S. mutans is bile solutibility test
WebThe specificity of the bile solubility test remains high, and it is the most accurate single test for the identification of S. pneumoniae [3]. The bile solubility phenotype is due to the activation of the major autolytic enzyme (an N-acetylmuramyl-l-alanine amidase encoded by the lytA gene), which can also be achieved by sodium deoxycholate.
