Abstract
In accordance with the invention there is provided a method for identifying or testing an anaerobic microorganism wherein an aqueous suspension of a culture of the microorganism having a culture density of about 2.times.10.sup.8 cells/ml, is brought into contact with an aqueous solution containing an oxidation-reduction indicator which substantially irreversibly undergoes a change in color upon being reduced and a biodegradable test substrate compound which, when catabolized by a microorganism, will engender reduction of the indicator, said aqueous suspension containing nutrient in a concentration sufficient to support microorganism culture growth without engendering reduction of the indicator when said suspension contacts said solution, and said suspension also containing a compound which reduces O.sub.2 but does not reduce the indicator.
