Abstract/OtherAbstract:
Penicillium corylophilum Dierckx, isolated from a contaminated water wet, double-base propellant, was able to completely degrade glyceryl trinitrate (GTN) in a buffered medium (pH 7.0) containing glucose and ammonium nitrate. In the presence of 12 mg of initial fungal inoculum, GTN (48.5 to 61.6 mumol) was quantitatively transformed in a stepwise process to glyceryl dinitrate (GDN) and glyceryl mononitrate (GMN) within 48 h followed by a decrease in the GDN content with a concomitant increase in the GMN level. GDN was totally transformed to GMN within 168 h, and the complete degradation of GMN was achieved within 336 h. The presence of glucose and ammonium nitrate in the growth medium was essential for completion of the degradation of GTN and its metabolites. Complete degradation of GTN by a fungal culture has not been previously reported in the literature.
