| 제목 | Optimization of Process Variables for High Cell Concentration of Saccharomyces cerevisiae JUL3 in Fed-Batch Cultures |
| 초록 | The β-glucan is one of the most abundant polysaccharides in the yeast cell wall. It shows a variety of biological activities (immunoadjuvants, antitumor, radioprotective agents, etc.). The primary use of β-glucan isolated from the cell wall of yeast is to enhance the immune system. Saccharomyces cerevisiae JUL3 producing highly branched β-glucan was developed through UV mutagenesis and laminarinase resistance. Optimization of molasses and corn steep liquor was performed by using response surface methodology (RSM) for the production of β-glucan by S. cerevisiae JUL3. In this study, we tested process variables such as aeration and agitation, feeding rate in a 2.5L stirred tank reactor (STR) for the production of high cell concentration of yeast.
