Pseudomonas putida is being used to biodegrade toluene in an in-situ, aerobic bioremediation
system. The environmental conditions are oligotrophic, in that Pseudomonas is starved for other
nutrients and organic carbon/energy sources, including toluene, which is present at low
concentrations (S0 = 5 mg/L). It is able to perform oxidative phosphorylation using toluene as an
electron donor to obtain ATP as a primary energy source that primarily fuels its biosynthesis
pathways (i.e., fs ~ 1). During this oxidation process, toluene is degraded to a less harmful
metabolite, benzoic acid.
a) Given this information write out the kinetic model to describe the substrate degradation profile
as a function of time.
b) With the information in the Table below, compute the substrate (S) and biomass concentrations
(X) after 3.5 days have elapsed. Assume that the initial degrading population is quite low, given
the oligotrophic conditions (X0 = 0.5 mg/L).

A pure bacterial culture is growing in a warm, oxygenated, and nutrient rich solution present in a
batch reactor system. Given what you know about doubling times:
a) Estimate the specific growth rate of this culture if the generation time is determined to be 40
minutes.
b) If 60 cells are present initially, calculate the mass of cells present after a 16-hour period. Assume
that the biomass weighs 5.7E-10 mg/cell.

His imprint on New York City and its surrounding regions remains evident in highways, parks, bridges, and housing policies. However, his approach to planning often excluded public input and disproportionately harmed communities of color and low-income populations. This assignment challenges you to reflect critically on Moses’ legacy and draw connections to contemporary urban planning challenges. Reflect on Power and Authority in Planning: How did Robert Moses’ accumulation and use of unelected power shape the urban landscape of New York? What lessons can modern planners learn about checks and balances in urban development? Community Impact Analysis: Identify and discuss at least one community or population that was negatively impacted by Moses' planning decisions. What were the long-term effects on that community?

- After watching the video "The Rise and Fall of Robert Moses" (Vox), write a 1-page (approximately 500 words) double-spaced response that addresses the following: Reflect on Power and Authority in Planning: How did Robert Moses’ accumulation and use of unelected power shape the urban landscape of New York? What lessons can modern planners learn about checks and balances in urban development? Community Impact Analysis: Identify and discuss at least one community or population that was negatively impacted by Moses' planning decisions. What were the long-term effects on that community? How might a more equitable planning process have changed the outcome? Contemporary Relevance: Can you identify a current or recent urban planning decision (local, national, or international) that echoes the same issues of power, displacement, or inequity? Compare the two and discuss how modern planners might address these concerns differently.arrow_forwardPlease answer the question in the picture and make sure your work is correct please.
