Production and utilization of pyochelin by clinical isolates of Pseudomonas cepacia.
Forty-three Pseudomonas cepacia isolates were screened for the production of pyochelin. Twenty-one (49%) produced pyochelin, and 22 (51%) were pyochelin negative. Of the 21 strains producing pyochelin, 18 were from patients with severe infections, 11 of which resulted in death. Of the 22 strains which did not produce pyochelin, 13 were from patients with mild or moderate infections. Pyochelin p...
متن کاملExotoxin production by clinical isolates of pseudomonas aeruginosa.
Seventy-five consecutive clinical Pseudomonas aeruginosa isolates were tested for in vitro exotoxin production. Exotoxin was demonstrated in culture filtrates biologically, by its ability to produce characteristic dermonecrotic lesions in guinea pigs, and seriologically, by counterimmunoelectrophoresis (CIE) with rabbit antiserum elicited with purified exotoxin. By these two methods, exotoxin w...
متن کاملStructural basis of the chiral selectivity of Pseudomonas cepacia lipase.
To investigate the enantioselectivity of Pseudomonas cepacia lipase, inhibition studies were performed with Sc- and Rc-(Rp,Sp)-1,2-dialkylcarbamoylglycero-3-O-p-nitrophenyl alkylphosphonates of different alkyl chain lengths. P. cepacia lipase was most rapidly inactivated by Rc-(Rp,Sp)-1,2-dioctylcarbamoylglycero-3-O-p-nitrophenyl octylphosphonate (Rc-trioctyl) with an inactivation half-time of ...
متن کاملCovalent immobilization of Pseudomonas cepacia lipase on semiconducting materials
Lipase from Pseudomonas cepacia was covalently immobilized on crystalline silicon, porous silicon and silicon nitride surfaces. The various stages of immobilization were characterized using FTIR (Fourier transform infrared) spectroscopy. The surface topography of the enzyme immobilized surfaces was investigated using scanning electron microscopy (SEM). The quantity of the immobilized active enz...
متن کاملPseudomonas cepacia lipase--mediated transesterification reactions of hydrocinnamates.
Use of lipase from Pseudomonas cepacia in transesterifcation reactions of ethyl hydrocinnamate with different alcohols has been examined. Among the alcohols tested, viz., n-butanol, iso-amyl alcohol, benzyl alcohol, n-octanol and 1-phenylethanol, only n-butanol yielded the transesterified product. Among the solvents tested, viz., n-heptane, n-hexane, cyclohexane, toluene, diisopropylether and n...
