Comments "The genetic complexity or genome size of microbial community genomes can be assessed by re-association of community DNA. Such broad-scale analysis has revealed [primary sources] that the community genome size equals the size of 6,000–10,000 Escherichia coli genomes in unperturbed organic soils, and 350–1,500 genomes in arable or heavymetal-polluted soils. These values may be conservative, as genomes representing rare and unrecovered microorganisms are probably not included in the analysis."
