From: Monitoring the microbiome for food safety and quality using deep shotgun sequencing

Heatmap (log10-scale) of HPP microbial composition and relative abundance (RPM) where absence (RPM < 0.1) is indicated in gray. Genera are ordered by summed abundance across samples. Samples were received from Supplier A (blue) and Supplier B (green). Red stars indicate matrix-contaminated samples (from Supplier A).
