Bacterial cells exhibiting formate dehydrogenase activity for the manufacture of succinic acid

A Pasteurella bacterial cell comprising a heterologous polypeptide having formate dehydrogenase activity, wherein the bacterial cell has increased succinic acid production relative to a corresponding control bacterial cell, the bacterial cell characterized by the 16S rDNA of SEQ ID NO:

• 7 or a 16S rDNA at least 99.9% identical thereto, wherein the heterologous polypeptide having formate dehydrogenase activity is encoded by a polynucleotide comprising a nucleic acid selected from the group consisting of:
• a. a nucleic acid having a nucleotide sequence as shown in SEQ ID NO:
• 5,
• b. a nucleic acid encoding an amino acid sequence as shown in SEQ ID NO:
• 6;
• c. a nucleic acid which is at least 90% identical to the nucleic acid of a) or b);
• and
• d. a nucleic acid encoding an amino acid sequence which is at least 90% identical to the amino acid sequence encoded by the nucleic acid of a) or b).
