Locality description
Parma, IT (contaminant: CEs)
1st BMT sampling in December 2017, 2nd in May 2018
Groundwater samples
Selected markers for BMT testing:
> Universal marker of 16S rDNA - U16SRT
> Organohalide respiring bacteria – bvcA and vcrA (VC reductases),
DHC-RT (Dehalococcoides mccartyi), Dsb (Desulfitobacterium sp.),
Dre (Dehalobacter sp.)
> Sulphate reducing b.– dsrA2 (dissimilatory sulphate reductase)
> Denitrifying bacteria – nirK (nitrite reductase)
> Nitrifying bacteria – AmoA (ammonium monooxygenase)
> HCH degrader – linA (γ-HCH dehydrochlorinase)
> BTEX degraders – DEF/G (catechol-2,3-dioxygenase), bssA (alpha
subunit of benzylsuccinate synthase gene)
