Culture media contains the nutrients needed to sustain a microbe. Culture media can vary in many ingredients allowing the media to select for or against microbes. Glucose or glycerol are often used as carbon sources, and ammonium salts or nitrates as inorganic nitrogen sources in culture media. Composition of culture media: Bacteria infecting humans (commensals or pathogens) are chemoorganoheterotrophs. When culturing bacteria, it is very important to provide similar environmental and nutritional conditions that exist in its natural Size: 64KB. media, (2) Enriched media, (3) Selective media, (4) Indicator media, (5) Transport media, and (6) Storage media. 1. BASAL MEDIA. Basal media are those that may be used for growth (culture) of bacteria that do not need enrichment of the media. Examples: Nutrient broth, nutrient agar and peptone water. Staphylococcus and Enterobacteriaceae grow. Bacteriological Culture. Media. Dr. Mejbah Uddin Ahmed Several Terms Media: The nutrient material in which bacteria grow. Culture: A bacterial growth in media. Broth: A liquid medium. Agar plate: Round culture dish with semi-solid nutrient l Terms Slant: Tube with semi-solid media, with a slanted surface. Colony: A circular area of limited bacterial growth.

zdescribe the preparation and storage of Culture media When culturing bacteria, it is very important to provide similar environmental and nutritional conditions that exist in its natural habitat. Most culture medium contains water, a source of carbon & energy, source of nitrogen.   Bacterial Culture Media: classification, types and uses J Acharya Tankeshwar Bacteriology, Culture Media used in Microbiology, Laboratory Diagnosis of Bacterial Disease 37 Culture media contains nutrients and physical growth parameters necessary for . To explain the term endotoxin in terms of its chemical composition and location in bacterial cells INTRODUCTION TO BACTERIOLOGY 1. Two main threads in the history of bacteriology: 1) the natural history of bacteria and 2) the Reisolate the bacteria in pure culture from the experimental infection. These rules cannot be applied to all. Media that inhibit the growth of unwanted microorganisms and support the growth of the organism of interest by supplying nutrients and reducing competition are called selective example of a selective medium is MacConkey contains bile salts and crystal violet, which interfere with the growth of many gram-positive bacteria and favor the growth of gram-negative bacteria.

Media lacking an amino acid such as proline in conjunction with E. coli unable to synthesize it were commonly used by geneticists before the emergence of genomics to map bacterial chromosomes. Selective growth media are also used in cell culture to ensure the survival or proliferation of cells with certain properties, such as antibiotic. An easily prepared and readily reproducible culture medium for general use is described. A wide range of standard media can be prepared from it by simple modifications. We should like to thank Mr P. D. Laverack and Mr D. Garwes for their exellent technical assistance, and Marmite Ltd. for much useful information about their product. A growth medium or culture medium is a solid, liquid or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation, or small plants like the moss Physcomitrella patens. Different types of media are used for growing different types of cells. The two major types of growth media are those used for cell culture, which use specific. Bacteriological Media: Bacterial media can be classified into 3 classes. 1. Solid media or nutrient agar media. 2. Liquid or broth media. 3. Semisolid media. Application & Classification: Bacteriological media can be sub-divided into the following categories depending on their application. (a) Cultivation media (b) Storage media (c) Enrichment.
