Gastrodin production from p-2-hydroxybenzyl alcohol through biotransformation by cultured cells of Aspergillus foetidus and Penicillium cyclopium.

abstract：:Foam fractionation is one of the low operating-cost techniques for removing proteins from a dilute solution. The initial bulk solution pH and air superficial velocity play an important role in the foam-fractionation process. Denaturation of proteins (enzymes) can occur, however, during the foam-fractionation process f...
