Nocardia and Streptomyces are obligate aerobic saprophytes and are found in soil. As a group, the organisms may be differentiated by their action on substrates such as gelatin. N. brasiliensis forms abundant rounded colonies which adhere strongly to the wall of the tube or sink to the bottom in a mass. N. asteroides grows very poorly, developing flaky growth that is easily dispersed throughout the medium.Use Gelatin Broth 0.4% for differentiation of Nocardia and Streptomyces.
• Easy to read- Pattern of growth can be easily discerned on visual inspection.
• Ready to use– convenience of prepared media.
• Recommended for inclusion in the battery of substrates used to differentiate aerobic actinomycetes^3-5.
• Differential media-Nocardiabrasiliensisshows good growth with round, compact coloniesNocardia asteroidesexhibits no growth or very sparse, thin, flaky growthStreptomycesspecies show poor to good growth (stringy or flaky)In Gelatin Broth (0.4%), gelatin is the sole source of nitrogen and carbon. In this medium the ability of an organism to utilize gelatin as a protein source and decompose it into free amino acids is determined by its growth.
