  A test medium and method for detecting, quantifying, identifying and differentiating up to four (4) separate biological materials in a test sample. A test medium is disclosed which allows quantifying and differentiating under ambient light aggregates of biological entities producing specific enzymes, which might include general coliforms, E. coli, Aeromonas, and Salmonella in a single test medium. A new class of nonchromogenic substrates is disclosed which produce a substantially black, non-diffusible precipitate. This precipitate is not subject to interference from other chromogenic substrates present in the test medium.; In one embodiment, the substrates are selected such that E. coli colonies present in the test medium show as substantially black, general coliforms colonies show in the test medium as a blue-violet color, Aeromonas colonies present in the test medium show as a generally red-pink color, and Salmonella colonies show as a generally teal-green color. Other microorganisms and color possibilities for detection and quantification thereof are also disclosed. An inhibitor and method for making a test medium incorporating the inhibitor are disclosed.

  一种检测介质和方法，用于检测、量化、识别和区分检测样本中多达四（4）种不同的生物材料。本发明公开了一种测试介质，可在环境光下对产生特定酶的生物实体聚集体进行定量和区分，这些生物实体可能包括单个测试介质中的普通大肠菌群、大肠杆菌、气单胞菌和沙门氏菌。公开了一类新的非变色基质，这种基质会产生一种黑色的、不可扩散的沉淀物。在一个实施方案中，基质的选择是这样的：存在于测试培养基中的大肠杆菌菌落显示为黑色，一般大肠菌群菌落显示为蓝紫色，存在于测试培养基中的气单胞菌菌落显示为粉红色，沙门氏菌菌落显示为茶绿色。此外，还公开了其他微生物及其检测和定量的颜色可能性。此外，还公开了一种抑制剂和制作含有该抑制剂的测试培养基的方法。
