Solution: Mass of medium = 1000 L * 1000 g/L = 1,000,000 g or 1000 kg. Energy required = 1000 kg * 4.2 kJ/kg°C * (37°C - 20°C) = 1000 * 4.2 * 17 = 71,400 kJ.

Solution: Power per unit volume = 2 kW / 2000 L = 0.001 kW/L or 1 W/L. Bioprocess Engineering Basic Concepts 2nd Edition Solution

Solution: Assuming no cell growth or death, the total amount of cells remains constant at 1000 g. After adding 500 L of medium, the total volume becomes 1500 L. The new cell concentration is 1000 g / 1500 L = 0.67 g/L. Solution: Mass of medium = 1000 L *

Solution: Using the equation for sterilization, N(t) = N0 * e^(-kt), where N0 is the initial number of spores, k is the death rate constant, and t is time. N(15) = 10^6 * e^(-0.5*15) = 10^6 * e^(-7.5). Solution: Assuming no cell growth or death, the
