“…Considering that the membrane of Gram-positive bacteria has teichoic acids in its composition, which are basically formed by polyglycerol phosphate, poly(glucosyl phosphate), or polyribitol phosphate, the quantification of P content in the beads was used to confirm the occurrence of bacteria incorporation in the beads, , as shown in Supporting Information (SI-9, Table 4). OCB7%/QPVP-C5–5 showed the highest P content (559 ± 11 ppm), followed by OCB7%/QPVP-C5–12.5 (353 ± 16 ppm) and OCB7% (252 ± 17 ppm).…”

Cellulose beads with ∼3 mm of diameter and high circularity were obtained by dripping cellulose solutions (5, 6, and 7 wt %) dissolved in NaOH7%/urea12%, into HCl 2 M coagulation bath. Carboxylic groups were generated on beads surface through NaClO/NaClO2/TEMPO oxidation method, achieving total charge density of ∼0.77 mmol/g. Pristine (CB) and oxidized (OCB) beads were characterized by means of optical images analyses, scanning electron microscopy (SEM) and compression tests. Both types of beads, CB and OCB, were used as adsorbent for poly(4-vinyl-N-pentylpyridinium) bromide, QPVP-C5, a bactericidal agent. The adsorption of QPVP-C5 on CB and OCB was evaluated by means of FTIR-ATR, UV-vis, CHN elemental analyses, and X-ray photoelectron spectroscopy (XPS). The adsorbed amount of QPVP-C5 was remarkably higher on OCB than on CB due to ionic interactions. Desorption was less than 5%. The interaction between neat OCB or OCB coated and two different amounts of QPVP-C5 and Gram-positive bacteria Micrococcus luteus was assessed by changes in turbidimetry, SEM, and elemental analyses. Bacteria adsorbed on the surface of neat OCB and weakly QPVP-C5 coated OCB due to hydrogen bonding or ion-dipole interaction. Notorious bactericidal action was observed for OCB samples coated with large amount of QPVP-C5.

“…A5 and M. varians ATCC 29750 contain identical poly(a-D D-GlcpNAc phosphate) polymers (Chart 9). 55,56 For the latter strain, the structure of the linker region between the phosphoglycan and peptidoglycan was elucidated 57 and seemed to consist of a glycosyl phosphosaccharide unit D D-GlcNAc-(1-PO 3 H-6)-b-D D-MurNAc (where N-acetyl-D D-muramic acid is a part of the peptidoglycan). The same unit was found to be a part of the linker region in the cell wall of Bacillus pumilus AHU 1650 (Chart 10).…”

Purification, Characterization and Immunological Properties of the Serotype-specific Capsular Polysaccharide of Pasteurella haemolytica Serotype A7 Organisms

et al. 1986

The serotype-specific capsular polysaccharide from two strains of Pasteurella haemolytica serotype A7 organisms was purified and characterized by chemical analysis and by H and 3C NMR spectroscopy using one-and two-dimensional methods. The polymer has the repeating unit + 3)-~-2-acetamido-2-deoxygalactopyranose-( 1 + 3)-a-2-acetamido-2-deoxy-6-0-acetylglucopyranose-( 1 -phosphate+. It was immunogenic (capable of eliciting antibodies) for sheep. Chemical removal of 0-acetyl groups destroyed both the ability of the polymer to adhere to sheep erythrocytes at neutral pH and the ability to form immune precipitates with specific antisera. Studies using the protein A-gold technique in the electron microscope showed the polysaccharide to be peripherally localized on the bacterial surface.
