Mobilization, cloning, and sequence determination of a plasmid-encoded polygalacturonase from a phytopathogenic Burkholderia (Pseudomonas) cepacia.
Phytopathogenic strains of Burkholderia cepacia (synonym Pseudomonas cepacia) produce endopolygalacturonase, whereas strains of clinical and soil origin do not. Growth of a phytopathogenic strain (ATCC25416) at elevated temperatures resulted in nonpectolytic derivatives that were either cured of a resident plasmid or contained a plasmid of reduced mass. The resident 200-kb plasmid (pPEC320) in ...
متن کاملCytotoxicity associated with trichloroethylene oxidation in Burkholderia cepacia G4.
The effects of trichloroethylene (TCE) oxidation on toluene 2-monooxygenase activity, general respiratory activity, and cell culturability were examined in the toluene-oxidizing bacterium Burkholderia cepacia G4. Nonspecific damage outpaced inactivation of toluene 2-monooxygenase in B. cepacia G4 cells. Cells that had degraded approximately 0.5 micromol of TCE (mg of cells(-1)) lost 95% of thei...
متن کاملMutants of Pseudomonas cepacia G4 defective in catabolism of aromatic compounds and trichloroethylene.
Pseudomonas cepacia G4 possesses a novel pathway of toluene catabolism that is shown to be responsible for the degradation of trichloroethylene (TCE). This pathway involves conversion of toluene via o-cresol to 3-methylcatechol. In order to determine the enzyme of toluene degradation that is responsible for TCE degradation, chemically induced mutants, blocked in the toluene ortho-monooxygenase ...
متن کاملStructure of the O9 antigen from Burkholderia (Pseudomonas) cepacia.
The O9 antigen of Burkholderia (Pseudomonas) cepacia has the following disaccharide repeating-unit: -->4)-alpha-D-Glcp-(1-->3)-alpha-L-Rhap-(1--> The same unit is present in the O antigens of Serratia marcescens strain S1254 and serogroup O4 (predominantly acetylated at O-2 of rhamnose in the latter case).
متن کاملInterspecies biofilms of Pseudomonas aeruginosa and Burkholderia cepacia.
The leading cause of morbidity and mortality in cystic fibrosis (CF) continues to be lung infections with Pseudomonas aeruginosa biofilms. Co-colonization of the lungs with P aeruginosa and Burkholderia cepacia can result in more severe pulmonary disease than P. aeruginosa alone. The interactions between P. aeruginosa biofilms and B. cepacia are not yet understood; one possible association bein...
