- Example 14.6 The oxygen requirement for cell growth in glueose can be represented by the following equation (Mateles, 1971) 32NC+8(Nh2)+16(No2) Fx/sM +yo2 – 2.67yc + 1.714YN2 – 8y H2 ro2 = In which ro2 is the oxygen required for each gram of cells produced, N stands for no. of atoms present in each molecule substrate, y stands for mass fractions and M is the MW of the substrate. The yeast cell may be considered to be CH1.800.5NO.2. Calculate rO2 if the yield factor (Yx/s) is 0.46g of cells produced for each gram of substrate consumed.arrow_forwardExtremophiles are microorganisms that can survive and proliferate in extreme environments. One group of such microorganisms are lithotrophs. These are found deep beneath the Earth's surface, living on rocks under anaerobic conditions and surviving on CO2 as their sole source of carbon. Imagine that you are studying a newly discovered lithotroph and are trying to determine what it uses as a source of electrons for reducing CO2 and for producing energy. Which one of the following conditions must be met for a molecule to serve as a useful electron donor? Oxidation of the molecule occurs with a decrease in free energy. Oxidation of the molecule occurs with an increase in free energy. Reduction of the molecule occurs with a decrease in free energy. O Reduction of the molecule occurs with an increase in free energy.arrow_forwardCan autotrophs convert organic molecules into more usable forms of organic molecules?

- One of your friends, Rasta, works at a local wastewater treatment plant (WWTP) in his hometown. Despite the plant having several process steps, Rasta is adamant that the dominant process step is biological treatment which happens in a 500 m3 bioreactor. The water flows to the bioreactor at a rate of 1.6m3/minute. The conditions inside the bioreactor favor extreme production of nitrogen (N), from the degradation of amino acids found in the wastewater, during the first half of each day. By midday the concentration of nitrogen in the bioreactor is almost always 2 mg/L. Since nitrogen is regulated, Rasta must then get the concentration down to half of this concentration within one hour. The influent (into the bioreactor) has no nitrogen. Rasta has two alternatives to facilitate the process. The first option is to increase the throughput rate by 150%. The second option is to keep the normal throughput rate and add an adsorbent “pillow” that removes nitrogen with a rate of 0.01/minute.

The biomass yield from substrate is 0.14 g/g, while the product yield also from substrate is 0.92 g/g. Ammonia is used as a nitrogen source. Based on this information, answer: (a) What is the oxygen demand for acetic acid production in this crop?(b) What are the cooling requirements of a bioreactor containing 3000 L of ethanol (ρ = 789 kg/m³), to be completely converted into acetic acid?arrow_forward
- The synthesis of microbial cellular features (e.g. sugars and amino acids) can be summarized with which of the following statements? Each molecule that needs to be synthesized O has its own unique carbon fixation pathway to ensure that there is no fixation unless that particular molecule is needed. O must be oxidized to generate energy (via the electron transport chain) necessary to conduct biosynthesis. O will be modified from common precursor molecules to meet the needs of the cell. O will be passed through one of the glycolytic pathways to form pyruvate. O must be taken up from the environment in the form necessary to mcet the needs of the cell.arrow_forward5.

"I know that yeast can survive under both aerobic and anaerobic conditions," he says, "but what I don't understand is why they seem to need so much more sugar under anaerobic conditions.
