WebConstantly-fed-batch culture. The simplest fed-batch culture is the one in which the feed rate of a growth-limiting substrate is constant, i.e. the feed rate is invariant during the culture. This case is shown in the graph (here the culture volume is variable). This type … WebEach fed-batch culture was run as duplicate (n= 2). (A) VCD and viability; (B) Titer values relative to the peak titer of the ActiPro™ control culture. In strategy III, daily feeding of 1.1% CB7a/b starting from day 3 maintained relatively low osmolalities despite extensive lactate accumulation up to 3.5 g/L. In a bioreactor setup, low ...
