Thanks for the nice comments! We think most of these microbes are halotolerant so don't require salt to survive but can withstand it--they don't seem to be strict halophiles at least, but we'll need to confirm that with further research and tests. We're not sure if the majority of the microbes in the salted beef made it past cooking depending on how long they boiled their food, so it's not even certain whether or not they would have made it to the gut at all to be honest. The samples that would be the most interesting to note for these is would be those that were not boiled--the wine, beer, water, ship biscuit! We'll write a post on that as soon as we find out more :)

Great idea! I am a fan of Patrick O'Brien and it would be amazing to see this work incorporated into historical fiction. Thanks!
