  •  Rapidly purifies DNA from microbial cultures in 20 minutes
  • Yields high quality and high molecular weight DNA is ready for PCR, restriction digests and other downstream applications
  • Isolates DNA from yeast, fungi, Gram-negative and Gram-positive bacteria
  • No hazardous organic solvents or enzymes required


The UltraClean® Microbial DNA Isolation kit is designed to isolate high quality genomic DNA from 1.8 ml of microbial culture. A variety of microorganisms including bacterial spores and fungal types have been tested successfully with this kit.

The principal of this kit is to lyse the microorganisms by a combination of heat, detergent, and mechanical force against specialized beads. The cells are lysed using our specially designed Vortex Adapter on a standard vortex. The released DNA is then bound to a silica spin filter, washed and the DNA is recovered in certified DNA-free Tris buffer. The UltraClean® Microbial DNA Isolation Kit requires our Vortex Adapter for maximum cell lysis efficiency.


Speed your protocol up to 20% in using our PowerVac™ Manifold Mini System!

Customer Comments

Easy, 30 minute purification of DNA from microbes

"Overall, the MoBio Laboratories UltraClean Microbial DNA isolation kit is quick, easy and affordable. It has found a method to overcome the lysing issues faced by researchers who work with gram positive and/or resistant organisms. I am pleased with this kit and would highly recommend it to others." the entire review at


New Method for Ectomycorrhizal Roots

The MO BIO UltraClean® Microbial DNA Kit works well for us. We have been trying to isolate DNA from ectomycorrhizal roots. Published methods for this are available, but they are slow and may involve highly toxic chemicals. When isolating DNA from pine ectomycorrhizas, we use the Microbial DNA Kit in conjunction with IRS (Inhibitor Removal Solution, available from MO BIO) and obtain PCR-ready DNA. No grinding or freezing is necessary. The process is simple and rapid.
