Average DNA yield obtained using the four commercial DNA extraction kits1.

DNA extraction kit1

DNA yield (mg DNA/g dry wt feces)3


52.4 ± 14.5b


57.0 ± 22.6b


151.3 ± 47.1a


187.2 ± 69.4a

The following extractions accounted for various fecal specimen weights (10, 25, 50, 100, and 200 mg) and DNA yield was normalized by percent fecal dry matter (26%, 35%, and 41%)2.

1M, Mobio Ultra Clean® Fecal DNA Isolation Kit; Q, QIAamp® DNA Stool Mini Kit; FSp, FastDNA® SPIN Kit; FSo, FastDNA® SPIN Kit for Soil

2Values of DNA yield were based on n = 45/DNA extraction method and were normalized based on the dry weight of the respective fecal sample

3Treatment groups with different letters indicate significant differences between groups (P < 0.05). Values are means ± SE.
