The present paper investigates to examine the in vitro antibacterial activities of the chromium nanopartical which preparied by -green synthesis techniquesreduction of potassium dichromate solution with Arachis hypogaea leaf extract containing reducing sugars which act as reducing agent. Chromium nanoparticles were shown to be an effective control of two phytopathogenic bacteria, namely Erwinia...

Secondary metabolism in fluorescent pseudomonads is globally regulated by gacS, which encodes a membrane-bound sensor kinase, and gacA, which encodes a transcriptional response regulator. Spontaneous mutation in either gene blocked biosynthesis of the antimicrobial compounds hydrogen cyanide, 2,4-diacetylphloroglucinol, pyoluteorin, and pyrrolnitrin by the model biocontrol strain Pseudomonas fl...

INTRODUCTION P. fluorescens is an aerobic, Gram-negative bacillus related to Pseudomonas aeruginosa. Like other species of Pseudomonas, the organism is widespread in nature and is found in water, moist soil, and vegetation. Due to its low virulence, P. fluorescens is an infrequent cause of infections except for catheter-related bloodstream infections in cancer patients. From August 1, 2003 to M...

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...
