Transgenic strain for producing succinate and method for producing succinate

A transgenic strain for producing succinate, comprising:

• an autotrophic host cell;
• and
• a plurality of exogenous genes within the host cell, comprising:
• a first exogenous gene, which is a gene encoding a-ketoglutarate decarboxylase (Kgd) or a gene having 80% or higher sequence identity to SEQ ID NO:
• 1 and having Kgd activity;
• a second exogenous gene, which is a gene encoding succinate semialdehyde dehydrogenase (GabD) or a gene having 80% or higher sequence identity to SEQ ID NO:
• 2 and having GabD activity;
• a third exogenous gene, which is a gene encoding citrate synthase (GltA) or a gene having 80% or higher sequence identity to SEQ ID NO:
• 3 and having GltA activity;
• and
• a fourth exogenous gene, which is a gene encoding phosphoenolpyruvate carboxylase (Ppc) or a gene having 80% or higher sequence identity to SEQ ID NO:
• 4 and having Ppc activity,
• wherein expression of at least one of native genes encoding glucose-1-phosphate adenylyltransferase (GlgC), succinate dehydrogenase subunit A (SdhA), and succinate dehydrogenase subunit B (SdhB) is suppressed in the host cell.
