Abstract
The locations of hexachlorocyclohexane (HCH) catabolic (lin) genes were investigated in HCH degrading sphingomonad, Sphingobium indicum B90A (that was isolated from India). Southern blot analysis revealed the presence of linA1, linC, linDER and linX (linX1 and linX2) on the plasmid DNA in Sphingobium indicum B90A.
