I'm not sure why you are leaving out the fact that they also used Serratia marcescens, which is considered pathogenic[1]. As for the other bacteria, what they used was not the "common soil bacteria" Bacillus subtilis, but Bacillus atrophaeus[2] which was known as Bacillus globigii at the time. I think this is the only clear factual mistake I can find in the article. The article also claimed that Bacillus globigii is now considered a pathogen, but I can't find much information about it outside of the referenced book. I'll leave it to someone else to weigh in on this one. [1]: https://en.wikipedia.org/wiki/Serratia_marcescens#Pathogenicity https://en.wikipedia.org/wiki/Serratia_marcescens#Pathogenic...
