摘要：

The transformation of pyridine and several hydroxypyridines was investigated under different physiological conditions. Pyridine and 2-, 3- and 4-hydroxypyridine were metabolized aerobically within 9 days in a mineral salt medium inoculated with 10% sewage sludge. Under anaerobic conditions in the presence of nitrate or sulfate, pyridine and 3-hydroxypyridine were metabolized after a lag period of 2 months, while no transformation of 2- or 4-hydroxypyridine was detected. Experiments with C-14-labeled-pyridine showed that under denitrifying as well as under sulfate-reducing conditions pyridine was oxidized to carbon dioxide. Disappearance of nitrate and sulfate under anaerobic conditions was 79% and 85%, respectively, of the amount predicted from the stoichiometric equation for the complete transformation of pyridine.
