None. Lactose comes from milk.
Lactose is used as a selective nutrient in the agar as not all microbes can process lactose
tolerates
The negative control in the lactose experiment would be a sample that does not contain lactose or the enzyme needed to break down lactose. This control is used to show what would happen if no lactose were present for the enzyme to act on.
Yes, Hafnia is a lactose fermenter. It is a Gram-negative bacterium which can ferment lactose to produce acid and gas. This characteristic can be used for its identification in microbiology.
Double strength lactose broth is used to selectively culture lactose fermenting bacteria. It contains a higher concentration of lactose compared to regular lactose broth, allowing for more efficient differentiation of lactose fermenters from non-fermenters based on acid production. This medium is often used in microbiology laboratories for various tests and experiments.
I am from New Zealand, and I think that not that much New Zealnders are lactose and tolerant....
Sugar as a general term means cane sugar which is absent in lactose but lactose is also a disacharide sugar found in milk , its common name is milk sugar.

Lactose-free milk still contains milk sugar, but the lactose has been broken down into simpler forms that are easier to digest. Therefore, lactose-free milk may still contain some level of sugar from lactose, depending on the processing method used.
LACTOSE sugar
It aids in digestion of lactose
