Microbiomics — the study of entire microbial genomes and their functions within an environment — is rapidly advancing from basic research into clinical translation and industrial application. From soil microbial ecology to the human gut microbiome, from environmental monitoring to disease diagnosis, microbiome research is reshaping multiple scientific disciplines.
109–1010 cells per gram
Each gram of soil hosts 109–1010 microbial cells — the most complex microbial habitat on Earth. Soil microbes drive carbon and nitrogen cycling, organic matter decomposition, and plant growth promotion, profoundly shaping global ecosystems. Soil samples are the richest source for studying environmental microbial diversity, soil health assessment, and agricultural optimization.
~100 trillion microbes
The human gut harbors approximately 100 trillion microbes with a gene pool roughly 150 times that of the human genome — often called the “second genome.” The gut microbiome is intimately linked to obesity, diabetes, cancer, and neurodegenerative diseases. Fecal samples serve as the primary window into gut microbiota research.
High-quality nucleic acid extraction is the foundation of microbiome research, yet soil and stool samples present extraction challenges far beyond those of routine specimens. These three barriers have long frustrated researchers:
Soil: Contains minerals, clay, plant debris, humic substances, and diverse microbial communities.
Stool: Contains bilirubin, bile salts, humic acids, plant-derived polysaccharides, and numerous soluble impurities.
These complex components make nucleic acid release and purification exceptionally difficult.
Humic acids, fulvic acids, and other humic substances share highly similar physicochemical properties with nucleic acids, readily co-precipitating during extraction. These compounds potently inhibit DNA polymerase activity, leading to PCR failure or severely degraded sequencing quality. Traditional extraction methods struggle to remove these inhibitors effectively.
Environmental microorganisms exhibit immense diversity in cell wall architecture: the thick peptidoglycan of Gram-positive bacteria, the chitin walls of fungi, and the extreme resistance of bacterial spores. A single lysis approach cannot achieve balanced disruption across all taxa, introducing significant community composition bias and incomplete coverage.
YALI BIOTECH leverages deep expertise across sample preservation, pre-treatment, nucleic acid extraction, and purification to offer a fully integrated product system for soil and stool nucleic acid extraction. Built on a “Preserve → Pre-Treat → Extract → Automate” workflow, it covers the entire journey from sampling to high-quality nucleic acids.

Soil and stool samples present three major challenges: (1) extremely complex composition including minerals, humic substances, bile salts, and polysaccharides; (2) severe PCR inhibitor interference from humic acids and fulvic acids that co-precipitate with nucleic acids; and (3) diverse microbial cell wall structures requiring different lysis strategies. YALI BIOTECH’s patented inhibitor removal technology and optimized lysis system address all three challenges, achieving A260/A230 ratios above 1.9.
YALI BIOTECH provides a complete workflow: sample preservation (YS21061 stool DNA preservation tube up to 2 years, YS21062 stool RNA preservation tube up to 7 days at room temperature), column-based extraction (YC22008-A optimized for NGS, YC22008-B optimized for PCR/qPCR), magnetic bead-based extraction (YM26011 flagship DNA kit with patented inhibitor removal, YMR91011 RNA kit), and the YALEPIC Pure 32 automated nucleic acid extraction platform (MC-A-32-16).
YALEPIC MagEVO stool & soil DNA extraction kit (YM26011) uses patented inhibitor removal technology with proprietary intellectual property formulations that selectively remove humic acids and fulvic acids. Combined with high-affinity silica magnetic beads achieving over 95% nucleic acid binding efficiency, the kit delivers A260/A230 ratios above 1.9 and meets the sensitivity requirements of ddPCR and low-input library preparation.
Yes. The YALEPIC MagEVO magnetic bead-based kits are automation-ready and work with the YALEPIC Pure 32 automated nucleic acid extractor as well as mainstream branded extraction instruments.
