A culture media is a special medium used in microbiological laboratories to grow different kinds of microorganisms. From a normative point of view, I discuss the extent to which cultural diversity should be promoted, firstly from the consumers' point of view, and secondly with consideration of cultural diversity that includes also diversity of identities. CULTURE MEDIA & CULTURE METHODS Culture Media: A liquid or gelatinous substance containing nutrients in which microorganisms, cells, or tissues are cultivated for scientific purposes. In comparison with defined media, which are good for growing picky bacteria, complex media can be thought of as a crowd-pleaser, suitable for growing many different types of less fastidious microbes. endobj But the world did need another kind of introductory text in mass communication, and that is how Understanding Media and Culture: An Introduction to Mass Communication was birthed.
