Studying the taxonomic relationship of oxygen metabolizing enzymes in aerobic bacteria relative to their 16S r-RNA(DNA) phylogenetic positioning, among the organisms comprising the family, Azotobacteraceae, Pseudomonadaceae and Bacillaceae. Specific interests include in surveying the oxygen metabolizing enzymes found in free-living nitrogen fixing bacteria; characterization of the nitrogen fixation reaction (via acetylene reduction) in Streptomyces species. Also of interest are the bioremediational aspects of Coastal Center Ground Water after the addition of known substrates like acetate, and the natural detection of endogenous acetate generated via acetogenesis. A related area is using specific 16S-rRNA (or16Sr-DNA) sequence segments as probes for the classification and identifying specific bacterial species.
