Abstract

Although enzymes catalyzing the reduction of nitrate to nitrite have been studied in a variety of organisms, very few of them have been suffiently [sic] purified to permit detailed characterization. The nitrate reductase enzymes of C. sputorum ssp. bubulus and C. fetus ssp. fetus have been partially purified in the present research. One basic premise of this research was that the nitrate reductase activity of C. fetus ssp. fetus would be similar to that of C. sputorum ssp. bubulus. Some research has been done on the nitrate reduction abilities of C. sputorum ssp. bubulus (42,53,62,77). Within the genus Campylobacter only C. sputorum ssp. bubulus and C. fetus ssp. fetus are able to degrade nitrate under anaerobic conditions. The potential for similarity of the enzymes was thought to be great. The results of this research indicated that the nitrate reductase activity of the two different species of Campylobacter is indeed similar.
