Cell aggregation is associated with enzyme secretion strategies in marine polysaccharide-degrading bacteria

Martin Ackermann

Polysaccharide breakdown by bacteria requires the activity of enzymes that degrade polymers either intra- or extra-cellularly. The latter mechanism generates a localized pool of breakdown products that are accessible to the enzyme producers themselves as w ...
