  • Optimized lysis for tough samples – Isolate pure DNA from soil, stool, and other environmental samples
  • Inhibitor Removal Technology® - Eliminates 100% of humic substances and other PCR inhibitors, for DNA that is ready to use in downstream applications
  • Rapid protocol - Enables isolation of high quality, pure DNA from 250 mg samples in just 30 minutes


The PowerSoil® DNA Isolation Kit uses patented Inhibitor Removal Technology® to isolate microbial genomic DNA from all soil types and environmental samples, as well as fecal, stool and biosolid samples. The isolated DNA has the highest level of purity, enabling successful PCR and qPCR amplification of organisms from the sample. The kit is ideal for processing all environmental samples including difficult types containing a high humic acid content such as compost, sediment, and manure. PCR analysis has been performed to detect a variety of organisms including both Gram-positive and Gram-negative bacteria (e.g. Bacillus subtilis, Bacillus anthracis), fungi (e.g. yeasts, molds), algae, and actinomycetes (e.g. Streptomyces), and nematodes. The PowerSoil® DNA Isolation Kit distinguishes itself from other kits with a patented humic substance/brown color removal procedure that eliminates PCR inhibitors from even the most difficult soil types, enabling samples to be used for the most demanding downstream applications, including PCR, qPCR and next generation sequencing. 


“I used the kit to extract DNA from grape phylloxera in a soil sample that had high levels of composted material / humic acids. It worked very well compared to the Qiagen Stool kit and the final product from the extraction went through PCR without any problems. Thanks for making my life easier.”

The PowerSoil® DNA Isolation Kit is More Effective for Community Analysis by PCR 

  High Yield, Intact Genomic DNA

Total Genomic DNA was isolated from nine different sample types using the MO BIO PowerSoil® DNA Isolation Kit and soil DNA isolation kits from two other suppliers. All isolations were performed following the manufacturerís protocols. Eluted genomic DNA was displayed on a 0.8% TAE agarose gel (15 µl per lane).

PCR analysis using eubacterial primers was performed on 1 µl of the undiluted DNA elute. PCR products were displayed on a 0.8% TAE agarose gel. Lane M is DNA Marker.

Lane 1 - Landfill 0-3 inches       Lane 4 - Coffee Compost       Lane 7 - Mud Sediment
Lane 2 - Landfill 3-6 inches       Lane 5 - Marine Sediment       Lane 8 - Horse Manure
Lane 3 - Late-stage Compost       Lane 6 - Lake Sediment       Lane 9 - Mulch Topsoil

Only DNA isolated with PowerSoil® yielded a PCR product for Landfill samples (lanes 1 and 2), Lake Sediment (lane 6) and Mulch Topsoil (lane 9). DNA isolated using other supplier kits failed to amplify products for these samples, most likely due to high levels of humic acid substances remaining in the final DNA eluate.

Positive PCR amplification using PowerSoil® was observed with 100% of the samples. PCR analysis resulted in only 44% positive amplification with supplier kits tested.
