Fermenting Methane into Meat! The String Bio Story

Usually when you hear about meat's connection to methane, it's about all the methane that cows are emitting into the atmosphere, accelerating climate change. What if, however, you could capture methane before it goes into the atmosphere, and feed it to microbes which in turn convert it into protein-packed ingredients to make alt-meat?

Sounds like magic, but it's not magic, it's science! And it's a science that Dr. Ezhil Subbian and her team at String Bio are advancing right now.

The India-based company in 2022 closed its $20 million Series B round and is now scaling up to commercialize its microbial protein ingredients.

In this interview, Dr. Subbian and I talk about how she started the company, why she moved it from Silicon Valley to Bangalore, India, where they get the methane to feed their microbes, and much more.

It's a fun conversation with someone passionate about fermentation and seeking to scale it in a part of the world where it's desperately needed—where meat demand is rising the fastest: Asia.

So enjoy this conversation with a real pioneer in the microbial fermentation space as she tells you her story of going from biotech researcher to startup CEO.
