Microbial consortia are groups of diverse microorganisms that have the ability to act together in a community. Such consortia are common in nature and are known to play important roles in many ecosystems but are not always well understood. Soil management and nutrient mobilization are one area where complex communities of microbes are known to be important, whether it be a naturally occurring consortium, or a man-made consortium.  In this episode of Absolute Gene-ius Jordan and Cassie talk with Dr. Ray Ketchum form Agrinos about the microbial consortia he and his team cultivate and produce to improve plan health and increase crop yields. We learn about the challenges of fermenting mixtures of more than 20 diverse microorganisms to reproducibly make products that improve plant health and mobilize nutrients in a completely organic way. As you might expect, digital PCR plays in important role in Ray’s R&D and quality control process.  Here, they use dPCR to titer each of the species within their consortia for quality and regulatory purposes, a task that cannot be done by cell culture methods given the range of bacteria involved. Cassie’s career corner gets Ray sharing his full career development story from undergraduate, through grad school and postdoc positions, and into his professional career. Ray is generous in sharing his early misconceptions about miscalculations while providing advice to help other avoid similar missteps.  Visit the Absolute Gene-ius page to learn more about the guest, the hosts, and the Applied Biosystems QuantStudio Absolute Q Digital PCR System.
