Thermo Scientific™ Lysozyme Broth

Description

• Differentiate aerobic actinomycetes like Nocardia and Streptomyces using Thermo Scientific™ Remel™ Lysozyme Broth
• A taxonomic scheme for identification of aerobic actinomycetes is developed based on biochemical characteristics which included testing for the growth in the presence of lysozyme 1
• The enzyme lysozyme breaks down the cell walls of certain aerobic actinomycetes such as Streptomyces spp
• and are referred sensitive and will not grow in lysozyme broth
• Lysozyme resistance is more reliable to differentiate Nocardia and Streptomyces 2
• The aerobic actinomycetes are a heterogenous group of genera and include species of Nocardia and Streptomyces 3
• As a group, the organisms are gram-positive, catalase-positive and may be presumptively identified by staining properties, microscopic morphology, and substrate degradation 4
• Lysozyme Broth contains lysozyme that inhibits the growth of some aerobic actinomycetes, but not all
• Most Nocardia spp
• are resistant and grow in the presence of lysozyme
• This medium contains beef extract, peptone, and glycerol that supply carbohydrates, vitamins, nitrogen compounds, salts, and amino acids necessary for the growth of aerobic actinomycetes.
