Bacteria identification culture medium

阅读：2发布：2023-11-05

专利汇可以提供Bacteria identification culture medium专利检索，专利查询，专利分析的服务。并且A culture medium which provides an environment for positive and nontransient identification of proteus and providence strains of enteric bacteria utilizes a combination of L-tryptophane with ferric ammonium citrate and brom cresol purple with the optional addition of L-phenylalanine in a slightly acid medium. The culture is also provided with a gelling agent such as agar in order to produce a slant and with nutrients for the bacteria. The combination of components may be incorporated into otherwise known culture media as well. When the combination is incorporated into slightly acid screening media such as lysine iron agar, a positive test for proteus and providence bacteria can be effected. When incorporated in other screening media such as Kligler iron agar or triple sugar iron agar which are slightly alkaline, this combination of ingredients improves the screening ability of these culture media although it does not provide a positive test for proteus and providence bacteria.，下面是Bacteria identification culture medium专利的具体信息内容。
