Abstract
Shuttle vectors useful for the genetic manipulation of several moderately halophilic bacteria have been constructed. These vectors are based on the minimal replicon of pCM1, a cryptic plasmid fromChromohalobacter marismortui,combined with the useful properties of pUC18 plasmid (i.e., small size, high copy number, multiple cloning sites,lacZfragment), as well as with the trimethoprim resistance gene as a selection marker for moderate halophiles. These vectors can be efficiently transferred by RP4-mediated conjugation fromEscherichia colito the moderate halophilesChromohalobacter marismortui, Deleya halophila, Halomonas elongata, Halomonas subglaciescola,andVolcaniella eurihalina.
