What do Microbes do?

Did you know that scientists still don’t know what many of the microbes in our gut do? Scientists from the UK, USA, Australia and Italy have collaborated to use a technique called “metagenomics” to collate a huge database on human gut bacteria from 31 countries. It includes >4600 different species – 70% of these had never been grown in the lab before, and 40% lack functional knowledge.
