Turning on Shewanella Mtr Pathway Genes

Shewanella genus is very famous for electron transfer in microbe fuel cells and bioremediation of heavy metals through the Mtr pathway. A potential way to enhance the electron genesis ability of Shewanella is to express exogenous mtr genes via recombinant DNA technology.
In this study, Professor I-Son Ng and her co-works at the Department of Chemical Engineering, National Cheng Kung University (Tainan) successfully constructed an expression system for the first time, based on pLacI promoter and repB ori in Shewanella oneidensis MR-1, which turns on the expression of different foreign genes constitutively in Shewanella. The recombinant strains had higher ferric reductase activity than the wild type. The highest enzymatic activity achieved in genetic Shewanella with mtrC gene was 508 U/L, 1.5-fold higher than that of wild strain. Furthermore, the plasmids were stable up to 90 generations.

Aims and scope

Bioresources and Bioprocessing (BIOB) is a peer-reviewed open access journal published under the brand SpringerOpen. BIOB aims at providing an international academic platform for exchanging views on and promoting research to support bioresource development, processing and utilization in a sustainable manner. As an application-oriented research journal, BIOB covers not only the application and management of bioresource technology but also the design and development of bioprocesses that will lead to new and sustainable production processes.

BIOB publishes original and review articles on most topics relating to bioresource and bioprocess engineering, including:

Biochemical and microbiological engineering
Biocatalysis and biotransformation
Biosynthesis and metabolic engineering
Bioprocess and biosystems engineering
Bioenergy and biorefinery
Cell culture and biomedical engineering
Food, agricultural and marine biotechnology
Bioseparation and biopurification engineering
Bioremediation and environmental biotechnology
