摘要：

Tributyl phosphate (TBP) is widely used in nuclear fuel processing and other waste generating chemical industries. Although TBP is bacteriostatic, some microbes are resistant to it and may degrade it. Under dark aerobiosis, purple non-sulfur photosynthetic bacteria degraded up to 0.6 mM TBP, initially present at 2 mM, within 3 weeks and under photosynthetic conditions, Rhodopseudomonas palustris degraded 1.6 mM TBP within 3 weeks. The curing of the Rhodopseudomonas palustris endogenous plasmid demonstrated that the genes involved in the TBP degradation are chromosomal.
