Part III: Ro \& Rc calculation For a 1,3 Propanediol (C3H8O2) - PDO - production organism (C1H1.8O0.5N0.2) a first chemostat experiment is performed and measurements are made when the chemostat is at steady state. PDO is produced aerobically using glucose (C6H12O6) as a substrate and NH4+as N-source. The chemostat feed, Fin in m3/h, contains glucose and (NH4)2SO4 dissolved in water. Air sparging, with rate FN,in in mol/h3, is used to supply O2 to the organism and to remove CO2. The dry sparged air contains much more CO2 than normal and its composition is 21%O2;0.5%CO2 and 78.5%N2. Question 1 0.0/1.0 point (graded) Which balance do you use to calculate R0 ? broth O2-balance gas CO2-balance gas O2-balance broth CO2-balance Calculate R0; give the correct units. Question 3 1 point possible (graded) Which of the following terms are negligibly small or do not apply to the balance used to calculate R0 ? TN,O Co,inFin Co,outFout dtd[VLCO] TN,C RO
