One of the major challenges in microbiome science has been distinguishing what is a potential environmental contaminant from a true, bona fide microbiome signal. Challenges associated with metagenomic sequencing with low biomass environments include the distinction between a true signal versus contamination, a remnant DNA from a sampling kit or extraction kit or the environment.
