Fastidious organisms have complex nutrient requirements that may not be fully met by a chemically defined medium, which contains a limited set of known nutrients. These organisms may need additional growth factors or specific conditions that are present in more complex, undefined media. The lack of essential nutrients or factors in a chemically defined medium can result in poor growth or failure to grow at all for fastidious organisms.
The most fastidious organism likely grew poorly in the chemically defined medium because it requires specific nutrients, growth factors, or environmental conditions that are not provided in such media. Chemically defined media contain only known quantities of inorganic salts and simple organic compounds, lacking the complex mixtures of nutrients found in rich media. This deficiency can inhibit the growth of organisms that have specialized nutritional needs. Additionally, fastidious organisms often depend on the presence of specific metabolites or symbiotic relationships that may not be replicated in a chemically defined environment.
Chemically defined media is a type of growth medium in microbiology containing known quantities of specific chemical components. This allows for precise control over the nutrients available to the microorganisms being cultured, facilitating reproducibility and predictability in experiments. It does not contain complex organic materials such as yeast extract or peptones.
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

Defined medium.
synthetic
A chemically defined media is a media in which the chemical nature of all the ingredients and their amounts are known. These media are also called synthetic media, mainly chemoorganotrophic heterotrophs also can be grown in defined media with glucose as a carbon source and an ammonium salt as a nitrogen source.
simply agar medium

It's complex because the constituent elements of the medium (enzymatic digests of casein and soybean) are present in an undefined amount, and an amount which will vary from batch to batch. Contrast this to a chemically defined medium which will always contain the exact amount of constituent.
A medium
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.
Tryptone broth is considered a complex growth medium, as it is composed of a mixture of partially digested proteins such as tryptone, making it a nutrient-rich medium that supports the growth of a wide range of microorganisms.
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.
