In this paper emphasis is placed on the utilization of fermentative production of L-glutamic acid in the pilot plant with formerly isolated Brevibacterium dicaricatum nov. sp. using 500-L and 50-KL fermenters.
It was found that the yield of L-glutamic acid was higher than 45% in each case on the base of consumed glucose when the hydrolysates of Cassava starch (Tapioka flour) was employed as sugar source.
The greatest advantage observed in this experiment was the remarkable reduction in time required for fermentation in comparison with the fermentation time necessary for the laboratory method. This is a very favourable factor for the industrial preparation of L-glutamic acid.
