Patent ID: 8741611

Claim:
An Aspergillus oryzae host cell comprising a heterologous polynucleotide encoding a malic acid transporter, wherein the malic acid transporter is selected from the group consisting of: (a) a malic acid transporter comprising an amino acid sequence having at least 95% sequence identity with SEQ ID NO: 8; (b) a malic acid transporter encoded by a polynucleotide that hybridizes under very high stringency conditions with the full-length complementary strand to SEQ ID NO: 7; and (c) a malic acid transporter encoded by a polynucleotide comprising a nucleotide sequence having at least 95% sequence identity with SEQ ID NO: 7; and wherein the host cell is capable of secreting at least 50% more malic acid compared to the host cell without the heterologous polynucleotide encoding the malic acid transporter when cultivated under the same conditions.
