Shared Bacterial Phyla in the Rhizosphere and Gut: The Soil-Gut Link

Explore the soil-gut connection: researchers are uncovering shared bacterial phyla rhizosphere gut across soil around plant roots and the human digestive tract. The rhizosphere—the zone of soil around plant roots—hosts diverse microbial communities that influence nutrient availability, plant health, and ecosystem resilience. In humans, the gut microbiome likewise depends on a few broad bacterial phyla that perform essential functions. Common players include Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes, and you can find these phyla recurring in both environments. The existence of shared bacterial phyla rhizosphere gut hints at a universal microbial toolkit that operates across soil and in the gut, shaping how we metabolize nutrients, modulate immunity, and respond to stress. This cross-kingdom link prompts new thinking about health, farming, and ecology, linking soil stewardship to human well-being. As researchers trace these overlaps, the health implications become tangible. Diet shapes the gut microbiome just as soil and plant ecosystems shape the rhizosphere: plant-based foods feed gut microbes, while rhizosphere microbes influence crop health and nutrient availability for the human diet. Recognizing the shared phyla rhizosphere gut guide helps scientists design prebiotics and probiotics that support overlapping metabolic functions. InnerBuddies provides a white-label Gut Health Operating System that lets brands and clinics tailor insights to their customers. The platform’s Gut Microbiome Health Index, developed under an exclusive IP collaboration with EAFIT University in Colombia, offers a 0–100 score of gut wellness. InnerBuddies also offers personalized probiotics and prebiotics advice tailored to your objectives and your microbiome. Learn more about how this index is calculated on the InnerBuddies product page. But the health story extends beyond individuals. Farming practices that nurture a robust rhizosphere—cover crops, composting, reduced tillage, and diverse rotations—often yield produce with richer, more beneficial microbial communities that support human nutrient intake and immune function. The shared bacterial phyla rhizosphere gut concept reinforces the idea that soil health and gut health are two sides of the same ecological coin. InnerBuddies' modular platform supports this perspective by cataloging bacteria abundances, linking functional pathways as positive or negative, and offering target-group analyses for Healthy Aging, Endurance Sport, Skin & Hair Health, and more. This integrated view helps brands communicate how sustainable agriculture can translate into healthier diets and better well-being. Whether you’re a consumer exploring gut health or a business building a white-labeled testing product, InnerBuddies has options to fit your needs. See how personalized nutrition advice is generated by comparing three-day food diaries with stool samples, leveraging its large database of how foods affect the gut microbiome. You can start with the consumer-ready route by visiting the InnerBuddies product page, or subscribe to ongoing insights with the InnerBuddies subscription. For companies ready to scale, the InnerBuddies B2B program offers a white-label, modular platform to power your own gut-health testing products.
