A bioreactor of working volume 50 m3 produces a metabolite (X) in batch culture under given operation conditions form a substrate (S). The final concentration of metabolite at the end of each run was 1.1kg m-3. The bioreactor was operated to complete 60 runs in each year. What will be the annual output of the system (production of metabolite (X)) in Kg per year?
