AbstractGene transfer systems were developed in Rubrivivax (Rx.) gelatinosus S1. First, a system for conjugative transfer of mobilizable plasmids from Escherichia coli to Rx. gelatinosus S1 was established. Secondly, optimal conditions for the transformation of Rx. gelatinosus S1 by electroporation were determined. A ��puf strain was constructed. Complementation with the puf operon from a wild-type...
Rubrivivax gelatinosus is a facultative phototrophic non-sulfur bacterium belonging to the β subclass of the purple bacteria. A terbutryn-resistant mutant of R. gelatinosus has been isolated and characterized. Increased resistance levels to terbutryn (300-fold), atrazine (6-fold) and o-phenanthroline (3-fold) were observed for the mutant compared with wild type. Sequence analysis of the mutant...
