1. A population having a biomass of 2 mg/L at t = 0 days reaches a biomass of 139 at t = 10 days. Assuming exponential growth, calculate the value of the specific growth coefficient.
2. A bacterial population with a maximum specific growth rate of 1 day-1 and a respiration-rate coefficient of 0.2 day-1 will be applied in cleaning up an organic chemical spill. To quickly attain a low final steady-state chemical concentration, would a higher or lower half-saturation constant be re-quired?
