Can yeast metabolize Maltotriose?

Yeast cells harbor several -glucosidase isoforms. While some isoforms are able to hydrolyze both maltose and maltotriose [13,15,30], other isoforms are specific for -methylglucoside [ 15,23 ].

Can maltose be fermented?

Mixtures of maltose and glucose were found to ferment at the same rate as glucose itself as long as an adequate concentration of glucose was maintained in the mixture. Maltose therefore did not act as an inhibitor in glucose fermentation. The intimate mechanism of the maltose-concentration effect is obscure.
