background and objectives: microbial caffeine removal is a green solution for treatment of caffeinated products and agro-industrial effluents. we directed this investigation to optimizing a bio-decaffeination process with growing cultures of pseudomonas pseudoalcaligenes through taguchi methodology which is a structured statistical approach that can be lowered variations in a process through de...

abstract extensive application of atrazine and its toxicity in environmental has attracted researcher attention for finding new degradation methods to this organic pollutant. biodegradation is one of most effective methods for removing atrazine. due to the importance of atrazine herbicide as an organic pollutant, a design carried out at factorial experiment in completely randomized design with ...

The broad and vague phenotypic definition allowed the genus Pseudomonas to become a dumping ground for incompletely characterized polarly flagellated, gram-negative, rod-shaped, aerobic bacteria, and a large number of species have been accommodated in the genus Pseudomonas. The 16S rRNA sequences of 128 valid and invalid Pseudomonas species, which included almost valid species of the genus Pseu...

Pseudomonas syringae pv. tomato race 1 strains have evolved to overcome genetic resistance in tomato. Here, we present the draft genome sequences of two race 1 P. syringae pv. tomato strains, A9 and 407, isolated from diseased tomato plants in California.

abstract atrazine biodegradation by bacteria is one of the most important aspects of bioremediation. atrazine can be degraded by various species of bacteria. bacteria use atrazine as nitrogen and carbon sources. the aim of this study was to determine atrazine degradation by pseudomonas fluorescence and pseudomonas aeruginosa. the experiment consisted of two pseudomonas bacteria, three levels of...

The in vitro susceptibilities of three Pseudomonas species (Pseudomonas aeruginosa, Pseudomonas putida, and Pseudomonas fluorescens) and Xanthomonas maltophilia to quinolone antimicrobial agents were determined. Several newer agents, particularly PD117558, PD117596, PD127391, sparfloxacin (AT-4140), A-56620, and temafloxacin, were active against Pseudomonas species. X. maltophilia isolates were...

The complete genome of the Pseudomonas aeruginosa bacteriophage PM105 is 39,593 bp long. The phage belongs to the B3 family of transposable Mu-like phages, as confirmed by the presence of bacterial DNA joined to the phage genome ends. PM105, together with other B3-like phages, form a newly arising species.

Fourteen quinolone-resistant Pseudomonas putida isolates were recovered from imported frozen shrimp sold in the United States. Two isolates harbored plasmids with qnrA and qnrB genes. PCR and DNA sequencing of quinolone resistance-determining regions identified novel substitutions in GyrA (His139→Glu and Thr128→Ala) and GyrB (Thr442→Asn, Gly470→Ala, and Ile487→Pro) and previously reported subst...

Here, we report the complete genome sequence for an isolate of Pseudomonas stutzeri that is highly competent for natural transformation. This sequence enables insights into the genetic basis of natural transformation rate variations and provides an additional data point for genomic comparisons across a ubiquitous and highly diverse bacterial species.
