Consider the growth of a microorganism in batch culture. When the substrate concentration is high, the cell density doubles every 0.75 h, the observed substrate yield coefficient is 0.3 g DCW/g, and substrate consumption is allocated towards biosynthesis (60%), maintenance (10%), as well as product formation (30%). The product formation is strictly growth-associated. The batch reactor is inoculated with 0.01 g DCW/L and 10 g/L substrate. Estimate the maximum cell density (after lag phase).

In a 3-input CMOS NAND gate, the substrate terminals of NMOS transistors are grounded (lowest potential available in the circuit) and the substrate terminals of PMOS transistors are connected to VDD (maximum positive potential available in the circuit). Which of the following transistors may suffer in this circuit from the body bias effect?
A given substrate may be acted upon by a number of different enzymes, each of which uses the same substrate (s) and produces the same product (s). The individual members of a set of enzymes sharing such characteristics are known as-
What is the yield coefficient if the initial substrate concentration is 10 g/l and biomass is 0.1 g/l. The substrate is then consumed and produces 5.3 g/l of biomass?
What is the yield coefficient if the initial substrate concentration is 20 g/l and biomass is 0.2 g/l. The substrate is then consumed and produces 6.0 g/l of biomass?
In a substrate X catabolic gene promoter you replace the normal histones by your experimental histones – ones with arginine side chains in place of histidine. What will be the effect on the concentration of substrate X against the control?
