Figure 3From: Functional profiling of mercuric reductase (mer A) genes in biofilm communities of a technical scale biocatalyzerSeparation of merA amplicons (primers GC-merAf and merAr) on a silver-stained TGGE gel. All strains showed clearly distinguishable mer A-TGGE fingerprints. See Fig. 5 for strain identification. M, mix of PCR products from all eight strains.Back to article page
