Studies on Oxygen Consumption in the Obligate Chemolithoautotroph Halothiobacillus neapolitanus Ramu Kakumanu*, John Latham, Neela .G, Suneel Chhatre & Newton P. Hilliard, Department of Physical Sciences, Eastern New Mexico University, Portales, NM 88130 Sulfur oxidation pathways Background Halothiobacillus neapolitanus is an aerobic, gram- negative, obligate chemolithoautotroph, which oxidizes reduced sulfur compounds such as sulfide, thiosulfate, sulfur, tetrathionate for energy, furthermore it has optimal growth at 30-400C and can proliferate at pH 4.5. To utilize H.neapolitanus, in ongoing enzymatic research and proteins thereof for commercial use it is necessary to elucidate its metabolic pathway, substrate to oxygen ratios and end products of substrate oxidation. Inorganic sulfur compounds are oxidized by two major pathways. These are identified as the PSO pathway that occurs in organisms such as Paracoccus versutus and P. dentrificans
