| 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. |

拋磚引玉,試著翻譯一下: 數(shù)個(gè)細(xì)菌培養(yǎng)基可選擇性地用于檢測(cè)奶制品中的革蘭氏陰性細(xì)菌。革蘭氏陰性選擇培養(yǎng)基的例子有結(jié)晶紫四唑瓊脂(CVTA;Frank and Yousef,2004),麥康凱瓊脂(MAC;Difco,1998),結(jié)晶紫中性紅膽鹽瓊脂(VRBA;Frank and Yousef,2004)和3M大腸菌紙片法(CPETRI、3M、St. Paul, MN)。研究發(fā)現(xiàn),結(jié)晶紫四唑瓊脂,MAC和VRBA含有的結(jié)晶紫會(huì)抑制革蘭氏陽(yáng)性菌的生長(zhǎng)。另外,MAC和VRBA中均含有膽鹽,而膽鹽可能也會(huì)對(duì)某些革蘭氏陰性細(xì)菌生長(zhǎng)產(chǎn)生抑制。因而,有研究者推薦采用CVTA方法,該方法可用于檢測(cè)奶制品中的總革蘭氏陰性細(xì)菌(Frank and Yousef,2004)。結(jié)晶紫中性紅膽鹽瓊脂和MAC均含有乳糖且可作為酸堿指示劑,因此可用于區(qū)分包括大腸桿菌在內(nèi)的非乳糖發(fā)酵和乳糖發(fā)酵。此外,大腸桿菌紙片法旨在專(zhuān)門(mén)檢測(cè)大腸桿菌細(xì)菌,在乳制品行業(yè)中得到廣泛應(yīng)用。 |
