Why heterotrops prefer complex media?
Complex media are preferable for routine cultivation of microorganisms than chemically defined media because it provides highly enriched sources such as plant or animal extracts, vitamins, minerals, protein, sugar, and or blood to the organism, supplying them specific nutritional substances needed for their growth. Chemically defined media on the other hand does not supply such a vast abundance of nutritional substances.

What is enrichment media in microbiology?
Enriched media is different from Enrichment media... Enriched media: Blood and other special nutrients may be added to general purpose media to encourage the growth of fastidious microbes. These specially forfited media are called as enriched media. e.g. Blood agar, Chocolate agar. Enrichment media: This is a media which promotes the growth of a particular organism by providing it with the essential nutrients and rarely contains certain inhibitory substance to prevent the growth of normal competitors. e.g. Selenite F broth- this media favours thegrowth of Salmonella also prevents the growth of normal competitors like E. coli . but E.Coli do not perish in the medium but they do not flourish like Salmonella

Why are semisolid media sometimes preferred over techniques for evaluating bacterial motility?
