| abundance and diversity of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (hmx)-metabolizing bacteria in uxo-contaminated marine sediments. | octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (hmx) is a toxic explosive known to be resistant to biodegradation. in this study, we found that sediment collected from two unexploded ordnance (uxo) disposal sites (uxo-3, uxo-5) and one nearby reference site (midref) in hawaii contained anaerobic bacteria capable of removing hmx. two groups of hmx-removing bacteria were found in uxo-5: group i contained aerotolerant anaerobes and microaerophiles, and group ii contained facultative anaerobes. in ... | 2007 | 17381523 |
