Method for making succinic acid, anaerobiospirillum succiniciproducens variants for use in process and methods for obtaining variants

摘要

A method for making succinic acid employs a fluoroacetate resistant variant of Anaerobiospirillum succiniciproducens. The fluoroacetate variant produces a succinic acid product which contains less acetic acid than the product obtained using the parent strain under identical conditions. A preferred variant FA-10 is obtained from A. succiniciproducens (ATCC No. 29305). A method of obtaining the variant also is described.
