Construction and comparison of different vehicles for heterologous gene expression in Zymomonas mobilis.

ABSTRACT: Zymomonas mobilis has the potential to be an optimal chassis for the production of bulk chemicals derived from pyruvate. However, a lack of available standardized and characterized genetic tools hinders both efficient engineering of Z. mobilis and progress in basic research on this organism. In this study, a series of different shuttle vectors were constructed based on the replication mechanisms of the native Z. mobilis plasmids pZMO1, pZMOB04, pZMOB05, pZMOB06, pZMO7 and p29191_2 and on the broad host range replication origin of pBBR1. These plasmids as well as genomic integration sites were characterized for efficiency of heterologous gene expression, stability without selection and compatibility. We were able to show that a wide range of expression levels could be achieved by using diff
