Two continuous stirred-tank fermenters are connected in series, the first having an operational volume of 100 L and that of the second being 50 L. The feed to the first fermenter is sterile and contains 5000 mg/L of substrate, being delivered to the fermenter at 18 L/h. If the microbial growth can be described by the Monod kinetic model with µm= 0.25 h-1 and Ks = 120 mg/l. What would happen if the flow were from the 50 L fermenter to the 100 L fermenter?

1. What do you think is the ideal world human population size? Is this different than humans’ carrying capacity? Explain.

2. What policies or methods might encourage smaller families in developing countries? Focus on positive changes that encourage CHOOSING smaller families instead of focusing on government-mandated requirements.

3. In many developing countries, larger families are desired, while developed countries tend to prefer smaller families. What factors influence these decisions?

4. A declining population rate has its own problems. Discuss what issues may arise for the country as it transitions to a falling fertility rate.

5. Who do you think has a bigger role in curbing the effects of human population growth: the countries with high fertility rates or the countries with high consumption rates? Explain.

Q5 - Anthropogenic Carbon Flux

What is the total anthropogenic flux to the atmosphere, including both fossil fuels and land use, in PgC? We're looking for the flux to the atmosphere, not the net flux (don't subtract out red fluxes from atmosphere to land or ocean).
