Pseudomonas methylotrophus is used to produce single-cell protein from methanol in a 1000 m³ pressure-cycle airlift fermenter. The biomass yield from substrate is 0.41 g g^{- 1}, K_S is 0.7 mg l^{- 1}, and the maximum specific growth rate is 0.44 h^{- 1}. The medium contains 4% (w/v) methanol. A substrate conversion of 98% is desirable. The reactor may be operated either in batch or continuous mode. If operated in batch, an inoculum of 0.01% (w/v) is used and the downtime between batches is 20 h. If operated continuously, a downtime of 25 d is expected per year. Neglecting maintenance requirements, compare the annual biomass production from batch and continuous reactors?
