Glycopolymers of two types were isolated from the cell wall of Lactococcus lactis BIM B-1024 by stepwise extraction with cold and hot 10% CCl3 CO2 H and separated by anion-exchange gel chromatography. The following structures of the glycopolymers were established by sugar analysis, dephosphorylation with 48% HF, 1D and 2D NMR spectroscopy, and ESI-MS:
Polysaccharides with the same or similar structures to PSI have been found earlier in various Lactobacillus species, whereas, to our knowledge, the structure of PSII is new.
