Protein-polysaccharide and Lipopolysaccharides

Peptidoglycan-polysaccharide (PG-PS) fragments are isolated from S. pyogenes [34] to study the reactivation of induced inflammation. Peptidoglycan polymers [35] are isolated from bacterial cell walls. The peptidoglycan and related polymers are obtained from penicillin treated Bacillus subtilis [36], Streptococcus pyogenes, Staphylcoccus epidermis, Nocardia corynebacteriodes and Streptomyces 

O-specific polymers of lipopolysaccharide are isolated and characterized from Pseudomonas cepacia [42]. Lipopolysaccharide is produced from Salmonella typhimurium, Raistonia solanacearum, Helicobacter pylori [32, 14, 43, 44]. Lipopolysaccharides are synthesized biologically by Salmonella typhimurium [45].
