Figure 3From: Automated DNA extraction platforms offer solutions to challenges of assessing microbial biofouling in oil production facilitiesDGGE analysis of bacterial 16S rRNA genes. DNA extracts from samples A, B and C extracted using the PowerBiofilm (P), QuickGene (Q) and Maxwell (M) were used as template for DGGE. Gene ruler 1 kb plus ladder (3 μl) was run in lanes 1, 5, 9, and 13.Back to article page
