It has been observed that white loght can suppress both cell growth and protein secretion in Baker's yeast. This effect was explored in batch liquid fermentations. Possible applications of this phenomenon are (a) use as a tool for pre-concentrating excreted enzymes prior to subsequent purification and (b) an engineering variable for regulation yeast fermentations.
