• Bacteria can replicate approximately every 20 minutes by binary fission.
• Binary fission is the form of cell division used by prokaryotes to reproduce.
• Cell division is the process by which cells duplicate.
• The level of replication will depend on the availability of nutrients and other suitable conditions such as temperature.
• There are many ways to culture bacteria, and these include: nutrient broth solution, colonies on an agar plate, and agar plates.
• Nutrient broth solution or culture medium, allows a liquid or gel to provide all the nutrients needed for bacteria to grow successfully.
• Agar plates are used to culture (grow) bacteria and fungi in the lab.
• Colonies are a visible cluster of microorganisms of the specific bacterium.
• Uncontaminated cultures are grown deliberately by humans or grown, other contaminating bacteria would compete for nutrients in the broth or agar.
• Some bacteria could be harmful (such as pathogens) and would complicate the results of experiments when testing the efficiency of antibiotics or other anti-microbial compounds.
