Semi-solid culture media are used to recover and grow microorganisms, especially those that are fastidious or have complex growth requirements, and to observe motility and other characteristics.

Semi-solid culture media examples: motility agar, thioglycollate medium, and semisolid agar.
Solid culture media examples: nutrient agar, blood agar, and chocolate agar.

Culture media in microbiology are composed of nutrients, pH buffers, and agar or gelatin, which provide the necessary environment for microbial growth.
