Factors into the production period (48 hours), oxygen consumption at maximum near 96 hours, then from 96 hours to 144 hours, OUR decreased, about 150 hours to fill with sugar OUR monitoring operation, the maintenance of OUR in the 11-12mmol / Lh in the vicinity, the results show that the mycelium dry weight (DCW) reached its peak in 144 hours, then cell itself due to aging and other reasons, due to feed rate according to line OUR monitoring, specific growth rate (μ, h-1) to maintain low level, it is conducive to the secretion of secondary products. This shows that the rate of use of carbohydrate supplement line OUR monitoring timely to reflect upon the cell growth state, in particular, the specific growth rate, because of low specific growth rate of the secondary metabolic advantage. |
