How canacid production by glucose and lactose fermentation be differented in the same tube?
To differentiate acid production by glucose and lactose fermentation in a test tube one must look at the neck and the butt of the test tube. Different colors indicate fermentation or non-fermentation.
What are the product of lactate fermentation?
it is called lactose fermentation and it yields lactic acid + gas .....the acid can be recognized by chemical indicator ( Bromocresol) and the gas can be recognized my trapping the gas in an inverted tube ( Durham tube ).
If the bacteria can not use citrate what will the results be in the citrate agar test?
If bacterium cannot use glucose the fermentation tube will stay the same color. Gas may also occur inside the fermentation tube.
What is the durham fermentation tube?
A Durham fermentation tube is a test tube that has a second inverted tube inside used to capture fermented gas (CO2) byproducts of bacteria. Typically the tube has a pH indicator in it, like phenol red, that will change color when acid is present (in this case to yellow). Gases are trapped inside the Durham tube, while the indicator shows the production of acid. Low pH is caused by Lactic Acid.
Is the liquid portion of a specimen collected in a tube containing EDTA is serum?
No, it is called plasma.
What is Smith fermentation tube?
Smith fermentation tube has a closed vertical arm which extends into a bulbous portion with tapered opening. it is used in observing an organism doing anaerobic fermentation.

What is the purpose of the bromcresol purple in the fermentation tube?
These are both used as pH indicators.

If bacterium cannot use glucose the fermentation tube will stay the same color. Gas may also occur inside the fermentation tube.
What will the neural tube become?
The brain and spinal cord. The cephalic portion of the nueral tube becomes the brain, the caudal portion becomes the spinal cord.
Why isn't a pH indicator needed in the lactose broth fermentation tube?
not sure bro
