What are some polysaccharides of carbohydrate?
I have a huge poly sack in my pants
Is corn a cellulose?
I believe corn is a starch.Corn kernels contain sugar (sacharides) and starch (poly-saccharide). The stalk (stover) is lignin (poly-phenol) and cellulose (also a poly-saccharide).
Explain the purpose of the phenol red in the medium?
To determine if a bacterium can ferment a particular carbohydrate and determine the end products of that fermentation
What is another name for a polysaccharide?
(poly)(sacchar)ides poly meaning MANY sacchar meaning Sugar it doesnt give a word for it
Phenol Red is used in carbohydrate fermentation testing because?
Phenol Red is used in this testing because it offers a mid-range pH balance. The color changes from red to yellow when the test is complete.
What culture media can be used to test the carbohydrate fermentation?
To test carbohydrate fermentation, common culture media include phenol red broth and MacConkey agar. Phenol red broth contains a specific carbohydrate, and the color change indicates fermentation. MacConkey agar is selective for Gram-negative bacteria and differentiates lactose fermenters, which produce acid, leading to a color change in the medium. Both media are effective for assessing the fermentation capabilities of various microorganisms.
When using the phenol red carbohydrate broth fermentation test at what pH is the pH indicator yellow?
The pH indicator phenol red turns yellow in the fermentation test when the pH drops below 6.8, indicating acid production from fermentation.
What is molisch?
Molisch's Test refers to a chemical test used to test for carbohydrate existence. This is done using carbohydrate dehydration with hydrochloric or sulfuric acid to create aldehydes. These condense a couple phenol molecules to produce purple or red compounds.
Structure of phenol?
phenol
What is the derivative of Phenol?
The derivative of Phenol is Carbolic acid.
Does phenol react with bromine?
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
Can you get phenol from carbolic acid?
Phenol and carbolic acid are actually the same compound. "Carbolic acid" is an older, colloquial term for phenol.
