The ZymoBIOMICS DNA/RNA Miniprep Kit is designed for purifying DNA and RNA from a wide array of sample inputs (e.g. feces, soil, plant, water, and biofilms) that is ready for microbiome or metagenome analyses. The ZymoBIOMICS innovative lysis system eliminates bias associated with unequal lysis efficiencies of different organisms (e.g. Gram-negative/positive bacteria, fungus, protozoans, and algae). The provided DNA/RNA Shield preserves nucleic acids at ambient temperatures, providing an unbiased molecular snapshot of the sample. The procedure uses Zymo-Spin Column technology that results in high-quality DNA and total RNA (including small RNAs 17-200 nt) that is free of PCR inhibitors (e.g. polyphenols, humic acids, and fulvic acids). Ready for RT-PCR, arrays, sequencing, etc.

DNA and RNA were coextracted from human and mouse stomach biopsy using the ZymoBIOMICS DNA/RNA kit for downstream 16S rRNA sequencing targeting the hypervariable region V4. Microbiota analysis revealed Firmicutes being more transcriptionally active than Bacteroidetes along with selective enrichment and depletion of specific bacteria in the stomach.

Researchers used 16s rRNA gene sequencing to identify the microbial community in a sulfur-rich, low-temperature environment and showed not only the presence of sulfur oxidizing microbes but also aerobic Flavobacterium. The DNA was extracted from mineral precipitate using ZymoBIOMICS DNA/RNA.

The ZymoBIOMICS DNA/RNA kit was used for co-extraction from 0.22 μm nitrocellulose water filters preserved in DNA/RNA Shield as well as biofilm membranes. Metagenomic and metatranscriptomic sequencing showed decreased microbial diversity and load after microfiltration and reverse osmosis. Water treatment also reduced the presence of antibiotic resistance genes and viruses.
