Practical 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 کاملVoges-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 کاملThe Fermentation of Acetyl-Methyl-Carbinol by the Escherichia-Aerobacter Group and Its Significance in the Voges-Proskauer Reaction.
The ability of certain members of the Aerobacter genus to ferment acetyl-methyl-carbinol is indicated by their transitory Voges-Proskauer reactions. These strains produce acetylmethyl-carbinol from glucose and, consequently, yield positive Voges-Proskauer reactions after incubation for from one to three days in Clark and Lubs' medium (1915). When incubation is continued for longer periods, howe...
