g lactose metabolism. Second, they added two genes that convert galactose into tagatose.
Thus, when the yeast is fed lactose, its own metabolism drives it to produce a solution that is 90% tagatose much higher than the 30 percent yield from traditional manufacturing.
Yeast reactors also operate on much larger scales than enzyme-based ones, which could allow for efficient mass production of tagatose, Jin said.
Another advantage is that our yeast-based process can use whey indirectly. Whey is
