dc.description.abstract | For optimal production of L-tryptophan using a regulatory mutant of Escherichia coli the relationship between product formation and acid production was investigated. Experimental results showed that the production level of L-tryptophan was lowered as the specific acid production rate increased. In order to reduce the amount of acid produced during the fermentation, a controlled fed-batch fermentation was employed. In this fed-batch process, the feed rate of the nutrient feed medium was controlled in relation to the oxygen level in the culture and thus the growth of the cells was regulated in such a way that the oxygen demand of the culture could not exceed the oxygen supply. When E. coli cells were cultivated in a controlled fed-batch mode of fermentor operation, the specific production rate was significantly reduced and L-tryptophan production was increased as as five times that obtained in a conventional fed-batch fermentation. | - |
