Termites are important insects for the environment because they break down organic materials and recycle nutrients. Despite their significance, little is known about the intricate link between termites and their gut microbiota. With an emphasis on nutrient cycle and decomposition processes, this study explores the symbiotic interactions between termites and the microorganisms that are connected with their gut. We discovered important microbial taxa involved in nitrogen fixation and lignocellulose breakdown by characterising the stomach microme of three termite species using a mix of genetic and culture-based approaches. Our findings show a complicated web of relationships between termites, their intestinal diet, and the health of the ecosystem. This study advances our knowledge of termite biology and has ramifications for the creation of innovative biotechnology uses.
