Bakers' yeast is produced in a 50 000-litre fermenter under aerobic conditions. The carbon substrate is sucrose; ammonia is provided as nitrogen source. The average biomass composition is CH1.8300.55N0.17 with 5% ash. Under efficient growth conditions, biomass is the only major product; the biomass yield from sucrose is 0.5 g g-I. If the specific growth-rate is 0.45 h-l, estimate the rate of heat removal required to maintain constant temperature in the fermenter when the yeast concentration is 10 g l- 1 _______________________.10^6

Identical heat lamps are arranged to shine on two identical containers, one containing water and one methanol (wood alcohol), so that each liquid absorbs the same amount of energy minute by minute. The covalent bonds of methanol molecules are nonpolar, so there are no hydrogen bonds among methanol molecules. Which of the following graphs correctly describes what will happen to the temperature of the water and the methanol?

Pseudomonas putida with mm = 0.5 h-1 is cultivated in a continuous culture under aerobic conditions where D = 0.28 h-1 . The carbon and energy source in the feed is lactose with aconcentration of S0 = 2 g/l. The effluent lactose concentration is desired to be S = 0.1 g/l. If the growth rate is limited by oxygen transfer, by using the following information:
Determine the steady-state biomass concentration (X)
