Monomethylhydrazine (MMH), along with hydrazine and 1,1-dimethylhydrazine are the main components of hydrazine fuels. Information on the fate of MMH in soil and its overall effect on soil microbial activity is not known, though MMH is known to be toxic to a number of soil bacteria. Despite the fact that axenic bacterial cultures are inhibited by the three hydrazines, Ou and Street reported that soil respiration, and total bacterial and fungal populations in soil, were not inhibited by hydrazine at concentrations of 100 ..mu..g/g and lower. Even at 500 ..mu..g/g, only total bacterial populations in soil were inhibited by the presence of hydrazine. They also reported that hydrazine rapidly disappeared in soil. The authors initiated this study to investigate the effect of MMH on soil microbial activity and on degradation of the chemical in soil.
