Marker genes of microbiome typically sampled from residential and hospital indoor ventilation system.

Marker genes of microbiome sampled from the locations such as estuaries, wetland, and river bed.

Marker genes of microbiome in soil sampled from the locations such forest, glaciers, and permafrost.

Marker genes of microbiome typically sampled from sewage and sludge.

Marker genes of microbiome sampled from, for example, tap/drinking water, swimming pool, river, and ocean.
