Abstract: | The objective of this paper was to understand the detachment of multispecies biofilm caused by abrasion. By submitting a biofilm
to different abrasion strengths (collision of particles), stratification of biofilm cohesion could be highlighted and related
to stratification of biofilm bacterial communities using the PCR-SSCP fingerprint method. The biofilm comprised a thick top
layer, weakly cohesive and composed of one dominant species, and a thin basal layer, strongly cohesive and composed of a more
diverse population. These observations suggest that microbial composition of biofilms may be an important parameter in understanding
biofilm detachment. |
