Thanks for your reply. Since I am working with bacterial RNA, splicing and introns aren't applicable. I agree with you though for eukaryotes, there can be many reads in introns in Ribo-Zero depleted RNA.

For example, is from a paper which did (among other things) a comparison between poly A-selected and rRNA-depleted libraries, and the main difference was the increased number of reads in introns.

However, since I am not working in a species with introns, I think it is more likely that contaminating genomic DNA is the problem. I am doing some tests with additional DNase treatments.
