摘要
The cultivation of the yeast Trigonopsis variabilis producing D-amino-acid oxidase (an enzyme participating in the transformation of cephalosporin C into 7-aminocephalosporanic acid for the production of beta-lactam antibiotics) was controlled by changes of dissolved oxygen tension and extended fermentation times. The production technology was optimized on a laboratory scale and scale-up parameters were identified.
