Some of us like hills and others are fond of beaches. Microbes are no different! Some love fresh air and so stay outside, the more shy ones feel comfier inside, some don’t mind any location as long as their favourite pals are with them and others don’t thrive close to their enemies. This affinity of different microbes for different positions and locations can be seen in any environment they choose to inhabit—be it the human gut, soil aggregates or waste.
