Anytime you perform a sequencing experiment you will get _some_ microbial/fungal contamination. Every time. You can even check this yourself today. Analyse any publicly available (unprocessed) whole genome sequencing data. Usually the contamination is <1% but it’s there.
This study hasn’t ruled out contamination as the cause for the results. Given that, it’s very likely to be BS.
