Pseudomonas aeruginosa mechanism

The mechanism of acquired resistance in Pseudomonas aeruginosa is different. Chromosomal mutations result in the increase of a specific outer membrane protein with a concomitant reduction in divalent cations. Polymyxins bind to the outer membrane at sites normally occupied by divalent cations, and therefore it is thought that a reduction in these sites will lead to decreased binding of the antibiotic with a consequent decreased susceptibility of the cell.

A combined method including TLC, HPLC, GC-MS and FTIR was employed for the study of the mechanism of the degradation of Navitan Fast Blue S5R by Pseudomonas aeruginosa. The culture medium containing the dye and its decomposition products was centrifuged and analysed by HPLC. The lyophilized supernatant was investigated by TLC... [Pg.392]

The stmcture of pyochelin (for a detailed bibliography, see (57)), a secondary siderophore of Pseudomonas aeruginosa and of Burkholderia cepacia was established (75) as 2-(2-o-hydroxyphenyl-2-thiazolin -yl)-3-methylthiazolidine-4-carboxylic acid. It consists of a mixture of two easily interconvertible stereoisomers (pyochelin I and II) differing in the configuration of C-2". They can be separated by chromatography, but in methanolic solution (not in DMSO) the equilibrium (ca. 3 1) is restored quickly. For a discussion of the mechanism of isomerization, see (57, 577).

Two different mechanisms for the formation of L-xyZo-2-hexulosonic acid (28) from L-sorbose (25) have been proposed, depending on the organism used for the fermentative oxidation. It was concluded280-283 that the metabolism of 25 by Pseudomonas aeruginosa IFO 3898 most probably follows the sequence 25 — L-idose (41) — L-idonic acid (42) — 28. Both 41 and 42 were isolated from the fermentation broth. With Gluconobacter melanogenus, it was concluded284-287 that 25 is... [Pg.108]
