Verified step by step guidance1
Understand the term 'fastidious organism': Fastidious organisms are those that have complex nutritional requirements and need specific nutrients to grow.
Identify the characteristics of different types of media: Differential media distinguishes between different types of organisms based on their biological characteristics. Selective media allows the growth of certain types of organisms while inhibiting others. Reducing media is used to grow anaerobic organisms by reducing oxygen levels.
Define 'Complex media': Complex media contains a variety of ingredients such as peptones, meat extracts, and yeast extracts, providing a rich supply of nutrients that can support the growth of fastidious organisms.
Analyze why complex media is suitable: Since fastidious organisms require specific nutrients, complex media, with its rich and varied nutrient content, is ideal for supporting their growth.
Conclude that complex media is the best choice for growing fastidious organisms due to its ability to provide the necessary nutrients that these organisms require.
