Abstract
|
|
|
|
A strategy for the automation of glutamic acid fermentation has been developed by the use of CO₂ analyzer together with a controller. It was found that a linear relationship existed between growth and CO₂ level in the exit gas. Therefore penicillin addition at an appropriate biomass concentration to excrete glutamate could be achieved automatically. In addition, an automatic batch feeding method (fed-batch culture) provided a means of overcoming substrate inhibition effects on growth and glutamic acid production in batch culture, thereby increasing productivity and product yield.
