On World Microbiome Day we celebrate all things microbial, all around the world. We introduce international microbiome researchers and microbiome‐literate professionals to the public to raise awareness of the vibrant and diverse world of microbes and we invite the public and industry professionals to share their thoughts and activities with the microbiome community. On 27 June each year, we all come together to share our passion and knowledge about microbiomes and their value to humanity and the planet.
