Pseudomonas fluorescens
nas incognita have been previously described as being able to utilize citronellol, geraniol, and linalool (3, 6). Recently, a 50-megadalton (MDa) plasmid has been associated with the degradation of geraniol (9). In this report we describe the isolation of a Pseudomonas fluorescens s train capable of utilizing linalool as a sole carbon and energy source and demonstrate the presence of a transmis...
متن کاملThe kynureninase of Pseudomonas fluorescens.
Kotake and Nakayama (1) observed the conversion of kynurenine to anthranilic acid and alanine by a mammalian liver extract. Subsequently the enzyme responsible for this reaction in the mammal was partly purified (2,3) and the enzyme, prepared from vitamin Be-deficient animals, was shown to require pyridoxal phosphate for its maximal activity (2). During an investigation of tryptophan metabolism...
متن کاملCharacterization of a Protease from a Psychrotroph, Pseudomonas fluorescens 114.
A psychrotrophic bacterium isolated from river sediment was identified as Pseudomonas fluorescens 114. It grew at 0 degrees C and optimally at 20 degrees C. The bacterium produced a protease with a molecular weight of 47,000, which was stable in the pH range of 5 to 9 and worked optimally between pH 6.5 and 10. Activity was optimal at 35 degrees C and was lost immediately at 50 degrees C and af...
متن کاملIsolation of secondary metabolites from Pseudomonas fluorescens and its Characterization
Twenty Pseudomonas fluorescens strains were isolated from rice growing soil samples and characterized. One of the P.fluorescens isolated and identified from the dual culture test. It was fermented for secondary metabolite in a small scale and extracted with ethyl acetate. The isolated metabolite tested against rice fungal pathogens. The structure of the compound was elucidated by high-resolutio...
متن کاملCharacterization and lytic activity of Pseudomonas fluorescens phages from sewage
Pseudomonas fluorescens phages from sewage were tested against P. fluorescens isolates of soil and sewage. The phages were characterized as to host range, morphology, structural proteins and genome fingerprint. Of the seven phages isolated, one was found to be abundant in sewage (5.9×10(7) pfu/mL), having broad host range, and distinct protein and DNA profile when compared to the other six phag...
