In this video, we're going to briefly discuss chemically defined media. Chemically defined media is a specific type of microbial growth media that has an exact nutrient composition made of pure chemicals. Because it has an exact nutrient composition, the scientist is able to control the exact types and the exact concentrations of the molecules that are used to make the chemically defined media. Chemically defined media is used when a researcher wants to control the exact type and quantity of nutrients that are added to the media.
If we take a look at our image down below at the chemically defined media, notice that we have a set of very specific chemicals. The composition of chemically defined media is well-defined; it has an exact composition that is known. The exact molecules and the concentration of those molecules are known within the media that's being used, which is not always the case with other types of media. This is why chemically defined media can be really important to scientists.
This here concludes our brief introduction to chemically defined media and how it uses an exact nutrient composition that is known to the scientists. We'll be able to get some practice applying these concepts and learn more about different types of media as we move forward in our course. So, I'll see you all in our next video.
