Q1During ethanol batch culture fermentation, the specific growth rate of bacterium was calculated as 0.25 h-1. In the aim to enhance ethanol production, a continuous culture was fed with 0.1 g/L of glucose at D = 0.345 h-1 where the growth limiting substrate concentration was 0.01 g/L. The yield coefficient based on glucose was 0.6 g cell/g glucose.A). Evaluate the maximum specific growth rate if the feed glucose was increased by 0.5 g/L while the dilution rate increased up to 0.6 h-1.B). Based on your answer in (a), describe what would be happen if dilution rate is increased up to 0.6 h-1.C). Determine the biomass, 𝑋, at steady- state condition, if the feed glucose was increased to 0.5 g/L. d). Plot the response of the culture in terms of X, S, P and μ after the feed concentration was changed until after new steady state was reached.E) Describe physically in terms of dilution rate and maximum specific growth rate from your answer in (c).
