Using bacteria to give nutrients to crops rather than fertilizers, Maria Esperanza Martinez-Romero is making big steps toward creating sustainable farming practices. Her discoveries on nitrogen fixation in plants by bacteria is currently being implemented in Mexico and Peru. Known for her innovative work with bacteria, Maria has been instrumental in uncovering the complex relationships between microbes and their environments. Tune in to learn how bacteria might just be the key to solving some of our biggest environmental challenges, plus the parallels between plant bacteria and our own gut bacteria in episode twelve of The Inventing HerStory Podcast!
