A culture consisting of 100 litres of nutrient medium containing 12 g l-1 of growth limiting substrate is inoculated with 10g of bacteria in a batch fermenter. The yield of biomass from substrate is 0.05 g g-1 . The maintenance coefficient is 2.0 g g-1 h -1 . The specific rate of product formation due to maintenance is 1.0 h-1 . The maximum specific growth rate of the organism is 0.3 h -1 . YPX= 7.7 and product formation is directly linked with metabolism.   a) What is the time required to produce 15 g of biomass?
