    • The general method involves contacting a bacterial colony with a .beta.-D-galactosidase substrate and a carbon source metabolizable by a plurality of coliform species but not metabolizable by E. coli, and detecting reaction product signals of the substrate and carbon source. Typically, the carbon source is a carbohydrate, preferably adonitol, esculin, salicin, amygdalin, or cellobiose. The absence of both reaction product signals indicates the presence of non-coliform bacteria; the presence of both reaction product signals indicates the presence of non-E. coli coliform bacteria; and, the presence of the .beta.-D-galactosidase substrate reaction product signal and absence of the carbon source reaction product signal indicates the presence of E. coli.A signal may identify a reaction product itself (e.g. a colored product derived from a chromogenic form of the substrate or from a chromogenic reagent which interacts with the product, etc.), or an effect of a reaction product on or at the colony (e.g. catabolite repression, growth, localized pH change, etc.). Preferably, the .beta.-D-galactosidase substrate reaction product signal is provided directly by a .beta.-D-galactosidase reaction product and the carbon source reaction product signal is provided by carbon source reaction product-induced catabolite repression of the .beta.-D-galactosidase substrate reaction product signal at a portion of the colony.
    • 一般方法包括使细菌菌落与β-D-半乳糖苷酶底物和可由多种大肠菌群代谢但不能被大肠杆菌代谢的碳源接触,并检测底物和碳源的反应产物信号。 通常,碳源是碳水化合物,优选地是阿丹糖醇,七叶树素,水杨蛋白,杏仁苷或纤维二糖。 两个反应产物信号的不存在表明存在非大肠菌群; 两个反应产物信号的存在表明存在非E。 大肠杆菌; 并且β-D-半乳糖苷酶底物反应产物信号的存在和不存在碳源反应产物信号表明存在大肠杆菌。 信号可以鉴定反应产物本身(例如衍生自底物的显色形式的着色产物或与产物相互作用的显色试剂等),或反应产物在菌落上或在菌落上的作用(例如 分解代谢物阻抑,生长,局部pH变化等)。 优选地,β-D-半乳糖苷酶底物反应产物信号由β-D-半乳糖苷酶反应产物直接提供,碳源反应产物信号由碳源反应产物诱导的β-D-半乳糖苷酶底物的分解代谢物抑制 反应产物信号在菌落的一部分。

    • A method of compressing an integer multiplication table including the steps of first eliminating one of the two symmetrical and identical sections in the table, eliminating the products of 0 multiplier and 0 multiplicand, moving the product of the multiplier having an index of n into the location of index (n-1) for the multiplier, using one-half of the number of the largest multiplier as the largest multiplier index for the compressed multiplication table, moving into the non-continuous memory space of the compressed multiplication table by a page-filling method the product of the largest multiplier index value that is larger than the compressed multiplication table such that the multiplication table after compression can be stored on the same page.
    • 一种压缩整数乘法表的方法,包括以下步骤:首先消除表中两个对称和相同部分之一,消除0乘法器和0乘法器的乘积,将具有索引为n的乘法器的乘积移动到位置 (n-1),使用最大乘数的数目的一半作为压缩乘法表的最大乘数索引,通过页面转换到压缩乘法表的非连续存储器空间中, 填充方法是大于压缩乘数表的最大乘数指数值的乘积,使得压缩后的乘法表可以存储在同一页上。
