Five bacteria (Pseudomonas fluorescens, P. fluorescens subgroup G strain 2, P. marginalis, P. putida subgroup B strain 1 and P. syringae strain 1) and three fungi (Penicillium brevicompactum, P. solitum strain 1 and Trichoderma atroviride) were evaluated to determine their promoting effect on the growth of mature healthy tomato plants grown under hydroponic conditions. P. putida and T. atroviri...

The recombinant Pseudomonas putida strain CB1-9, which acquired the ability to grow on chlorobenzenes, contains a 33-kilobase (kb) plasmid (pKFL3) which lacked homology to an indigenous 15-kb plasmid (pKFL1) in Pseudomonas alcaligenes C-0 parent but was homologous to a 55-kb plasmid (pKFL2) from the P. putida R5-3 parent. Chromosomal DNA of P. alcaligenes C-0 hybridized to probes prepared from ...

Derivatives of the Pseudomonas aeruginosa plasmid R91-5, loaded with the transposon Tn501, were transferred to P. putida PPN. Over 90% of exconjugants, which arose at a frequency of ca. 10(-6) per donor cell, exhibited high-frequency (greater than 10(-2) per donor cell) polarized transfer of chromosomal markers. In one instance it was demonstrated by transduction that the plasmid had been inser...

Branched-chain oxo acid dehydrogenase was purified from Pseudomonas aeruginosa strain PAO with the objective of resolving the complex into its subunits. The purified complex consisted of four proteins, of Mr 36,000, 42,000, 49,000 and 50,000. The complex was resolved by heat treatment into the 49,000 and 50,000-Mr proteins, which were separated by chromatography on DEAE-Sepharose. The 49,000-Mr...

Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 13, No. 4, April 2007 669 levels of susceptibility because the MIC50 was only 1 dilution below the current breakpoint (7,8). Aztreonam resistance could not be transferred by conjugation between IMP-1–producing (aztreonam-resistant) P. putida and P. aeruginosa (2) and is not associated with a transposon carrying blaVIM-2 (6). No evidence of e...

Only the fluorescent pseudomonads, Pseudomonas aeruginosa, P. putida, and P. fluorescens, were sensitive to pyocins produced from P. aeruginosa.

The basic mechanisms underlying solvent tolerance in Pseudomonas putida DOT-T1E are efflux pumps that remove the solvent from bacterial cell membranes. The solvent-tolerant P. putida DOT-T1E grows in the presence of high concentrations (e.g., 1% [vol/vol]) of toluene and octanol. Growth of P. putida DOT-T1E cells in LB in the presence of toluene supplied via the gas phase has a clear effect on ...

Horizontal gene transfer is a fundamental process in bacterial evolution that can accelerate adaptation via the sharing of genes between lineages. Conjugative plasmids are the principal genetic elements mediating the horizontal transfer of genes, both within and between bacterial species. In some species, plasmids are unstable and likely to be lost through purifying selection, but when alternat...
