Binary culture biofilm formation by Stenotrophomonas maltophilia and Fusarium oxysporum

Binary culture biofilm formation by Stenotrophomonas maltophilia and Fusarium oxysporum was investigated using the recirculating modified Bobbins device batch culture system. Sequential attachment studies were carried out in the Bobbins device on PVC and glass surfaces, with each species as either the first or the second colonizer. Different surfaces had no significant effect on total numbers of S. maltophilia and F. oxysporum in the binary population biofilm, The attachment of the second colonizer was not influenced significantly by the previous attachment of the first colonizer. These results were confirmed using scanning electron micrographs.
