Shewanella ldhA gene highly expressed in E. coli

This composite part is used to constitutively express high levels of Shewanella oneidensis MR-1 fermentative lactate dehydrogenase NADH dependent ldhA (BBa_K2565000) in E. coli, locus tag SO_0968.

The left figure shows that the media with E. coli constitutively expressing ldhA contains more lactate than LB only. The right figure shows the amount of lactate in the media of cultures so that when Shewanella and E. coli are grown together there is more lactate in the media. The MG1655 strain of E. coli does not express the Shewanella ldhA gene.

This graph shows the voltage produced by microbial fuel cells (MFC) in 15 hours. The MFC with Shewanella and E. coli produced more voltage than Shewanella alone. The MFC with Shewanella and E. coli expressing Shewanella ldhA produced more consistent voltage than E. coli without Shewanella ldhA.
