A pseudomonad was isolated from the fluoroacetate-producing plant Dichapetalum cymosum (Hook) Engl. and identified as Pseudomonas cepacia. We established that this isolate was capable of growing in fluoroacetate-enriched solutions without any reduction in growth rate. Our isolate of P. cepacia was capable of defluorinating 2.69 mg of fluoroacetate per 10(9) cells per h. Fluoroacetate was degrad...

Cephalosporins having a catechol through a variety of linkages to the C3 position and a different C7 side chain were prepared. Among them, 3-(catechol-4- ylcarbonyloxy)methylcephalosporin (14) and 3-[(E)-3-(catechol-4-ylcarbonyloxy)-1-propen-1-yl]cephalospo rin (10) showed excellent activity against Gram-negative activity including ceftazidime-resistant Escherichia coli, Pseudomonas aeruginosa,...

The comparative in vitro activity and synergy of cefepime were evaluated with clinical isolates of Pseudomonas aeruginosa and Pseudomonas cepacia from cystic fibrosis patients. The activity of cefepime, both alone and in combination, was comparable to those of other antibiotics. The clinical efficacy of cefepime in cystic fibrosis patients merits investigation.

Three kinds of lipases (from Candida antarctica, Pseudomonas cepacia, and Pseudomonas fluorescens) were encapsulated in inorganic matrices by the sol-gel method in order to synthesize chiral compounds by kinetic resolution. Sol-gel lipases prepared with vinyltriethoxysilane had higher hydrolysis activity for 2-octyl acetate than those with other silane precursors: tetramethoxysilane, methyltrim...

Infective endocarditis is rarely caused by Burkholderia cepacia. Pseudomonas putidahas not been reported to cause infective endocarditis so far. This is the first case of infective endocarditis being reported, that is caused by Pseudomonas putidaand Burkholderia cepaciain an immunocompetent host with no predisposing factors. Aortic valve replacement surgery was carried out and antibiotics were ...

An outbreak of subclinical mastitis in a flock of 620 milking sheep was investigated. Microbiological and epidemiological analyses identified the causative agent as belonging to the Burkholderia cepacia complex (formerly Pseudomonas cepacia). Every ewe in the milking flock was individually tested for subclinical mastitis on two separate occasions, 6 weeks apart, by the California (rapid) mastit...

Lipases have many applications in biotechnology, thanks to their ability of acylglycerides hydrolysis. They alsp possess the unique feature of acting at the lipid-water interface, which distinguishes them from esterases. Commercially useful lipases are produced by microorganisms with the extracellular lipase being produced by many bacteria including Pseudomonas. The greatest production of lipas...

Much of the morbidity and mortality in patients with cystic fibrosis (CF) is secondary to pulmonary infections with Pseudomonas aeruginosa and, more recently, with Pseudomonas cepacia. Prevention of colonization and subsequent infection would be a useful therapeutic strategy. The pili (fimbriae) of P. aeruginosa are a potential vaccine antigen, as they have been implicated in binding to respira...

The present research aims to study the process of immobilization lipase from Burkholderia cepacia by physical adsorption on graphene oxide derived (GO) grape seed biochar. Additionally, modified Hummers method was used obtain oxide. Moreover, Fourier transform infrared spectroscopy, Raman spectrum, X-ray diffraction, and point zero charge were for characterization GO. influences pH, temperature...
