Menskala naik satu proses fermentasi berdasarkan pekali pemindahan isipadu (kLa)oksigen tetap

The production of the enzyme cytochrome P-450 by Saccharomyces cerevisiae N.C.Y.C. 754 in batch fermentations using a coconut water based medium was scaled-up from shake flask to a 2-liter stirred - tank fermenter scale using the method of constant volumetric transfer coefficient (kLa) of oxygen....
