Upgrading Whey

Comments (0)

Whey is a waste product from the cheese industry. In this experiment students upgrade whey, by converting the lactose into glucose and galactose, or by growing the microorganism K.lactis on agar containing whey.

Cheese companies are currently developing ways of upgrading the whey so that they can increase their profits and reduce the serious pollution problems associated with disposal.
