| Abstract: | Exponentially growing cultures ofNitrosomonas europaea were inhibited by addition of 0.5  g nitrapyrin ml–1. This inhibition was increased by simultaneous addition of 0.046 g Cu2+ ml–1 as copper sulfate. This contradicts a previous report that copper relieves inhibition of ammonia oxidation by nitrapyrin, which report has formed the basis for hypotheses regarding the mechanism of action of this inhibitor. |
