Figure 3: Image of 1% agarose gel electrophoresis showing mcyA (518 bp) and mcyB (751 bp) PCR products amplified respective new primer pairs designed. Left: From a known M. aeruginosa (Hartbeespoort Dam). Right: From the investigated Microcystis spp (Phakalane pond effluent). [Other lanes: 16S-rRNA (≈500 bp)=Positive control; M=Standard DNA ladder (1kb) and –ve ctrl=Negative control)].
