A device adapted for containing a volume of growth medium and employed for detection of gas produced by a microorganism or microorganisms putatively contained within a test sample and added to the growth medium, comprising a primary chamber, a dome defined by the top surface of the primary chamber and communicating therewith, the dome establishing a fluid level and adapted for collection of gas produced by a microorganism within the growth medium, and a fill section adjacent to and communicating with one end of the primary chamber, the fill section spaced apart from the dome and extending above the fluid level, and further defining an opening for the addition of a test sample is disclosed. The device may be sealed by means of a removable closure. An apparatus consisting of an array of substantially identical devices is also disclosed. In addition, methods of using the device and apparatus for detecting and estimating numbers of microorganisms, and for analyzing samples putatively containing a microorganism, are disclosed.
一种装置,适于容纳一定体积的生长培养基,并用于检测由假定包含在测试样品中并被添加到生长培养基中的一种或多种微生物产生的气体,该装置包括一个主腔室、一个由主腔室顶面限定并与之相通的穹顶、该装置包括主室、一个由主室顶面限定并与之相通的圆顶,圆顶确定一个液面并适于收集生长培养基中微生物产生的气体,以及一个与主室一端相邻并相通的填充部分,填充部分与圆顶间隔开并延伸到液面之上,并进一步确定一个用于添加测试样品的开口。该装置可通过一个可拆卸的封闭装置进行密封。还公开了一种由基本相同的装置阵列组成的装置。此外,还公开了使用该装置和设备检测和估计微生物数量以及分析假定含有微生物的样品的方法。
