The preservation buffers lead to “sneaker contigs”. A Abundance of spiked phages (Phi X174, c2, and T4). B Abundances of representative contigs are annotated at different taxonomy levels, the selected contigs are the contigs that have high abundance in the buffers other than SM buffer. C Genomic maps of the open reading frames (ORFs) which are predicted by prodigal and then annotated by blast to the NCBI protein database; the best hits were used for the annotation. Different colors indicate different annotated proteins, directional boxes indicate ORFs in the respective orientation. NA: not assigned, HTP: hypothetical protein
