Ashdown's medium, a selective medium containing gentamicin, may be required for cultures taken from nonsterile sites . " Burkholderia cepacia " medium may be a useful alternative selective medium in nonendemic areas, where Ashdown's is not available.

Second, the isolate is cultured on mannitol salt agar, which is a selective medium with 7 9 % NaCl that allows " S . aureus " to grow, producing yellow-colored colonies as a result of mannitol fermentation and subsequent drop in the medium's pH.

Upon transformation of the purified prey library with the bait plasmid, positive selection is achieved by growing the host E . coli on minimal medium lacking histidine ( NM selective medium ) that is usually supplemented with varying concentrations of 3-amino-triazole ( 3-AT ), a competitive inhibitor of HIS3.

:I'm not sure how anyone could possibly answer the question as put; the quantity of medium you need would depend on the number of samples you're going to test, and on the lab protocol you're using for the testing ( I also wonder why you're using trypticase soy agar vs MacConkey medium-unless you're making your own selective medium, in which case again quantity depends on the recipe you're using .-Nunh-huh 02 : 44, 5 March 2008 ( UTC)
