Microorganism having carbon dioxide fixation pathway introduced thereinto

An acetyl-CoA producing microorganism comprising:

• a microorganism belonging to Enterobacteriaceae or a microorganism belonging to coryneform bacteria;
• and
• an acetyl-CoA production cycle obtained by imparting enzymatic activity of malate thiokinase, and optionally imparting at least one type of enzymatic activity selected from the group consisting essentially of malyl-CoA lyase, glyoxylate carboligase, 2-hydroxy-3-oxopropionate reductase, and hydroxypyruvate reductase, to a microorganism that does not have any of:
• (a) a carbon dioxide fixation cycle having an enzymatic reaction from malonyl-CoA to malonate semialdehyde or 3-hydroxypropionate;
• (b) a carbon dioxide fixation cycle having an enzymatic reaction from acetyl-CoA and CO2 to pyruvate;
• (c) a carbon dioxide fixation cycle having an enzymatic reaction from crotonyl-CoA and CO2 to ethylmalonyl-CoA or glutaconyl-CoA;
• (d) a carbon dioxide fixation cycle having an enzymatic reaction from CO2 to formate;
• or
• (e) at least one selected from the group consisting of malate thiokinase and malyl-CoA lyase,
• wherein none of (a), (b), (c), or (d) is imparted to the microorganism, or the microorganism exhibits none of the functions of (a), (b), (c), and (d) even though at least one of (a), (b), (c), or (d) is imparted.
