Procedure

An aqueous solution medium having a composition of 10% of glucose, 0.5% of ammonium sulfate, 0.15% of potassium primary phosphate, 0.1% of magnesium sulfate, 0.001% of ferrous sulfate, 0.001% of manganese sulfate, 300 μg/l of thiamine hydrochloride, 350 μg/l of biotin, 5 ml/dl of Aji-Eki® and 0.5% of ammonium acetate, at pH 7.0, was charged in an amount of 300 ml into separate small sized glass jar fermenters. After sterilizing in an autoclave, the various L-histidine-producing bacterial strains shown in Table 14, which had been previously grown in bouillon slants at 30° C. for 24 hours, were inoculated thereon. Then, incubation was carried out at 31.5° C. for 48 hours at 1200 rpm at an aeration rate of 1/2 volume per minute, while keeping the pH at 6.5 by the addition of ammonia gas. After completion of the fermentation, the yield of L-histidine produced and accumulated in the solution based on glucose was determined and is shown in Table 14.
