Determination of pyoverdine, the fluorescent pigment of pseudomonads, in frozen whole egg.
The Federal Food, Drug, and Cosmetic Act of 1938 defines as adulterated any food that is composed in whole or in part of a filthy or decomposed substance. Objective laboratory and field tests for detection of decomposed products are always advisable to supplement organoleptic examinations. In any product where organoleptic tests fail because decomposition is masked by any means, objective tests...
متن کاملCharacterization of a pigment from a pseudomonad.
The chloroform-soluble pigments of various pseudomonads have been found to be phenazine derivatives (Clemo & Daglish, 1950; Hillemann, 1938; Kogl & Postowsky, 1930; Kluyver, 1956; Haynes et al. 1956), whereas the constitutions of water-soluble fluorescent pigments of various pseudomonads are not well known. This has been mainly due to the failure of previous attempts to obtain the pigments in a...
متن کاملIdentification of Some Molecular Traits in Fluorescent Pseudomonads with Antifungal Activity
We assessed a collection of 47 fluorescent Pseudomonas spp., some with known biological control activity against certain soil-borne phytopathogenic fungi such as, Macrophomina phaseolina, Rhizoctonia solani, Phytophthora nicotianae var. parasitica, Pythium sp. and Fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, HCN and protease. The resu...

KRAFT, A. A. (Iowa State University, Ames), AND J. C. AYRES. Production of fluorescence on packaged chicken. Appl. Microbiol. 9:549-553. 1961.-Development of fluorescence caused by pseudomonads proliferating on packaged chicken was determined by examination of the poultry under ultraviolet light and by measurements of absorption spectra. Asparagine broth inoculated with organisms from chicken s...
متن کاملIdentification and characterization of novel pyoverdine synthesis genes in Pseudomonas aeruginosa.
Fluorescent pseudomonads secrete yellow-green siderophores named pyoverdines or pseudobactins. These comprise a dihydroxyquinoline derivative joined to a type-specific peptide and, usually, a carboxylic acid or amide. In Pseudomonas aeruginosa strain PAO1, six genes that encode proteins required for pyoverdine synthesis (pvd genes) have been identified previously. Expression of all of these gen...
