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 is the result of Benedict test in lactose?
I know that with Fructose it turns red and forms precipitate
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 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 reaction would saccharolytic bacterium give in a TSI tube?
The saccharolytic bacterium in a TSI tube would liberate sulfates inside the tube turning it yellow. The TSI tube is triple sugar iron agar, which tells us if the bacterium can live in glucose, sucrose or lactose.
