Abstract

Sphingobium chinhatense strain IP26T is a conducive hexachlorocyclohexane (HCH) degrader isolated from a heavily contaminated (450 mg HCH/g soil) HCH dumpsite. IP26T degrades α-, β-, γ-, and δ-HCH, which are highly persistent in the environment. Here we report the draft genome sequence (~5.8 Mbp) of this strain.

Highlights

  • Sphingobium chinhatense strain IP26T is a conducive hexachlorocyclohexane (HCH) degrader isolated from a heavily contaminated (450 mg HCH/g soil) HCH dumpsite

  • In order to study the evolution of hexachlorocyclohexane (HCH)-degrading phenotypes at intragenus level among sphingomonads, we have isolated several HCH-degrading and/or -tolerating genotypes, including Sphingobium chinhatense strain IP26T from the HCH dumpsite [1] located at Chinhat, Lucknow (26°54= N and 81°09= E), India

  • Gas-liquid chromatographybased HCH isomer degradation analysis revealed that IP26T is a faster degrader of HCH isomers than the prototype bacterium Sphingobium indicum strain B90AT [2]

Introduction

Sphingobium chinhatense strain IP26T is a conducive hexachlorocyclohexane (HCH) degrader isolated from a heavily contaminated (450 mg HCH/g soil) HCH dumpsite. In order to study the evolution of hexachlorocyclohexane (HCH)-degrading phenotypes at intragenus level among sphingomonads, we have isolated several HCH-degrading and/or -tolerating genotypes, including Sphingobium chinhatense strain IP26T from the HCH dumpsite [1] located at Chinhat, Lucknow (26°54= N and 81°09= E), India. Gas-liquid chromatographybased HCH isomer degradation analysis (time dependent) revealed that IP26T is a faster degrader of HCH isomers than the prototype bacterium Sphingobium indicum strain B90AT [2].
