to evaluate the effects of pgpr foliar spraying on forage and grain yield of forage sorghum (var. speedfeed), a farm experiment was conducted in research farm of college of agriculture, university of tehran in 2009. the experimental design consisted of a randomized complete blocks consisting of 17 treatments in every block. in this research, the effect of foliar application of 16 different stra...
When iron-starved, the Mn(II)-oxidizing bacteria Pseudomonas putida strains GB-1 and MnB1 produce pyoverdines (PVDGB-1 and PVDMnB1), siderophores that both influence iron uptake and inhibit manganese(II) oxidation by these strains. To explore the properties and genetics of a PVD that can affect manganese oxidation, LC-MS/MS, and various siderotyping techniques were used to identify the peptides...
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 ...
BACKGROUND The substitution of plastics based on fossil raw material by biodegradable plastics produced from renewable resources is of crucial importance in a context of oil scarcity and overflowing plastic landfills. One of the most promising organisms for the manufacturing of medium-chain-length polyhydroxyalkanoates (mcl-PHA) is Pseudomonas putida KT2440 which can accumulate large amounts of...
The rpoS gene encodes the sigma factor which was identified in several gram-negative bacteria as a central regulator during stationary phase. rpoS gene regulation is known to respond to cell density, showing higher expression in stationary phase. For Pseudomonas aeruginosa, it has been demonstrated that the cell-density-dependent regulation response known as quorum sensing interacts with this r...
Cytochrome P-450cam catalyzes the stereospecific methylene hydroxylation of camphor to form 5-exohydroxycamphor and is encoded by the camC gene on the CAM plasmid of Pseudomonas putida, ATCC 17453. The cytochrome P-450cam structural gene has been cloned by mutant complementation in P. putida (Koga, H., Rauchfuss, B., and Gunsalus, I. C. (1985) Biochem. Biophys. Res. Commun. 130, 412-417). We re...
A study was conducted to determine whether competition for inorganic nutrients affects the biodegradation of mixtures of substrates. Little benzylamine was mineralized by Pseudomonas putida in solutions with no added P, but the substrate was degraded if the medium contained 100 nM P. The enhancement by P addition did not occur if the medium also contained caprolactam and a caprolactam-utilizing...
This report describes the isolation and preliminary characterization of a 5.0-kilobase-pair (kbp) EcoRI DNA restriction fragment carrying the catBCDE genes from Acinetobacter calcoaceticus. The respective genes encode enzymes that catalyze four consecutive reactions in the catechol branch of the beta-ketoadipate pathway: catB, muconate lactonizing enzyme (EC 5.5.1.1); catC, muconolactone isomer...
The genes encoding flavin mononucleotide-containing oxidoreductases, designated xenobiotic reductases, from Pseudomonas putida II-B and P. fluorescens I-C that removed nitrite from nitroglycerin (NG) by cleavage of the nitroester bond were cloned, sequenced, and characterized. The P. putida gene, xenA, encodes a 39,702-Da monomeric, NAD(P)H-dependent flavoprotein that removes either the termina...
