Class-level composition of the domain Bacteria and Archaea based on rRNA (raw reads) among the four individual metagenomes and the subtractive bacterial community associated to the PA metagenomes. For the subtraction, we used prokaryotic rRNA sequences that were found to be unique (i.e., meaning they exhibited >95% identity for over 90 bp to any sequence in the FL metagenomes) to the PA fraction. Free-living (FL); Particulate-associated (PA).
