Flavobacterium johnsoniae UW101

Names Flavobacterium johnsoniae UW101
Accession numbers NC_009441
Background Flavobacterium johnsoniae (formerly Cytophaga johnsonae ) is an aerobic Gram-negative bacterium that is commonly found in soil and freshwater. It belongs to the group of bacteria known as the 'Bacteroidetes' which are also referred to as the 'Cytophaga-Flavobacterium-Bacteroides' group. F. johnsoniae rapidly digests chitin and many other macromolecules. F. johnsoniae does not secrete large amounts of soluble chitinases, instead, direct contact of cells with insoluble chitin is required for efficient utilization. Some other Bacteroidetes such as the cellulose digesting Cytophaga hutchinsoni , also require direct contact with their insoluble substrates to digest them. Like many Bacteroidetes, F. johnsoniae exhibits the ability to move rapidly over surfaces by a process known as gliding motility. F. johnsoniae has become a model system for studies of this unusual form of motility. Gliding may be important in digestion of insoluble polymers such as chitin. All nonmotile mutants of F. johnsoniae display defects in chitin utilization, suggesting that gliding and chitin utilization may be related. (EBI Integr8)
