Evaluation of rapid and simple techniques for the enrichment of viruses prior to metagenomic virus discovery.

Highlights: [•] The effect of simple virus enrichment methods were tested on a metagenomics dataset. [•] Centrifugation, filtration or nuclease-treatment was evaluated. [•] A multi-step enrichment method increased the proportion of virus sequences. [•] This evaluation guides researchers in their choice of enrichment methodology. [ABSTRACT FROM AUTHOR]
