A bit of sleuthing from the company’s website to Wikipedia to Google Patents brought me to this: <a href="https://patents.google.com/patent/WO2021084159A1/en" rel="nofollow noreferrer">https://patents.google.com/patent/WO2021084159A1/en</a><p>It is not peas. It is a specific bacteria. They just talk about a microorganism on the website, probably because people don’t want to think about eating bacteria (though they eat yogurt just fine).
