MODEL RELEASED. Bacterial culture. Masked technician examining a petri dish containing a bacterial culture using a platinum wire loop held in gloved hands. This petri dish has an agar nutrient medium on which bacteria are grown. Lines of bacteria can be seen growing on the dish where they were streaked. This involves running a wire loop that has been placed in contact with a bacterial culture over the agar. By heating the loop,each successive set of streaked lines leaves fewer bacteria,until round colonies form around single bacteria. This technique is used to isolate particular strains of bacteria,which may then be incubated and grown in pure form | |
