Continuous stirred tank fermenter is characterized by (biomass concentration X kg/m3, residual substrate is S kg/m3, Sf=substrate concentration in feed kg/m3, Dilution rate = D and μm>>D and Km<Sf, XD= the biomass productivity kg/m3h. If the dilution rate is doubled to 2D then the new steady state values in comparison with earlier steady state is characterized by
