Media Preparation
Media Preparation is a fundamental laboratory process in biotechnology where specialized solutions (called growth media) are made to grow cells, bacteria, or other microorganisms. Think of it like creating the perfect food and environment that living cells need to grow. This is similar to how a chef prepares specific recipes, but in this case, it's for growing living things in a lab. The process requires careful measurement, mixing of ingredients, and ensuring everything is completely sterile (free from contamination). This skill is essential in many areas including pharmaceutical research, food testing, and medical laboratories.
