[交流] 求翻译几句话

进入产素期后(48小时后),耗氧在96小时附近达到最大,此后从96小时到144小时,OUR逐渐下降,150小时左右采用OUR监控进行补糖操作,维持OUR在11-12mmol/Lh附近,结果表明,菌丝干重(DCW)在144小时达到峰值,而后因菌体自身衰老等原因,因补料速率根据在线OUR监控,比生长速率(μ, h-1)维持很低的水平,这样有利于次级产物的分泌。这表明,补糖速率采用在线 OUR监控后能及时反映菌体的生长状态,尤其是,比生长速率,因为低的比生长速率对次级代谢有利。

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.
