Lysine iron agar or LIA is a differential media used to distinguish bacteria that are able to decarboxylate lysine and/or produce hydrogen sulfide from those that cannot.[1] This test is particularly useful for distinguishing different Gram-negative bacilli—especially among the Enterobacteriaceae.[1]
