Transcript text: General purpose media are characterized by allowing the growth of a broad range of microbes.
Solution
The answer is the first one: allowing the growth of a broad range of microbes.
Explanation for each option:
Allowing the growth of a broad range of microbes: This is correct. General purpose media are designed to support the growth of a wide variety of microorganisms. They provide the necessary nutrients and conditions for many different types of bacteria and fungi to grow, making them suitable for general cultivation purposes.
Being synthetic and chemically definable: This is incorrect. Synthetic and chemically definable media are specifically formulated with known quantities of all ingredients. General purpose media, on the other hand, are not necessarily chemically defined and often contain complex ingredients like peptones and yeast extract.
Containing only one nonsynthetic nutrient: This is incorrect. General purpose media typically contain a variety of nutrients, both synthetic and nonsynthetic, to support the growth of a broad range of microorganisms. They are not limited to just one nonsynthetic nutrient.
In summary, general purpose media are characterized by their ability to support the growth of a wide range of microbes.
