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 CH_1.830_0.55N_0.17 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
