2,4-Diacetylphloroglucinol or Phl [1] [2] is a natural phenol found in several bacteria: . Specific strains of the Gram-negative bacterium Pseudomonas fluorescens. [3] This compound is found to be responsible for the antiphytopathogenic [4] and biocontrol [5] properties in these strains.
Pseudomonas fluorescens has multiple flagella, an extremely versatile metabolism, and can be found in the soil and in water.It is an obligate aerobe, but certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration.
Pyrrolnitrin (PRN [1]) is a naturally occurring phenylpyrrole fungicide. [2] Pseudomonas and Burkholderia species produce pyrrolnitrin from tryptophan as secondary metabolite. [3] [4] It is believed that the antifungal properties come from inhibition of electron transport system.
Pseudomonas protegens are widespread Gram-negative, plant-protecting bacteria. [1] Some of the strains of this novel bacterial species (CHA0 and Pf-5, for example) previously belonged to P. fluorescens. They were reclassified since they seem to cluster separately from other fluorescent Pseudomonas species.
The type that most commonly infects humans is Pseudomonas aeruginosa, which can lead to infections in the blood, lungs or other parts of the body, the CDC says. The agency points out that ...
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 348 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. [4]
This is a list of fungicides. These are chemical compounds which have been registered as agricultural fungicides . The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [ 1 ]
Although many (>100) forms of pyoverdine have been isolated and studied, they all have certain characteristics in common. Each pyoverdine molecule has three parts: a dihydroxyquinoline core, a 6-14 amino acid peptide that varies among strains, and a side chain (usually composed of a 4-5 carbon α-ketoacid from the Krebs/citric acid cycle).
