5. Why are simple stains able to "stick” to bacteria? Explain the chemical properties of the stain and bacteria surface. 3-Preparation of Bacterial Smears and Simple Stains Introduction Microbial cultures are handled using aseptic technique. Aseptie technique is a set of procedures used to minimize contamination of materials by microorganisms from the environment, and to minimize the spread of cultures around the laboratory. In this experiment, you will be using an inoculating loop to transfer bacteria from a culture tube...
