폴리글루탐산 발효에서 two impeller를 사용한 산소전달 계수의 향상 |
| 초록 |
Poly ((-glutamic acid) ((-PGA) produced by microorganism is completely biodegradable, water-soluble, non-toxic to human body. Therefore (-PGA can be used as water-soluble and biodegradable polymer in various applications including thickeners, humectants. Secretion of (-PGA into culture broth during fermentation made volumetric oxygen transfer coefficient KLa low, and this might induce oxygen limitation that could reduce the productivity of (-PGA. The dependence of KLa on various factors such as position, size and number of impeller was studied. Locating two impellers on the upper part of air sparger and at two third of the total liquid height from the vessel bottom was most effective for oxygen transfer in 5 L fermenter
