Abstract
PURPOSE: To obtain racemic serine useful as a pharmaceutical, food additive, etc., by culturing the strain of bacteria belonging to Acinetobacter genus, and reacemizing serine in the presence of the cultured product or cultured bacterial cells.
CONSTITUTION: Bacterial strain belonging to Acinetobacter genus, e.g. Acinetobater calcoaceticus ATCC13809, etc. is cultured in a medium containing a carbon source such as glucose, molasses, etc., nitrogen source such as ammonia, meat extract, etc., inorganic materials, etc., under aerobic conditions. Racemization reaction of serine is carried out in an aqueous solution in the presence of the cultured product, cultured bacterial cells separated from the clutured product, or extract of the bacterial cells. The degree of racemization is determined from specific rotation or by bioassay.
