Abstract

The effect of agitation speed and aeration rate on mTG production and cell growth by Streptoverticillum morbarense was investigated. Dissolved oxygen was controlled by on-line computer-controlled fermentation system. The agitation speed and aeration rate of 2.5 L fermentor ranged from 330 to 360 게m and 1 vvm to 4 vvm, respectively. The highest mTG production was 2.1 U/mL when dissolved oxygen level was 20%, and it was improved almost 1.1 times in comparison with that without dissolved uxygen control.
