Biology lesson. Students in a biology laboratory preparing microbial cultures. They are using bunsen burners to sterilise wire loops and use them to add microbes, such as bacteria and fungi, to petri dishes. The petri dishes contain growth mediums, which will be used to culture the microbes for further study. Photographed at the University of Newcastle, UK.
