Chapter 18, Problem 1AQ

Design an experiment for measuring the activity of sulfuroxidizing bacteria in soil. If only certain species of the sulfur oxidizers present were metabolically active, how could you tell this? How would you prove that your activity measurement was due to biological activity?

You have evaluated the rate of aerobic degradation of organic matter in an industrial wastewater and found that it does not follow normal Monod kinetics. After some testing, you have found that the substrate degradation rate follows the following relationship instead: -rut = k0.5XaS0.5 where -rut = substrate utilization rate (mg/L•day) k = 4 (L/mg•d2) S = substrate concentration (mg/L) Xa = active microbial concentration (mg/L) You have also determined coefficients of bacterial growth on this substrate under aerobic conditions to be Y = 0.25 g VSSa/g substrate and b = 0.08/d. (VSSa, active volatile suspended solids) Estimate the effluent substrate concentration when treating the above wastewater in a CSTR (continuously stirred tank reactor) with recycle while operating at a θx (MCRT, mean cell residence time) of 4 day.
For an experiment where you use different concentrations of avocado catalase to determine how it affects the rate of reaction with its substrate, hydrogen peroxide, what would be the independent variable? What would be the dependent variable?
Under anoxic conditions, biological denitrification of waste water by activated sludge results in the conversion of nitrate to nitrogen gas. Sludge is microorganisms, and these microorganisms carry out this reaction, this is a biological reaction. When acetic acid provides the carbon source, the reaction can be represented as follows: 5CH3COOH + 8NO3 → 4N2+ 10CO2 + 6H20 + 8HO Acetic acid Nitrate a) Is the stoichiometric equation balanced? write down the number of atoms of each species on left side and also on the right side of this equation. b) In the absence of side reactions, what is the yield of nitrogen from acetic acid in g g1? c) A certain waste water contains 6.0 mM acetic acid and 7mM NaNO3. If 25% of the acetic acid and 15% of the nitrate (NO3) are consumed in other reactions (e.g, for growth of the microorganisms in the sludge), which is the limiting substrate in the denitrification reaction? d) For the situation described in part c), what mass of gaseous nitrogen (N2) in…
