✦ Synopsis

The level of superoxide dismutase, catalase, and peroxidase was determined in obligately thermophilic bacteria after growth either in the presence of methyl viologen (paraquat) or exposed to a n increased atmospheric oxygen concentration. In general, the superoxide dismutase level in these organisms was not altered b y paraquat addition and had a varied response to oxygenation. Incorporation of paraquat in the growth medium resulted in minimally three-fold higher levels of catalase. The peroxidase level varied as a response t o oxygen stress whereas cellular catalase levels were generally higher.

The effect of different 0, concentrations on denitrification in freshwater sediment was studied using the acetylene blockage technique. Denitrification occurred over a wide range of 0, concentrations ranging from 10.1 t o 0.33 ymol ml-1 in nitrate amended sediment. However, denitrifying activity was
