Nutrient Broth can be used for the cultivation and enumeration of bacteria which are not particularly fastidious. streaks. NUTRIENT BROTH media a general purpose medium used for cultivating a wide variety of microorganisms. UNDERSTANDING BACTERIA MORPHOLOGY USING GRAM STAIN TECHNIQUE. An example of a commonly used resuscitation culture media is the tryptic soya agar. The fermentation media can also be differential but mostly it These are fluid selective media which incorporate substances that inhibit the growth of organisms other than those for which the medium was devised; for example, Selenite F inhibits coliform bacilli, whilst allowing the typhoid—paratyphoid organisms to grow freely as an enriched culture. This is a liquid medium which allows the microorganisms to multiply and has the essential nutrients that are required for it. Difference Between Broth and Stock. Tryptone Glucose Extract Broth with TTC A non-selective medium used to detect total heterotrophic microorganisms in water and other liquids. i use not to understand this types of culture even after attending lectures but through this short and easy to understand notes am able to explain to someone.

For example if we want to isolate a specific bacteria let’s say that can with stand an acidic environment from a sample of pond water and get rid of others, a selective media with a low pH will be taken which will allow the growth of only those organisms that can withstand acidity and will kill the others that cannot. Luria broth (LB broth), also called lysogeny broth or Luria-Bertani broth, is among the most common media for broth cultures.
