Yes I think it could be. About 60% of the sample seems to be rRNA. So it partly depends if it’s cheaper to put the additional cost in the prep or the sequencing.
For a proof of concept I would tend to put it on the sequencing then better characterize the whole process, before deciding how to proceed.
I'm curious, working with environmental (soil, water etc) samples I encountered samples whose content was even over 90% rRNA. In the swabs, is most of the rRNA you encountered is human? and if so do you think incorporating a human rRNA depletion to the prep would be easier then a e.g. general use case sort of pull-down probe?
Interesting and educational read!
Do you think rRNA depletion could be incorporated somehow?

Thank you for the answer Nava!

Yes, mostly human it seems this paper provides some numbers: https://www.medrxiv.org/content/10.1101/2022.05.12.22274799v1.full-text
