Ammonia-oxidizing bacteria along meadow-to-forest transects in the Oregon Cascade Mountains

Article Abstract:

Research has been conducted on NH (sub)3 -oxidizing bacteria in meadow-to-forest transects. The authors describe their study of NH (sub)3 -oxidizing bacteria community composition carried out by generating terminal restriction fragment length polymirphism fingerprints of NH (sub)3 monooxygenase subunit A gene amplified via PCR from soil DNA.

Naturally occurring bacteria similar to the methyl tert-butyl ether (MTBE)-degrading strain PM1 are present in MTBE-contaminated groundwater

Article Abstract:

Research has been conducted on methyl tert-butyl ether-contaminated groundwater. The authors report the discovery of bacterial strain discovered in this groundwater which is identical to the native strain PM1, degrading methyl tert-butyl ether, in its ribosomal 16S DNA sequence.
