Genomotyping of Pseudomonas putida strains using P. putida KT2440-based high-density DNA microarrays: implications for transcriptomics studies

Valerolactone from Levulinate in Pseudomonas putida KT2440

Amino acid racemization in Pseudomonas putida KT2440.

D-Amino acids have been shown to play an increasingly diverse role in bacterial physiology, yet much remains to be learned about their synthesis and catabolism. Here we used the model soil- and rhizosphere-dwelling organism Pseudomonas putida KT2440 to elaborate on the genomics and enzymology of d-amino acid metabolism. P. putida KT2440 catabolized the d-stereoisomers of lysine, phenylalanine, ...

Construction and characterization of nitrate and nitrite respiring Pseudomonas putida KT2440 strains for anoxic biotechnical applications.

Pseudomonas putida KT2440 is frequently used in biotechnical research and applications due to its metabolic versatility and organic solvent resistance. A major drawback for a broad application is the inability of the bacterium to survive and grow under anoxic conditions, which prohibits the production of oxygen-sensitive proteins and metabolites. To develop a P. putida strain, which is able to ...

Conversion of levoglucosan and cellobiosan by Pseudomonas putida KT2440

Pyrolysis offers a straightforward approach for the deconstruction of plant cell wall polymers into bio-oil. Recently, there has been substantial interest in bio-oil fractionation and subsequent use of biological approaches to selectively upgrade some of the resulting fractions. A fraction of particular interest for biological upgrading consists of polysaccharide-derived substrates including su...

Molecular characterization of Pseudomonas putida KT2440 rpoH gene regulation.

The rpoH gene of Pseudomonas putida KT2440 encoding the heat-shock sigma factor sigma(32) was cloned and sequenced, and the translated gene product was predicted to be a protein of 32.5 kDa. The unambiguous role of the gene as a sigma factor was confirmed because the cloned P. putida gene complemented the growth defect, at 37 and 42 degrees C, of an Escherichia coli rpoH mutant strain. Primer e...
