A sterile nutrient medium is important to prevent contamination by unwanted microorganisms that may interfere with the growth of the desired organism being cultured. Contaminants can alter the experimental results and compromise the purity of the culture.
Sterile environments such as medical-grade clean rooms or sterile laboratories are examples of settings where microbial contamination is controlled to the point that the medium may not contain viable microbes. However, outside of controlled sterile environments, it can be difficult to find a medium that is completely free of viable microbes.
Inoculation is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium.
They are grown on medium that contains the nutrient that they cannot synthesize
because it is important that in nutrient media to grow up only bacteria that may be present in your mouth.In tha case tha swabs are not sterile in nutrient media will growth mouth and swab bacteria and the will give a flas positive result.
Bacillus subtilis is grown on nutrient agar or in nutrient broth. The preferred medium is M9 with glucose.
The medium is a sterile substrate that takes the place of soil; it provides a place for the plants to grow in as well as a medium through which the nutrient solution can pass. Hydroponics employs a sterile medium, one that does not interact with the plants - perlite, vermiculite, inert stone or rock wool. Hydroponic gardening system that is based on water, not soil. So container is a hydroponic growing medium. There are various types of hydroponic growing mediums like Oasis Cube, Coconut Fiber, Fillers, Ebb and Flow System and aeroponics.

simply agar medium
Inoculation is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium.
Usually a sterile mix of vermiculite, pearlite, moss, and steralized soil.
Hydroponics substitute a nutrient medium in place of soil. for the plants to root and grow. The nutrient medium may be either a water solution or an inert material.
The agar will solidify and form a gel-like substance in the nutrient broth. This agar-nutrient mixture is used as a solid medium for growing and isolating bacteria in a laboratory setting.
Using sterile gloves and making sure it does not touch any non-sterile/contaminated objects
