Polysaccharides, Bacterial Categories.

	Bacterial Capsules - An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. Most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.
	Bambermycins - Antibiotic complex obtained from Streptomyces bambergiensis containing mainly Moenomycins A and C. They are used as feed additives and growth promoters for poultry, swine, and cattle.
	Prodigiozan - A polysaccharide extracted from Serratia marcescens and other bacteria. It activates enzymatic activity of macrophages and stimulates phagocytic processes.
