The gene of NAD`-dependent formate dehydrogenase (FDH) from Mycobacterium vaccae N10 was cloned into Escherichia coli by hybridization with digoxigenin-labeled DNA probes, which were prepared by amplification of the chromosomal DNA from the bacterium by the polymerase chain reaction with degenerate primers. The primers were designed on the basis of the most conserved parts of known sequences of...
T-helper (Th)2 cytokines play a central role in asthma. Therefore, a double-blind randomised study was conducted to investigate whether heat-killed Mycobacterium vaccae (SRL172), a potent downregulator of Th2 cytokines, can reduce allergen-induced airway responses in patients with atopic asthma. A total 24 male asthmatics participated in this study. A bronchial allergen challenge was performed ...
Chloroform (CF) degradation by a butane-grown enrichment culture, CF8, was compared to that by butane-grown Pseudomonas butanovora and Mycobacterium vaccae JOB5 and to that by a known CF degrader, Methylosinus trichosporium OB3b. All three butane-grown bacteria were able to degrade CF at rates comparable to that of M. trichosporium. CF degradation by all four bacteria required O(inf2). Butane i...
The initial reactions in the cometabolic oxidation of the gasoline oxygenate, methyl tert-butyl ether (MTBE), by Mycobacterium vaccae JOB5 have been characterized. Two products, tert-butyl formate (TBF) and tert-butyl alcohol (TBA), rapidly accumulated extracellularly when propane-grown cells were incubated with MTBE. Lower rates of TBF and TBA production from MTBE were also observed with cells...
