Innovative nitrogen biological fixation methods for maize
Discover novel bacteria that fix nitrogen without nif genes, offering a groundbreaking approach to enhance maize growth. Seeking partners for commercialization and expansion to other crops.
Overview
This groundbreaking research introduces novel bacteria capable of fixing atmospheric nitrogen without the traditional nitrogenase (nif) genes. These bacteria have been isolated and tested in maize, showing nitrogen fixation rates between 30-82%. This innovative approach challenges existing paradigms and offers significant potential for enhancing crop growth by providing a sustainable nitrogen source.
Technical specifications
The research has identified multiple strains of bacteria that fix nitrogen without releasing ammonia, urea, or nitrous oxide, thus providing an environmentally friendly alternative. The organisms are Generally Recognized As Safe (GRAS), making them suitable for food-grade applications. The study has involved four field experiments over several years, creating a library of over 1,400 strains. These strains thrive alongside other bacterial strains that also lack nif genes, indicating potential for use as novel inoculants in various crops.
Technology readiness level
The technology is currently at TRL 4, having been validated in controlled field experiments. Efforts are underway to partner with commercial entities for larger field trials and commercial scale-up. The research team is actively seeking sponsored research and partnerships to further develop and commercialize these strains.
