Smith fermentation tube?
A Smith fermentation tube is a tube that is used for the fermentation of carbohydrates. It also collects any gases that result from the fermentation.

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 ).
What is the purpose of the bromcresol purple in the fermentation tube?
These are both used as pH indicators.
What gas accumulates in the tail portion of a fermentation tube?
Hydrogen and carbon dioxide
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.
Why isn't a pH indicator needed in the lactose broth fermentation tube?
not sure bro
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.
What is the purpose of phenol red or bromcresol purple in fermentation tube?
These are both used as pH indicators.
If an organism oxidatively metabolizes glucose what result will occur in the fermentation tube?
If an organism oxidatively metabolizes glucose the result that will occur in the fermentation tube is yellow. In fermentation, when not enough carbohydrates is added, the bacteria will digest peptones as their carbon source.
What do you do when fermentation is sluggish?
Try warming it up or next time pitch more healthy yeast or watch you tube on yeast starters
