2. A strain of mold was grown in a batch culture on glucose and the following data were obtained. \begin{tabular}{|c|c|c|} \hline Time $(\mathrm{h})$ & Cell Concentration $(\mathrm{g} / \mathrm{l})$ & Glucose Concentration $(\mathrm{g} / \mathrm{l})$ \\ \hline 0 & 1.2 & 100 \\ \hline 9 & 2.4 & 97.1 \\ \hline 16 & 5.1 & 90.4 \\ \hline 23 & 10.5 & 76.9 \\ \hline 30 & 22.0 & 48.1 \\ \hline 34 & 33.0 & 20.6 \\ \hline 36 & 37.5 & 9.4 \\ \hline 40 & 41.0 & 0.6 \\ \hline \end{tabular} a) Calculate the maximum growth rate. b) Calculate the substrate yield. c) What is the maximum cell conc. one could expect if $150 \mathrm{~g}$ of glucose was used with the same size inoculum?
