摘要：The present study is the first report of the conversion of two simple polycyclic aromatic hydrocarbons, biphenyl and naphthalene, into the aliphatic polymer poly-β-hydroxybutyrate by a single bacterium. The bacterium we have identified as Sphingobium scionense sp. WP01T (=DSM 19371 T=ICMP 13533T) was originally isolated from contaminated soil containing oil residues and Pinus radiata sap and sawdust. We have shown that Sphingobium scionense sp. WP01T is able to accumulate poly-β-hydroxybutyrate from naphthalene and biphenyl when these are provided as sole carbon sources under nitrogen limited conditions. The generation of PHA from aromatic hydrocarbons as a feedstock provides a route for converting waste polluting hydrocarbons into useable biological polyesters. © 2011 IEEE.
