Structure and conservation of a polyethylene glycol-degradative operon in sphingomonads.
Sphingopyxis terrae, and Sphingopyxis macrogoltabida strains 103 and 203, can degrade polyethylene glycols (PEGs). They differ in the following respects: (i) different substrate specificities (chain length) of assimilable PEG, (ii) PEG-inducible or constitutive PEG-degradative proteins, and (iii) symbiotic or axenic degradation of PEG. S. terrae was able to incorporate PEG 6000, but strain 103 ...
متن کاملCharacterization of diverse 2,4-dichlorophenoxyacetic acid-degradative plasmids isolated from soil by complementation.
The diversity of 2,4-dichlorophenoxyacetic acid (2,4-D)-degradative plasmids in the microbial community of an agricultural soil was examined by complementation. This technique involved mixing a suitable Alcaligenes eutrophus (Rifr) recipient strain with the indigenous microbial populations extracted from soil. After incubation of this mixture, Rifr recipient strains which grow with 2,4-D as the...
متن کاملTransfer and expression of degradative and antibiotic resistance plasmids in acidophilic bacteria.
The genetic accessibility of selected acidophilic bacteria was investigated to evaluate their applicability to degrading pollutants in acidic environments. The IncP1 antibiotic resistance plasmids RP4 and pVK101 and the phenol degradation-encoding plasmid pPGH11 were transferred from neutrophilic bacteria into the extreme acidophilic eubacterium Acidiphilium cryptum at frequencies of 1.8 x 10(-...
متن کاملDetection and characterization of conjugative degradative plasmids in xenobiotic-degrading Sphingomonas strains.
A systematic survey for the presence of plasmids in 17 different xenobiotic-degrading Sphingomonas strains was performed. In almost all analyzed strains, two to five plasmids with sizes of about 50 to 500 kb were detected by using pulsed-field gel electrophoresis. A comparison of plasmid preparations untreated or treated with S1 nuclease suggested that, in general, Sphingomonas plasmids are cir...
متن کاملDegradative enzymes in osteoarthritis.
A central feature of the osteoarthritic disease process involves erosive destruction of the articular cartilage extracellular matrix (ECM) on the surfaces of diarthrotic joints. The resultant loss of joint function makes studies on mechanisms underlying ECM degradation critical for treatment of the disease and prevention of disability. Candidate pathways to account for the loss of cartilage inv...
