1. (3.5 points total) Bacteria with the formula C10H1304N2 (MW = 225.0 g/mol) is grown in a batch reactor on sugar bagasse (C11H1809, MW = 294.0 g/mol) as the carbon source for the production of lutein (C40H56O2, MW = 568.0 g/mol). The mass balance equation for this reaction is shown below. The rate of cell growth is 1.125 g cells/L*h and the rate of product production is 0.284 g P/L*h. The yield of product on substrate (YP/s) for this process is 0.096599 g product/ g substrate. Use the MWs given here to solve this problem.
