Bacteria isolated from marine sponges found off the coast of Rio de Janeiro, Brazil, were screened for the production of antimicrobial substances. We report a new Pseudomonas putida strain (designated P. putida Mm3) isolated from the sponge Mycale microsigmatosa that produces a powerful antimicrobial substance active against multidrug-resistant bacteria. P. putida Mm3 was identified on the basi...

Purified catabolic ornithine carbamoyltransferase of Pseudomonas putida and anabolic ornithine carbamoyltransferase (argF product) of Escherichia coli K-12 were used to prepare antisera. The two specific antisera gave heterologous cross-reactions of various intensities with bacterial catabolic ornithine carbamoyltransferases formed by Pseudomonas and representative organisms of other bacterial ...

We describe the draft genome sequence of Pseudomonas putida strain LS46, a novel isolate that synthesizes medium-chain-length polyhydroxyalkanoates. The draft genome of P. putida LS46 consists of approximately 5.86 million bp, with a G+C content of 61.69%. A total of 5,316 annotated genes and 5,219 coding sequences (CDS) were identified.

Ceftizoxime, a new cephalosporin, was active against Pseudomonas cepacia, Flavobacterium meningosepticum, Alcaligenes faecalis, and Acinetobacter calcoaceticus and was more potent against Pseudomonas aeruginosa and Pseudomonas putida than was carbenicillin.

Pseudomonas species are opportunistic pathogens with implications in a wide range of diseases including cystic fibrosis and sickle cell anaemia. Because of their status as multidrug resistant (MDR) and extremely drug resistant (XDR) bacteria Pseudomonas species represent a threat to public health. Prevalence, antibiogram and associated antibiotic resistant genes of Pseudomonas species isolated ...

RNase R is a 3'-5' highly processive exoribonuclease that can digest RNAs with extensive secondary structure. We analyzed the global effect of eliminating RNase R on the Pseudomonas putida transcriptome and the expression of the rnr gene under diverse conditions. The absence of RNase R led to increased levels of many mRNAs, indicating that it plays an important role in mRNA turnover.

Pseudomonas putida F1 and Pseudomonas sp. strain JS150 initiate toluene degradation by incorporating molecular oxygen into the aromatic nucleus to form cis-1,2-dihydroxy-3-methylcyclohexa-3,5-diene. When toluene-grown cells were incubated with 2- and 3-nitrotoluene, the major products identified were 2- and 3-nitrobenzyl alcohol, respectively. The same cells oxidized 4-nitrotoluene to 2-methyl-...
