Product Description
The ZymoBIOMICS™ DNA Miniprep Kit is designed for purifying DNA
from a wide array of sample inputs (e.g. feces, soil, water, biofilms, etc.),
that is immediately ready for microbiome or metagenome analyses. The
ZymoBIOMICS™ innovative lysis system eliminates bias associated with
unequal lysis efficiencies
1
of different organisms (e.g. Gram-
negative/positive bacteria including endospores
2
, fungi, protozoans,
algae, etc.), making it ideal for microbial community profiling. Unbiased
mechanical lysis of tough microbes is achieved by bead beating with the
innovative ultra-high density BashingBeads™ and validated using the
ZymoBIOMICS™ Microbial Community Standard
3
, as shown in Figure 3.
In addition, the ZymoBIOMICS™ DNA Miniprep Kit is equipped with Zymo
Research’s proprietary OneStep™ PCR Inhibitor Removal technology
enabling PCR from the most PCR prohibitive environmental samples rich
in humic and fulvic acids, tannins, melanin, and other polyphenolic
compounds. Coupling state-of-the-art lysis technology with Zymo-Spin™
Technology results in superior yields of ultra-pure DNA ideal for all
downstream applications including PCR, arrays, 16S rRNA gene
sequencing, and shotgun sequencing

Ultra-pure DNA from Inhibitor Rich Samples
Figure 1. The ZymoBIOMICS™ DNA Miniprep Kit provides inhibitor-free DNA even when challenged
with extremely inhibitor rich samples. Real-time PCR was used to evaluate eluates recovered using the
ZymoBIOMICS™ DNA Miniprep Kit, and kits from Suppliers Q
1
, P, and Q
2
. Reaction volumes consisted
of either 10% or 35% of the eluate from each kit to detect the presence of PCR inhibitors. Each reaction
contained 25 ng of Brettanomyces DNA. Delayed and/or no amplification indicates PCR inhibition from
inefficient inhibitor removal.
Superior Yields
Figure 2. The ZymoBIOMICS™ DNA Miniprep Kit provides superior yields when compared to Suppliers
Q

Validated with the ZymoBIOMICS™ Microbial Community Standard
B) Bias Free Microbial DNA Extraction Using ZymoBIOMICS™ DNA Miniprep Kit
From Human Stool
Figure 3. A) The ZymoBIOMICS™ DNA Miniprep Kit provides unbiased representation of the
organisms extracted from the ZymoBIOMICS™ Microbial Community Standard. DNA was extracted
from ZymoBIOMICS™ Microbial Community Standard using four different DNA extraction methods
(ZymoBIOMICS™ DNA Miniprep Kit, Human Microbiome Project Protocol, Supplier Q
1
, and Supplier Q
2
)
and analyzed using 16S rRNA gene sequencing. 16S rRNA genes were amplified with primers targeting
v3-4 region and the amplicons were sequenced on Illumina
®
MiSeq™ (2 x 250 bp). Overlapping paired-
end reads were assembled into complete amplicon sequences. The composition profile was determined
based on sequence counts after mapping amplicon sequences to the known 16S rRNA genes of the eight
different bacterial species.
B) The ZymoBIOMICS™ DNA Miniprep Kit reliably isolates DNA from even the toughest to lyse
Gram positive organisms, enabling unbiased analyses of microbial community compositions.
There is a significant increase in yield and Gram-positive bacterial abundance when DNA was isolated
using the ZymoBIOMICS™ DNA Miniprep Kit. Correlated with the results in Figure 3A, it can be concluded
that unbiased DNA isolation was achieved. DNA was extracted from 200 µl of human feces suspended in
PBS (10 % m/v) using four different DNA extraction methods (ZymoBIOMICS™ DNA Miniprep Kit, Human
Microbiome Project Protocol, Supplier Q
1
, and Supplier Q
2
) and analyzed using 16S rRNA gene
sequencing. 16S rRNA genes were amplified with primers targeting v3-4 region and the amplicons were
sequenced on Illumina
®
MiSeq™ (2 x 250 bp). Overlapping paired-end reads were assembled into
complete amplicon sequences. Amplicon sequences were profiled with Qiime using Greengenes 16S
rRNA gene database (gg_13_8).

Sample Collection
For high quality reproducible microbiomics data, DNA/RNA Shield™ is
recommended for sample collection to avoid bias or erroneous results due
to compositional changes from nucleic acid degradation or microbial
growth. DNA/RNA Shield™ provides an unbiased molecular snapshot of
the sample at the time of collection by preserving nucleic acids at ambient
temperature and inactivating organisms including infectious agents.
Samples can be stored and transported easily and safely with DNA/RNA
Shield™ and is ideal for applications such as PCR, 16S rRNA gene
sequencing, and shotgun metagenomic sequencing. DNA/RNA Shield™
can preserve nucleic acids in nearly any sample including feces, soil,
saliva, blood, and tissues.

™
Microbial
Community Standards
The ZymoBIOMICS
™
Microbial Community Standard (Cat. No. D6300)
is a mock microbial community of defined and well characterized
composition making it the perfect control for all microbiome profiling and
metagenomics analyses.
It is ideal for assessing bias of DNA extraction methods since it contains
three easy-to-lyse Gram-negative bacteria (e.g. Escherichia coli), five
tough-to-lyse Gram-positive bacteria (e.g. Listeria monocytogenes), and
two tough-to-lyse yeasts (e.g. Saccharomyces cerevisiae).
Bead Beating Device Calibration Protocol:
Zymo Research suggests calibrating bead beating devices with the
ZymoBIOMICS
™
Microbial Community Standard in order to ensure bias
free microbial extraction. For lysis on the Vortex Genie
, we suggest a
time course ranging from 10-45 minutes with the vortex at maximum
speed. For high-speed cell disruptors such as the MP FastPrep
-24 we
suggest a time course at maximum speed with a range of 3-10 minutes.
The resulting DNA should be evaluated by quantifying DNA yield and
changes in microbial profile at each time point. The bead beating time that
yields a profile that closely matches the theoretical composition should
become standard operating procedure for the bead beating device.
ZymoBIOMICS
™
Microbial Community DNA Standard (Cat. No.
D6305) is a mixture of genomic DNA extracted from pure cultures of eight
bacterial and two fungal strains. Genomic DNA from each culture was
quantified before mixing. The ZymoBIOMICS
™
Microbial Community
Standard allows for assessment of bias from library preparation,
sequencing, and bioinformatics analysis.
It serves perfectly as a microbial standard for benchmarking the
performance of microbiomics or metagenomics analyses, including those
provided by a 3
rd
party.

Figure 8. Characterization of the microbial composition of the two ZymoBIOMICS
™
standards with
shotgun metagenomic sequencing (left panel) and 16S rRNA gene targeted sequencing (right panel).
The measured composition of the two standards agrees with the theoretical/designed composition.
“DNA Standard” represents ZymoBIOMICS
™
Microbial Community DNA Standard (DNA version) and
“Microbial Standard” represents ZymoBIOMICS
™
Microbial Community Standard (cellular version).
Genomic DNA composition by shotgun sequencing was calculated based on counting the amounts
of raw reads mapped to each genome. 16S composition by 16S rRNA gene targeted sequencing
was calculated based on counting the amount of 16S raw reads mapped to each genomes.

A) Use ZymoBIOMICS
™
Microbial Standards for assessing GC-Bias in
Shotgun Metagenomics
B) Perfect for tracking PCR Chimera in 16S rRNA Gene Sequencing
Figure 9.
A) Library preparation for shotgun metagenomic sequencing was performed in two different ways: one
by supplier I and one by an in-house method. Shotgun sequencing was performed on Illumina
®
MiSeq
™
with paired-end sequencing (2 x 150 bp). Raw reads were mapped to the 10 microbial
genomes to evaluate the potential effect of GC content on sequencing coverage. Normalized
coverage was calculated by normalization by the average sequencing coverage of each genome.
B) PCR chimera increases with PCR cycle number in the library preparation process of 16S rRNA gene
targeted sequencing. 20 ng ZymoBIOMICS
™
Microbial Community Standard was used a template.
The PCR reaction was performed with ZymoBIOMICS
™
PCR Premix and with primers that target v3-
4 region of 16S rRNA gene. Chimera rate in percentage was determined with Uchime and using the
16S rRNA gene of the 8 bacterial strains in the standard as reference PCR.

Problem
Possible Causes and Suggested Solutions
Background
Contamination
• Clean workspace, centrifuge, and pipettes with 10%
bleach to routinely to avoid contamination.
• Use of kit in exposed environment without proper
filtration. Check pipettes, pipette tips, microcentrifuge
tubes, workspace, etc. for contamination.
• Make sure bags of columns and buffer bottles are
properly sealed for storage. Use of these outside a clean
room or hood can result in contamination.
Low DNA
Yield
Lysis Methods
• Refer to Appendix D for validated bead beating devices
and parameters.
• Bead beating devices that oscillate in a single dimension
(only vertically or only horizontally) have been observed
to inefficiently lyse very recalcitrant species. Devices that
oscillate three-dimensionally or in a figure-8 motion often
lyse microbes efficiently.
Incomplete Debris Removal
• For high density samples, ensure lysate is centrifuged
properly to pellet insoluble debris following bead beating.
Ensure that none of the debris is transferred to the Zymo-
Spin™ III-F Filter in the next step.
21
Low DNA Yield
(cont.)
Input
• If the lysate does not pass through the column or is
extremely viscous, use less input material. Too much
sample input can cause cellular debris to overload the
column and insufficient flow.
• Consult the Sample Input Table on Page 6 for
information on your particular input limit based on
sample.
Binding Step
• Ensure that the ZymoBIOMICS™ DNA Binding Buffer
is completely mixed with lysate before loading onto the
column. Improperly mixed samples can lead to poor
DNA recovery.
Elution Procedure
• Ensure the ZymoBIOMICS™ DNase/RNase Free Water
hydrates the matrix for at least 1 minute before
centrifugation.
• To increase yields, heat the ZymoBIOMICS™
DNase/RNase Free Water to 60ºC before use.
Additionally, users can reload the eluate onto the column
matrix, incubate at room temperature for 3 minutes, and
centrifuge again to increase yield without further dilution.
