The lysine iron agar slant or LIA slant test is used to distinguish bacteria which are able to decarboxylate lysine and/or produce hydrogen sulfide from those that cannot. This test is particularly useful for distinguishing different Gram-negative bacilli—especially among the Enterobacteriaceae. ==Procedure== The LIA slant is inoculated by stabbing the agar to within 1/4 inch of the butt of the tube and streaking the slant. The slant is then incubated at 35°C for 18–24 hours. The results are scored as follows: *purple slant/yellow butt = LSI Negative *turbid, purple butt = LSI Positive *black precipitate = H2S Positive 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Lysine iron agar slant」の詳細全文を読む スポンサード リンク
