Detection and biodegradation of explosives |
| abstract |
The present invention relates to an enzyme catalyzing the removal of nitrite from pentaerythritol tetranitrate (PETN), the enzyme PETN reductase. Azenzyme was produced by culturing a new strain of Enterobacter cloacae isolated from nature. The strain designated PB2 was deposited under NCIMB-40 718. The amino acid sequence of the enzyme and the gene encoding the enzyme (onr gene) have also been determined. The invention thus relates to an isolated pentaerythritol tetranitrate reductase (PETN reductase) enzyme which catalyzes the removal of nitrite from pentaerythritol tetranitrate (PETN) and a derivative thereof, as well as a gene encoding the enzyme. The invention further relates to processes for the large-scale production of PETN reductase enzyme and its use in biological recovery. In addition, the present invention provides a method for detecting the presence of PETN in a sample and a biosensor useful in such a method. Thus, the present invention is suitable for the preparation of a large batch of the enzyme according to the invention and for the purification of the environment contaminated with PETN and related compounds. The present invention is suitable for the detection of small amounts of PETN. ŕ |
