What agar media is ideal to selectively grow enterococci?


I am doing a project and i need to extract microbes from sand and grow just the enterococci. Is there an agar media that selectively grows enterococci?

I would also need to selectively grow e.coli and coliforms, but i found that Coliform Chromo select agar should do the job for both of them on the same plate.

  1. Ecoli flourishes close to plant roots, can debase youthful produce crops.
    Coliform ChromoSelect Agar is a chromogenic blend that contains two chromogenic substrates, Salmon-GAL and X-glucuronide. Coliforms produce a catalyst called β-D-galactosidase, which cuts Salmon-GAL, bringing about the salmon-to-red shading of coliform states. The protein β-D-glucuronidase delivered by Escherichia coli cleaves X-glucuronide. Escherichia coli forms dull blue-to-violet hued states because of cleavage of both Salmon-GAL and X-glucuronide.The expansion of tryptophan improves the indole response, accordingly expanding discovery dependability in mix with the two chromogens. To confirm Escherichia coli, add a drop of Kovac′s reagent on the dim blue-to-violet province. The arrangement of cherry-red tone shows a positive response.
    Coliform ChromoSelect Agar is a specific chromogenic medium suggested for concurrent discovery of Escherichia coli and all out coliforms in water and food tests
