The product formation is strictly growth- associated. X from substrate = 10 g substrate. 0. 6 0. 3 g dcw g substrate. X max = x: + x from substrate(ok if they left out xo) L or 1. 80 g dcw. = 0. 924 hr 1 ln 2( ) = 5. 63 hr (t should be about the same if they used 1. 8 g dcw. X = x o e t ln 2( ) t d ln. X o t : determine the value of the maintenance coefficient (g substrate/g dcw- h). (6 pts) 10% of the substrate goes to maintaining the cells. g substrate.
