Cyanide production by Pseudomonas fluorescens and Pseudomonas aeruginosa.
Of 200 water isolates screened, five strains of Pseudomonas fluorescens and one strain of Pseudomonas aeruginosa were cyanogenic. Maximum cyanogenesis by two strains of P. fluorescens in a defined growth medium occurred at 25 to 30 degrees C over a pH range of 6.6 to 8.9. Cyanide production per cell was optimum at 300 mM phosphate. A linear relationship was observed between cyanogenesis and the...
متن کاملLon protease influences antibiotic production and UV tolerance of Pseudomonas fluorescens Pf-5.
Pseudomonas fluorescens Pf-5 is a soil bacterium that suppresses plant pathogens due in part to its production of the antibiotic pyoluteorin. Previous characterization of Pf-5 revealed three global regulators, including the stationary-phase sigma factor sigma(S) and the two-component regulators GacA and GacS, that influence both antibiotic production and stress response. In this report, we desc...
متن کاملAluminum detoxification in Pseudomonas fluorescens is mediated by oxalate and phosphatidylethanolamine.
13C NMR studies with aluminum (Al)-stressed Pseudomonas fluorescens revealed that the trivalent metal was secreted in association with oxalate and phosphatidylethanolamine (PE). These moieties were observed in the insoluble pellet obtained upon incubation of these resting cells in the presence of either Al-citrate or citrate. This extrusion process was concomitant with the utilization of either...
متن کاملPseudomonas 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 کاملMultiple-Level Regulation of 2,4-Diacetylphloroglucinol Production by the Sigma Regulator PsrA in Pseudomonas fluorescens 2P24
BACKGROUND Pseudomonas fluorescens 2P24 is a rhizospheric bacterium that aggressively colonizes the plant roots. It produces the antibiotic 2,4-diacetylphoroglucinol (2,4-DAPG), which contributes to the protection of various crop plants against soil borne diseases caused by bacterial and fungal pathogens. The biosynthesis of 2,4-DAPG is regulated at the transcriptional level in the expression o...
