Strains
The A. oryzaestrain NRRL3488 was used as a wild-type strain and served as a parental strain for strain 2103a-68.1 (further
called triple) which overexpresses pyc, mdh, and the putative malic acid transporter C4T318 and was obtained from
Novozymes, Inc. Spores of both strains were stored at −80 °C in 20 % glycerol.
