Nitrogen Fixation by Marine Agar-degrading Bacteria

Novel marine carbazole-degrading bacteria.

Eleven carbazole (CAR)-degrading bacterial strains were isolated from seawater collected off the coast of Japan using two different media. Seven isolates were shown to be most closely related to the genera Erythrobacter, Hyphomonas, Sphingosinicella, Caulobacter, and Lysobacter. Meanwhile, strains OC3, OC6S, OC9, and OC11S showed low similarity to known bacteria, the closest relative being Kord...

Obligate oil-degrading marine bacteria.

Over the past few years, a new and ecophysiologically unusual group of marine hydrocarbon-degrading bacteria - the obligate hydrocarbonoclastic bacteria (OHCB) - has been recognized and shown to play a significant role in the biological removal of petroleum hydrocarbons from polluted marine waters. The introduction of oil or oil constituents into seawater leads to successive blooms of a relativ...

Atmospheric Nitrogen Fixation by Methane-oxidizing Bacteria.

Davis, J. B. (Socony Mobil Oil Co., Inc., Dallas, Tex.), V. F. Coty, and J. P. Stanley. Atmospheric nitrogen fixation by methane-oxidizing bacteria. J. Bacteriol. 88:468-472. 1964.-Methane-oxidizing bacteria capable of fixing atmospheric nitrogen were isolated from garden soil, pond mud, oil field soil, and soil exposed to natural gas, indicating a rather wide prevalence in nature. This may exp...

Nitrogen fixation by reductively dechlorinating bacteria.

Significant advances in the ecology, physiology and genetics of reductively dechlorinating bacteria have revealed their important environmental roles in bioremediation and in the global chlorine cycle. N2 fixation has been widely observed in symbiotic, associative and free-living bacteria. Here we show physiological and molecular evidence that reductively dechlorinating bacteria are capable of ...
