Result Interpretation of Seliwanoff's test: Positive seliwanoff's test: Fructose and sucrose. Negative Bial's test: formation of any other color indicates negative test. Hexose sugar ( glucose, fructose) generally gives green, red or brown color product.
The phenol red thread test is used clinically and is very easy to perform. Patients generally tolerate it well as only a soft thread is touched to the lid and the results are obtained in 15 seconds per eye. Due to the relatively quick assessment, it is useful for examining the tear volume before and after insertion...
Glucose is a sugar that some bacteria can use because of an enzyme that begins the breakdown of this compound. Phenol red glucose (dextrose) broth is thus used to determine whether the microbe can use the sugar glucose for carbon and energy. When many microbes ferment glucose they produce gases, mainly carbon dioxide and hydrogen. These gases ...
Results expressed as slant/butt A=acid, K=alkaline; gas or no gas; H2S or no Interpretation: Butt: yellow = glucose fermented; red or unchanged = can’t ferment glucose Slant: yellow (A) = other sugar(s) fermented red (K) = cannot ferment others, glucose used aerobically, runs out of glucose and aerobically
Sep 11, 2011 · The control in this experiment was the test tube containing the phenol red solution, but no elodea plant. This was the control, because there was no contaminant in the solution, and so if any color change occurred within the vial, it could be determined that it was not in relation to the elodea plant.
Microbiology 20 Biochemical Unknown – Spring 2009 (due May 14th) You should be prepared to turn in your notebook with your biochemical unknown identification completed after lab on Thursday May 14th.
Inoculate tubes with test organism and incubate at 35 ± 2°C for 18 - 48 hours. Observe for color change. The appearance of a yellow color is the indication of fermentation, with or without gas production. Phenol Red Broth Base is used for the carbohydrate fermentation studies of many microorganisms.
A blood glucose test measures the amount of glucose in your blood. It may be used to help diagnose or monitor diabetes. If your results show higher than normal glucose levels, it may mean you have or are at risk for getting diabetes. High glucose levels may also be a sign of

Urease test media contain 2% urea and phenol red as a pH indicator. An increase in pH due to the production of ammonia results in a color change from yellow (pH 6.8) to bright pink (pH 8.2). Urea broth (Stuart’s urea broth) is a highly buffered medium requiring large quantities of

Glucose Fermentation Test: Test to determine if the microbe can ferment the sugar glucose. The microbe is grown in a broth that contains glucose and the pH indicator, phenol red. If an organism is capable of fermenting the sugar glucose, then acidic byproducts are formed and the pH indicator turns yellow. Image obtained from

Used to distinguish between enteric bacteria. In this test the bacteria are grown on Triple SUgar Iron agar. Has a peptone base and contains the pH indicator phenol red, which is yellow below 6.8. Also contains glucose (0.1%) sucrose and lactose (1%) and FeSO4
Feb 28, 1998 · Table 1 presents the test results of R. anatipestifer strains obtained by the conventional test procedure and the BSS test. Despite extensive retesting, the reference strain of R. anatipestifer did not show signs of acid production from carbohydrates in phenol red broth base but acidified glucose, fructose, mannose, maltose and dextrin in buffered carbohydrates. (ii) With addition of sugar and indicator (phenol red), may be used to study fermentation property of Neisseria. (c) Selective and Indicator Medium: (1) MacConkey’s agar (Fig. 10.12): Red, opaque solid medium in 45 mm radius petriplates, slants in test tubes. Composition and sterilisation. Uses:

Phenol red is an acid-base indicator. Acid-base indicators are substances, which change colors depending upon the pH of the solution. Phenol red will change from red to yellow when the medium has a pH < 6.8 (more acidic) and from red to fuchsia when the medium has a pH >7.4 (less acidic). We will use two different kinds of phenol red broths. One contains glucose and one contains sucrose. If your bacterium . is. able to metabolize (eat) the sugar through the process of . fermentation

Phenol Red (PR) Broth is a differential test medium prepared as a base to which a carbohydrates is added. Included in the base medium are peptone and the pH indicator phenol red. We will inoculate PR Glucose Broths with three organisms to determine their fermentation characteristics. Q1. Suppose you innoculate a PR broth with a slow-growing ...
(KIA) Glucose fermentation & Peptone catabolized (K/K) No fermentation & Peptone catabolized Control (uninoculated) (KIA, H2S) Glucose fermentation & Peptone catabolized, Sulfur reduction If there is a black precipitate acid conditions must exist in the butt and we assume the butt would be yellow (A) if we could examine it Phenol red broth is a test that is differential for gram negative bacteria. It tests for three different things: the the ability of a microbe to ferment glucose, the ability to degrade amina acids, and the ability to produce gas as a byproduct of fermentation. The tube starts out orange colored.

Methyl Red was the next biochemical test to be done, which the result was positive for glucose fermentation and mixed acids. The Urea test was the final test. The results were positive for urease, which eliminated all but Staphylococcus epidermidis as the Gram-positive unknown microorganism for the mixed culture of unknown 101. Phenol Red Broth is a general-purpose differential test medium typically used to differentiate gram negative enteric bacteria. It contains peptone, phenol red (a pH indicator), a Durham tube, and one carbohydrate (glucose, lactose, or sucrose).
