A chemolithoautotroph is respiring using only iron (Fe3+) and nitrite (NO2-). This bacterium does not consume organic molecules.
How does this organism make NADH?
Azotobacter vinelandii is being studied for the production of alginate from sucrose. In a continuous culture at 28°C with ammonia as a nitrogen source, the alginate yield obtained was 4 g/g of oxygen consumed. It is desired to produce alginate at a rate of 5 kg/h. As the viscosity of alginate in water is considerable, the energy related to stirring the broth cannot be neglected, and the fermenter is equipped with a Rushton-type turbine. For satisfactory agitation and aeration speed, the estimated energy requirement is 1.5 kW. Calculate the cooling requirement.
