Variation in 16S rRNA gene fingerprints between sample types (Biofilm, SML and water column), for March 2009 (summer); (a) Composite DGGE image standardised for gel-to-gel comparison using BioNumerics, (b) Multidimensional scaling (MDS) plot based on relative band intensity from composite DGGE profile.
