Voges-Proskauer Test with Leifson's Reagent
At. Most bacteriologists held that the old Voges?SKauer's test (1898) was not a satisfactory test for the differentiation of the coli-serogenes group of organisms. During carbohydrate fermentation by the aerogenes group of bacilli, acetoin (acetylmethyl carbinol) is formed, and this is detected by caustic potash and peptone. Acetoin is oxidized to diacetyl, and this reacts with caustic potash a...
متن کاملVoges-proskauer Test: Expeditious Techniques for Routine Use.
The standard methods of performing the VogesProskauer (VP) test (see Eddy, J. Appl. Bacteriol. 24:27, 1961) require an incubation period of 2 days or more. This is an impediment to the utilization of the test, as time is a precious commodity in many situations. Techniques requiring a shorter incubation period have been proposed by Eddy and also by Pickett and Scott (Bacteriol. Proc., p. 110. 19...

متن کاملPractical substitution for the indol, methyl red, Voges-Proskauer, citrate system.
A substitution for the indole, methyl red, Voges-Proskauer, citrate system is proposed. The scheme employs indole and ampicillin susceptibility tests routinely and uses selectively three other media for six reactions.
متن کاملEffect of acetate upon the formation of acetoin in Klebsiella and Enterobacter and it possible practical application in a rapid voges-proskauer test.
Acetate stimulates the formation of acetoin during 1-h incubation of Voges-Proskauer-positive strains of Klebsiella and Enterobacter. Of these organisms, 124 of 126 strains were recognized as positive in the presence of acetate, and 106 were recognized as positive in its absence.
