| Popis: | A sequential anaerobic-aerobic biodegradation of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) was studied. The results demonstrated that: (i) a complete degradation of RDX was achieved within 20 days using a consortium of bacteria from a wastewater activated sludge, (ii) RDX degradation did not occur under aerobic conditions alone, (iii) RDX-degrading bacterial strain that was isolated from the activated sludge completely degraded RDX within 2 days, and (iv) RDX- induced protein expressions were observed in the RDX-degrading bacterial strain. Based on fatty acid composition and a confirmation with a 16S rRNA analysis, the RDX-degrading bacterial strain was identified as a Bacillus pumilus-GC subgroup B. |
