Figure 2From: Design and evaluation of 16S rRNA sequence based oligonucleotide probes for the detection and quantification of Comamonas testosteroni in mixed microbial communitiesAgarose gel showing PCR products obtained using the primer pair CteA1 from the testosterone enrichment cultures and the isolates grown on testosterone plates. M: 100 bp ladder, +ve: positive control (C. testosteroni genomic DNA), AS: activated sludge inoculum, E1: first enrichment step, E2: second enrichment step, I1–I5: isolates, -ve: negative control (no template DNA).Back to article page
