PROBLEM TO BE SOLVED: To provide: a novel bacterial strain designated DD1, which has the ability to produce organic acids, in particular, succinic acid (SA), which has been isolated from bovine rumen, and is capable of utilizing glycerol as a carbon source; and variant strains thereof.SOLUTION: The invention provides a process for producing succinic acid by cultivating a microorganism in the presence of glycerol, glucose, fructose, maltose, sucrose, or the like. The invention also provides a process for the production of tetrahydrofuran and/or 1,4-butanediol and/or γ-butyrolactone, and pyrrolidone from succinic acid. The microorganism is Mannheimia succiniciproducens MBEL belonging to genus Mannheimia, and is a Gram-negative bacillus or coccobacillus. |
