大肠菌群是指一群能发酵乳糖、产酸、产气、需氧和兼性厌氧的革兰氏阴性无芽孢杆菌。多年来国内外都以大肠菌群作为食品污染的常用指示菌之.并评价和判断食品被粪便污染的程度和有无肠道致病菌污染的可能。目前已被国内外广泛应用于食品卫生工作中。在试验中经常会遇到一些书本上没有提到的实际问题,本文中对大肠菌群在检测过程中经常碰到的问题做了阐述。 Coliform is a group of gram-negative bacillus that ferment lactose, produce acid, gas, aerobes and facultative anaerobes. Over the years both at home and abroad to coliform bacteria as a common indicator of food contamination and evaluate and determine the extent of food contamination by fecal contamination and the possibility of contamination with enteric pathogens. Has been widely used in food hygiene at home and abroad. In the experiment often encounter some practical problems not mentioned in the book, this article on coliform bacteria in the testing process often encountered problems are described.
