Method The analysis of total DNA content in the sediment was carried out by diphenylamine assays or HPLC measurements, accurately inter-calibrated (Dell'Anno et al. 1998 PMID 9726866). Researchers first estimated the extracellular DNA fraction by calculating the difference between total DNA and the DNA within living biomass, determined by synoptic determinations on virus, prokaryote, unicellular eukaryote (protozoan), and small metazoan (meiofauna) abundances. They then supported their findings as described in BNID 105855
