| Several bacteriological media are available for selectively detecting gram-negative bacteria in dairy products. Crystal violet tetrazolium agar (CVTA; Frank and Yousef, 2004), MacConkey agar (MAC; Difco, 1998), violet red bile agar (VRBA; Frank and Yousef, 2004), and 3M Coliform Petrifilm (CPETRI, 3M, St. Paul, MN) are examples of gram-negative selective media. Crystal violet tetrazolium agar, MAC, and VRBA contain crystal violet to inhibit the growth of grampositive bacteria, and MAC and VRBA also contain bile salts, which may inhibit some gram-negative organisms; therefore, CVTA is the recommended method for the detection of total gram-negative bacteria in milk (Frank and Yousef, 2004). Violet red bile agar and MAC also contain lactose and a pH indicator and can thus be used to differentiate non-lactose-fermenters from lactose fermenters, which include coliform bacteria. Coliform Petrifilm is designed to detect specifically coliform bacteria and is widely used in the dairy industry. |

抛砖引玉，试着翻译一下： 数个细菌培养基可选择性地用于检测奶制品中的革兰氏阴性细菌。革兰氏阴性选择培养基的例子有结晶紫四唑琼脂(CVTA;Frank and Yousef,2004)，麦康凯琼脂(MAC;Difco,1998)，结晶紫中性红胆盐琼脂(VRBA;Frank and Yousef,2004)和3M大肠菌纸片法(CPETRI、3M、St. Paul, MN)。研究发现，结晶紫四唑琼脂,MAC和VRBA含有的结晶紫会抑制革兰氏阳性菌的生长。另外，MAC和VRBA中均含有胆盐，而胆盐可能也会对某些革兰氏阴性细菌生长产生抑制。因而，有研究者推荐采用CVTA方法，该方法可用于检测奶制品中的总革兰氏阴性细菌(Frank and Yousef,2004)。结晶紫中性红胆盐琼脂和MAC均含有乳糖且可作为酸碱指示剂，因此可用于区分包括大肠杆菌在内的非乳糖发酵和乳糖发酵。此外，大肠杆菌纸片法旨在专门检测大肠杆菌细菌，在乳制品行业中得到广泛应用。 |
