Figure 6From: A seawater-based open and continuous process for polyhydroxyalkanoates production by recombinant Halomonas campaniensis LS21 grown in mixed substratesAnalysis of plasmid stability based on PCR assays of recombinant H. campaniensis LS21 grown under unsterile and continuous process for 65Â days. M: marker; lanes 1 to 24: 24 colonies were randomly selected from Petri disks grown with the day-65 recombinant H. campaniensis LS21 for the PCR assays. The primers were designed based on the conserved sequence of the backbone plasmid pBBRMCS1 with a target product of 1278Â bp.Back to article page
