Fig. 5From: Uncovering a hidden diversity: optimized protocols for the extraction of dsDNA bacteriophages from soil16S rRNA gene contamination. 16S rRNA gene contamination in the five extracted and sequenced viromes. Viromes filtrated with a 0.22 μm filter and extracted with the optimized protocol have contamination levels < 0.02% (threshold for virome purity) [29] (a). Candidatus Saccharibacteria is the predominant contaminant of all viromes irrespective of the extraction method applied (b).Back to article page
