We named them according to preconceptions as to what would grow there (possibly not good scientific practice!). Let’s call the first site our BAD soil sample site, a dry site with some fine gravel […]

In this module, we will culture microbe colonies from our soil samples in order to determine what is living in our soil. In biology, a colony refers to several individual organisms of the same species living closely together, usually for mutual benefit. A bacterial colony (or colony of other microorganisms) is a cluster of organisms […]
