Hydrogen and acetate inhibit the microbial degradation of propionate and ethanol in digesting sludge. Propionate oxidation is more sensitive than ethanol oxidation to product activities. This difference can be explained on thermodynamic gro...

The nitrite formed from nitrogen dioxide (NO2) was oxidized more readily in soil that had been treated previously with the gas than in soil not so pre-exposed. The reaction was inhibited by 1.0 but not by 0.01 mM chlorate. The population of...

Anabaena species are commonly colonized by bacteria, especially during N2-fixing blooms. Generally these associations do not represent bacterial attack on algal hosts. Instead, the algal N2-fixing capabilities are increased in the presence ...
