Our interest in this research was mainly to compare the physiological characteristics of microorganisms derived from subsurface and surface environments and their ability to transform heterocyclic aromatic chemicals. We selected essentially indole and pyridine compounds as representatives of heterocyclic compounds. The samples investigated originated from the subsurface drillings at the Savannah River Plant, from surface samples in Pennsylvania, from municipal sewage of State College, Pennsylvania, and from pyridine-contaminated sites at Indianapolis. At different physiological conditions (aerobic, denitrifying, sulfate-reducing or methanogenic), different groups of microorganisms are active. Not only the thermodynamics of microbial physiology vary, but different metabolic pathways are used by the various types of microbial processes. Therefore, it was important to determine under which physiological conditions a compound was metabolized, and to clarify the metabolic conditions under which intermediate(s) were produced. 29 refs.
