Does Sarcina test positive or negative for the voges-proskauer test?
negative
What does a positive Voges-Proskauer test mean?
It means that the bacterial organism uses the butylene glycol pathway; producing acetoin (acetylmethylcarbinol). This specific compound is produced only by bacteria that utilize this pathway. Usually (but not always) a positive Voges-Proskauer (VP) test indicates the organism is negative for the methyl red (MR) test. Both the MR and VP tests are usually done using the same culture; after dividing it into two equal volumes.
What test will differentiate between Klebsiella pneumonia and Citrobacter freundii?
K. oxytoca will be indole-positive while K. pneumonia is indole-negative
What indicator is used to determine glucose or lactose in voges proskauer test?
Alpha napthol and a mixture of creatine with KOH
Two tests for reactions that produce acid end products?
Voges Proskauer and Cysteine Test. I think...
Is Staph epi Voges-Proskauer positive or negative?
positive
Does Sarcina test positive or negative for the voges-proskauer test?
negative
What are results of Imvic test on staphylococci?
Staphylococcus epidermidis indole test - negative methyl red - negative voges proskauer test - positive citrate test - no idea

Which test would likely benefit most from longer incubation time methyl red or voges proskauer?
Incubation times for the voges proskauer test should be exactly 48 hours because lengths longer or shorter can skew results. However, methyl red may benefit from incubating longer than 48 hours.
Bacillus cereus have a positive reaction for VP and citrate?
The B.cereus has a positive citrate test and a negative Voges Proskauer.
What is the MRVP?
It is abbreviated MR/VP. MR stands for methyl red, and VP stands for Voges-Proskauer. It is used to identify bacteria producing stable acids by mechanisms of mixed acid fermentation and glucose. I found this on wikipedia.com.
Which reaction definated VP test?
reaction of voges-proskauer test
Why do you read a methyl red test immediately?
The methyl red test is read immediately because fermentation occurs within a short time to produce an acid. Conversely, because oxidation requires more time, the Voges-Proskauer test is read after about an hour.
What test will differentiate between Klebsiella pneumonia and Citrobacter freundii?
K. oxytoca will be indole-positive while K. pneumonia is indole-negative
What indicator is used to determine glucose or lactose in voges proskauer test?
Alpha napthol and a mixture of creatine with KOH
Why you should make methyl red test and voges proskauer always with each other?
MR n VP tests always made wid each other becoz da media used for performing da test is divided into two parts n then used simaltaneously....
