VOLJNO Lactose-fermenting bacteria metabolize lactose using two proteins, one binds external lactose and transports it into the cell, the other breaks down the lactose that comes into the cell. The two proteins are coded for by two genes that are under the control of a single promoter. You carry out a lactose fermentation test on an unknown bacterium and find that the result is positive. All of the following are applicable to this bacterium growing in the lactose broth, EXCEPT:...
