MATERIALS AND METHODS Biological materials: The wild-type strain of Pseudomonas
putida used in this work was strain PRSl (ATCC 12633; strain 90 of STANIER, PALLERONI …

A simple but powerful technique for the enrichment of spontaneous mutant strains of
Pseudomonas putida is described. Repeated counter-selection of wild type cells in the …

Mutant Pseudomonas putida strains that produce constitutive levels of the beta-ketoadipate
uptake system are selected by the sequential transfer of cultures between mineral growth …

A novel experimental system to study mutation in starving bacteria was designed, relying on
the activation of a promoterless phenol degradation operon of Pseudomonas putida. The …

Two previously demonstrated linkage groups containing genes with catabolic function in
Pseudomonas putida have been shown to cotransduce with a third cluster of catabolic …

MATERIALS AND METHODS The strain of P. putrefaciens (no. 60) used throughout this
work was ob-tained fromDr. H. Wolochow, by whom itwas isolated (Wolochow, Thornton …

Some of the systems presently available for genetic engineering in Pseudomonas are
discussed. Their use for manipulations of its ability to degrade natural and xenobiotic …

The regulation and genetic control of the β-ketoadipate pathway in Pseudomonas
aeruginosa were investigated. The pattern of enzyme induction is apparently the same as in …

PSEUDOMONAS BACTERIOPHAGE8 Bacteriophages have significantly contributed to
many aspects of bacterial genetics. Bacteriophages infecting Pseudomonas can be isolated …
