2,4,5-Trichlorophenoxyacetic acid, more commonly known as 2,4,5-T, is a widely-used herbicide. For example, it is often used as a weed killer for home lawns. It is considered to be less readily biodegradable than the analogous herbicide 2,4-D. The greater resistance to microbial metabolism likely stems from the additional chlorine substituent on the aromatic ring. However, bacteria have been identified that are capable of metabolizing 2,4,5-T (
Daubaras et al., 1995).
