Bakers’ yeast is produced in a 50,000-litre fermenter under aerobic conditions. The carbonnsubstrate is sucrose; ammonia is provided as the nitrogen source. The average biomassncomposition is CH1.83 O0.55 N0.17 with 5% ash. Under conditions supporting efficient growth,nbiomass is the only major product and the biomass yield from sucrose is 0.5 g /g. If thenspecific growth rate is 0.45 h^-1, estimate the rate of heat removal required to maintainnconstant temperature in the fermenter when the yeast concentration is 10 g/L.
