Thermo Scientific™ Tyrosine Agar

Description

Differentiate aerobic actinomycetes on the basis of tyrosine hydrolysis using Tyrosine Agar.

Differentiate aerobic actinomycetes on the basis of tyrosine hydrolysis using Thermo Scientific™ Remel™ Tyrosine Agar. Mishra et al. developed a taxonomic scheme for aerobic actinomycetes on the basis of biochemical characteristics¹. A simplified scheme for identification of most commonly isolated actinomycetes was developed by McGinnis et al. and includes tyrosine, xanthine, hypoxanthine, and casein tests². Upon extended incubation, Nocardia brasiliensis and Streptomyces spp. exhibit proteolytic activity on tyrosine agar.

The aerobic acinomycetes are a heterogeneous group of genera and include the species of Nocardia and Streptomycces³. As a group, the organisms are gram-positive, catalase positive, and may be presumptively identified by staining procedures, microscopic morphology, and substrate degradation.

• Ready to use – Convenience of a prepared media
• Easy to interpret – Clearing of tyrosine due to enzymatic hydrolysis around and/or under growth indicates a positive test. Growth without clearing of medium indicates a negative test.

This medium contains beef extract and peptone that provide carbohydrates, vitamins nitrogen compounds and salts essential for the growth of aerobic actinomycetes. Peptone also provides nutrients in the form of amino acids and peptides. This medium detects the presence of the hydrolytic enzyme that degrades tyrosine resulting in clearing of the media surrounding and beneath the areas of growth.
