Lactose is also called "milk sugar" because it comes from milk. Think LACTose, like in lactate, lactation, etc.
The source of lactose is cows. Lactose is a type of a sugar substance that is found in milk. If someone is alergic to milk it is usually the lactose.
The source of lactose is cow's milk.
It means that the organism can use Lactose as an energy source
Bacteria preferentially utilize lactose as a carbon source.

Probably because that is where the gram negative bacteria have found a food source. Lactose is not the perfered diet, but it works and they are most likely there because they can tolerate the environment, and survive (on lactose) when their #1 food source is not available.
lactulose is manufactured by enzymatic isomerization of lactose.
the lacZ gene encodes b-galactosidase, a key enzyme in lactose metabolism. Which lactose is present in the cell, the cell expresses lacZ and metabolizes lactose. source (Matseringbiology.com and campbell biology)
Yes, Citrobacter freundii can metabolize lactose or citrate as a carbon source.
Lactose and sucrose provides the carbon source in EMB plates
It's pink, since it can use lactose as it's nutrition source
in the absence of glucose or lactose , some bacteria are able to use citrate as only source of carcon. alkaline pH change the bromothymol blue indicator from green to blue. pseudomonas can not ferment the glucose and the lactose so it use the citrate as carbon source.
