This article addresses the degradation of the polyamine spermine (Spm) by a strain of Bacillus subtilis used in the fermentation of soybeans to produce the Japanese fermented foodstuff “natto”. The authors have paraphrased half a sentence from a review of mine that dramatically misrepresents the whole sentence and meaning. In their article, the authors state, “However, it is widely accepted that bacteria do not produce Spm (Michael, 2016) and direct degradation of Spm by B. subtilis (natto) is unproven.” In fact, my review stated, “It had been accepted dogma that bacteria do not produce spermine (77); however, that supposition was incorrect, and in fact Spm has been detected in diverse bacteria (25).” (Michael, A.J. (2016) Polyamines in Eukaryotes, Bacteria and Archaea. J. Biol. Chem. 291, 14896-903 PMID: 27268252). In an age of fake news, this could be construed as fake citation.
