To overcome this limitation, DNA is often amplified with multiple displacement amplification (MDA), which causes an unavoidable bias. Here, we describe a DNA-spiking method to avoid the bias that is created when using amplification of DNA before metagenome sequencing. To obtain sufficient DNA for sequencing, a bacterial 16S rRNA gene was amplified and the obtained DNA was spiked to a DNA sample containing DNA from a bacteriophage population before sequencing using Ion Torrent technology. After sequencing, the 16S rRNA gene reads DNA was removed by mapping to the Silva database. The new DNA-spiking method was compared with the MDA technique.The new method provides a simple and inexpensive protocol with very low bias in sequencing of metagenomes for which low amounts of DNA are available.",
