摘要：
By simulating the evolution of the actual power input observed in shake flasks it was possible to produce, in a fermentor, alginates having a very similar mean molecular mass (1700 kDa) to that obtained in the cultures developed in shake flasks (1800 kDa). Similar profiles of dissolved oxygen tension and oxygen transfer rate could be the reason. (C) 2008 Elsevier Ltd. All rights reserved.
