Abstract

1. 0.02 M glucose sterilised by filtration delays nitrification in mixed cultures. 2. Filtered glucose is not toxic to nitrifying bacteria, so the delay is presumably caused by the rapid growth of non-nitrifying bacteria. 3. 0.02 M glucose autoclaved in the medium stops nitrification, and is toxic to the nitrifying bacteria.
