NUTRIENT AGAR

Nutrient Agar media is the basic culture media used for maintaining microorganisms, cultivating fastidious organisms by enriching with serum or blood and are also used for purity checking prior to biochemical or serological testing.

Nutrient Agar is ideal for demonstration and teaching purposes where a more prolonged survival of cultures at ambient temperature is often required without risk of overgrowth that can occur with more nutritious substrate. It is one of the several non-selective media useful in routine cultivation of microorganisms. It can be used for the cultivation and enumeration of bacteria which are not particularly fastidious. Addition of different biological fluids such as horse or sheep blood, serum, egg yolk etc. makes it suitable for the cultivation of related fastidious organisms.

Nutrient Agar is a reliable, general purpose solid medium. It is an important medium in the field of microbiology. Its composition is uncomplicated yet efficient which makes it an essential medium in microbiology laboratories. Its composition supports the growth of a wide range of non-fastidious microorganisms. The medium composition includes peptone, beef extract, and agar. Peptone and beef extract are basic nutritional factors that provide nitrogen, carbon, vitamins, minerals to microorganisms, and agar plays an important role in solidification of agar. The solid surface provides a stable surface for microbial colonies to develop and also aids in observing and identification of morphology. It is the preferred medium for routine cultivation and to preserve microbial strains for education and research purposes. It is the trusted medium for viable bacteria counting, or for semi-quantitative measurement of microbial population in a sample. This quality of Nutrient Agar makes it valuable in ecological, food, and clinical microbiology where monitoring of bacterial quantity is important. Furthermore, it can also help in confirming purity of sample such as food sample. Its preparation procedure is also very simple just weigh, mic, autoclave, solidify, and use.

TM Media’s Nutrient Agar is a reliable medium for growing microorganisms, conducting purity tests, and educational use. It prevents overgrowth, extends culture viability, and can be enriched with blood or serum for demanding bacteria.
