Costein's LDS Test Medium, 500G

Costein's LDS Test medium is recommended for identification of members of Enterobacteriaceae on the basis of lysine decarboxylase (LDC) and hydrogen sulphide (H2S) production. LDC-negative and H2S negative organisms show yellow colored growth e.g. Citrobacter, Proteus vulgaris, Proteus mirabilis, Providentia, Enterobacter, Shigella. LDC-positive and H2S positive organisms give black color and may be surrounded by a violet zone e.g. Salmonella, Edwardsiella and others. LDC-positive and H2S negative organism are violet in color e.g. Escherichia, Klebsiella, Hafnia, Serratia and some rare Salmonella and others. Application: Recommended for Identification of Members of Enterobacteriaceae on the Basis of Lysine Decarboxylase and Hydrogen Sulphide Production.
