NUTRIENT GELATIN 500 grams/bottle

Nutrient Gelatin is used to investigate the presence of proteolytic microorganisms, as evidenced by the liquefaction of gelatin, especially in the bacteriological analysis of water. The liquefaction rate is important in the characterization of Enterobacteriaceae family groups and other groups of microorganisms. For the plate count of organisms in water, this medium is replaced by solid media with agar. Nutrient Gelatin was one of the first solidifying agents used at the beginning of bacteriology and was originally used in the standard method for water and wastewater as a direct plate count technique, replacing the dilution method. As this method required incubation at approximately 20°C, it was not ideal for most organisms. Gelatin peptone and Beef extract provide nitrogen, vitamins, minerals and amino acids essential for growth.
