How can you tell if a bacterium can metabolize casein in the casein digestion test?
Homework Answers
Casein is a milk protein. Casein gives an opaque color to the milk agar plate.
If the bacteria is metabolized casein, it secretes casease which degrade casein protein into smaller peptides.
When the bacterium, which was grown in the milk agar plate metabolize casein, turn the opaque color of milk agar into a clear plate. change in color from opaque to colorless shows the bacteria is metabolizing casein.
Please write to me if you need more help.

You are studying a bacterium that utilizes a sugar called athelose. This sugar can be used as an energy source when necessary. Metabolism of athelose is controlled by the ath operon. The genes of the ath operon code for the enzymes necessary to use athelose as an energy source. You have found the following: The genes of the ath operon are expressed only when the concentration of athelose in the bacterium is high When glucose is absent, the bacterium needs...

In a casein agar test, a bacterial species grows well on the agar, and creates a clear zone around its colonies. This bacterium must be: NEG POS Select one: a. releasing proteinase enzymes into its surroundings. b. oxidase enzyme positive as well. C. utilizing citrate as its main source of carbohydrate. d. able to turn SIM agar to black in color.

VOLJNO Lactose-fermenting bacteria metabolize lactose using two proteins, one binds external lactose and transports it into the cell, the other breaks down the lactose that comes into the cell. The two proteins are coded for by two genes that are under the control of a single promoter. You carry out a lactose fermentation test on an unknown bacterium and find that the result is positive. All of the following are applicable to this bacterium growing in the lactose broth, EXCEPT:...
