1.1.5 Culturing Microorganisms
In this lesson, you will learn how microorganisms are cultured in the laboratory. You will explore how bacteria reproduce by binary fission and how they are grown in nutrient broth or on agar plates. You will also examine aseptic techniques used to prevent contamination and ensure safe practice in school laboratories, and practise calculating the cross-sectional area of bacterial colonies and estimating bacterial population growth using standard form.
