The overall reaction for microbial conversion of glucose to L-glutamic acid is: C6H1206 + NH3 +1.5 O2 →C5H,NO4 + CO2 + 3H20 (glucose) (glutamic acid) a) If 18 grams of glutamic acid are produced, how many grams of ammonia are required? Assume 100% conversion of ammonia b) What mass of glucose is required to produce 25 g of glutamic acid? Assume 100% conversion of glucose Atomic weights: C=12, H=1, N=14, O=16.
