pDNA topological analyses. a Agarose gel electrophoresis images of pDNA samples through the cultivation time; b Chip electrophoresis electropherograms; c virtual gel agarose electrophoresis images of pDNA samples from the end of the cultures. SC indicates the pDNA supercoiled fraction; M denotes DNA markers; 1 and 2 indicate the two major pDNA populations found
