Abstract
Bacteria of the genus Neisseria can be detected in a sample by separating a lysate of the sample into two parts, incubating one part with a solution of nicotinamide-adenine-dinucleotide (NAD) and 1,2-propanediol, incubating the other part with a solution of only the NAD, and then comparing the products of each incubation for reduction of NAD to NADH. A difference in NADH concentration indicates the presence of any enzyme specific to Neisseria, this enzyme having the capability of oxidizing 1,2-propanediol and reducing NAD. The structure of the enzyme is not completely understood but, because of those two characterizing properties, the nomenclature 1,2-propanediol dehydrogenase therefor is proposed herein.
