Wow, thank you for linking that article. When writing this post I was unsuccessful at finding the original article I mentioned.
The one you provided is extremely similar in nature and also mentions that oleic acid is great for growing the yeast. The big difference is that in the one you sent over sesame seed oil was also considered a good growth medium for the yeast. This seems to contradict what I originally read. Which might be related to the specific type of oil they use. Maybe the roasted sesame oil is bad for growing it or the other way around (not sure).
One thing to note is that I’ve been successfully using a moisturizing lotion which actually contains sesame seed oil. This sort of contradicts many things in these studies. So not really sure how that all works. My own theory is that if the oil is easy for the yeast to consume then it proliferates. However, if the skin (or the lotion) has certain components which make it hard for the yeast to feed off the oil, this allows the skin to use the oil to replenish itself as needed.
Hope that helps. Will update if I finally find that study I read (will check through my universities database).
Also look forward to hearing any updates.
