Endo agar (also called Endo's medium) is a microbiological growth medium with a faint pink colour.〔(Mondofacto )〕 Originally developed for the isolation of ''Salmonella typhi'', it is now used mostly as a coliform medium. Most gram-negative organisms grow well in this medium, while growth of gram-positive organisms is inhibited.〔Becton, Dickinson and Company, (), 2006〕 Coliform organisms ferment the lactose in this medium, producing a green metallic sheen (i.e. ''Escherichia coli''), whereas non-lactose-fermenting organisms produce clear, colourless colonies,〔 i.e. ''Salmonella'' sp.. ==Typical composition== Endo agar typically contains (w/v):〔EMD Chemicals, (), 2002〕 *1.0 % peptone *0.25 % dipotassium hydrogen phosphate (K2HPO4) *1.0 % lactose *0.33 % anhydrous sodium sulfite (Na2SO3) *0.03 % fuchsine *1.25 % agar 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「Endo agar」の詳細全文を読む スポンサード リンク
