It is assumed that plant growth regulators produced by beneficial Background bacterial species could also influence plant growth. IAA is a major plant growth regulator responsible for stimulation of plant growth. There are several microorganisms which are naturally responsible for Ltryptophan metabolism. : In total, 56 indigenous morphologically distinct isolates from rice Methods roots were se...

Escherichia coli argE and argH gene products were detected in Pseudomonas fluorescens argH122 carrying the E. coli F110 plasmid.

We report here the application of single-molecule real-time sequencing for determining the entire genome structure of the cyanotroph Pseudomonas fluorescens NCIMB 11764.

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

To decontaminate dredged harbor sediments by bioremediation or electromigration processes, adding biosurfactants could enhance the bioavailability or mobility of contaminants in an aqueous phase. Pure amphisin from Pseudomonas fluorescens DSS73 displays increased effectiveness in releasing polycyclic aromatic hydrocarbons (PAHs) strongly adsorbed to sediments when compared to a synthetic anioni...

Certain 2,4-diacetylphloroglucinol-producing strains of Pseudomonas fluorescens colonize roots and suppress soilborne diseases more effectively than others from which they are otherwise phenotypically almost indistinguishable. We recovered DNA fragments present in the superior colonizer P. fluorescens Q8r1-96 but not in the less rhizosphere-competent strain Q2-87. Of the open reading frames in ...

The Pseudomonas fluorescens YT101 gene narG, which encodes the catalytic alpha subunit of the respiratory nitrate reductase, was disrupted by insertion of a gentamicin resistance cassette. In the Nar(-) mutants, nitrate reductase activity was not detectable under all the conditions tested, suggesting that P. fluorescens YT101 contains only one membrane-bound nitrate reductase and no periplasmic...

The present experiment was conducted in the Department of Fruit Science, College Horticulture and Forestry, Pasighat, Arunachal Pradesh, during year 2021-2022. trial laid out using two factorial RBD replicated thrice. Assam lemon trees were pruned at 25% (P1), 50% (P2) from top apex soil drenching with Pseudomonas fluorescens @ 90g/plant (B1), Trichoderma (B2), Azotobacter 15g/plant (B3) a comb...

A new apparatus was developed for measuring changes in E(h), pH, and cell numbers. With this apparatus, the relationships of these parameters were studied at initial E(h) levels of 200 and 40 mv (pH 7.0), by using Clostridium perfringens and Pseudomonas fluorescens. One of the strains of C. perfringens grew more luxuriantly at the higher E(h), in the presence of small quantities of oxygen, than...
