Culture comprising a B. subtlis strain by inoculating 1g of cells into 1 liter bioreactor. Fermentor containing 10g/l of glucose. The maximum specific growth rate of the culture is 1.0 /h. The biomass yield from glucose is 0.5 g/g. If the residual glucose concentration left out is 1g/l, the final cell concentration in g/l achieved would be around
