- •
Malic acid production via PMA fermentation by Aureobasidium pullulans was studied.
- •
High PMA production was obtained from soybean hull hydrolysate and soy molasses.
- •
Soy molasses is the cheaper feedstock without needing prior enzymatic hydrolysis.
- •
Malic acid can be produced from soy molasses at $1.10/kg for a 5000 MT plant.
- •
This offers an economical process for industrial production of biobased malic acid.
