Polysaccharides are large molecules composed of individual monosaccharide units. A common plant polysaccharide is starch, which is made up of many glucoses (in a polypeptide these are referred to as glucans).

Though polysaccharides are also biopolymers, it is not so common to talk of 'sequencing' a polysaccharide, for several reasons. Although many polysaccharides are linear, many have branches.

When do they form polysaccharides?
Quorum sensing may be involved in helping them turn on the synthesis of polysaccharides in proteins that glue the biofilm together. Then the bacteria grow just like they do in conventional cultures.
