concentration of the polysaccharide.
TextSentencer_T8 962-1122 Sentence denotes 13C-N.m.r. data of the native Hib polysaccharide and its depolymerized products indicated that u.i. did not alter the chemical structure of the repeating units.
TextSentencer_T9 1123-1347 Sentence denotes Determination of the monophosphate terminal residues by 31P-n.m.r. spectroscopy and of the reducing end groups by the Park-Johnson reaction indicated that both the phosphoric diester and the glycosidic linkages were cleaved.
TextSentencer_T10 1348-1568 Sentence denotes The Vi polysaccharide, prepared as an investigational vaccine, could not be analyzed for its chemical structure by 13C-n.m.r. spectroscopy owing to its high viscosity but depolymerization by u.i. permitted this analysis.
TextSentencer_T11 1569-1792 Sentence denotes The finite molecular weight of the products observed after prolonged u.i. is best explained by the postulation that the mechanical torque necessary to rupture the linkages is dependent upon the length of the polysaccharide.
TextSentencer_T12 1793-1984 Sentence denotes The method of u.i. for depolymerization is useful for the preparation of homogeneous, low-molecular-weight polysaccharides without alteration of the chemical structure of the repeating units.
T1 0-52 Sentence denotes Ultrasonic irradiation of bacterial polysaccharides.
