Abstract
Listeria monocytogenes is a bacterial species that can contaminate a variety of food products and cause foodborne illness. Previous research has found that L. monocytogenes may form enhanced biofilms with Ralstonia insidiosa, a bacterial species commonly found in potable water. This study investigated the abilities of L. monocytogenes and R. insidiosa to produce enhanced biofilms when grown in co-culture. Our results suggest that these species do form enhanced biofilms with one another and that this enhancement is not fully dependent on direct cell-to-cell contact, as enhanced biofilm formation was observed when one species was grown with supernatant from the other.
