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?
During cheese production, LAB convert lactose to lactate and casein (milk protein) to amino acids. Lactate and amino acids then become the substrates for further microbial growth, which results in aroma production and deacidification of the cheese. The yeast Yarrowia lipolytica grows on the surface of many cheeses; it is capable of both lactate and amino acid catabolism. When grown on a lactate plus amino acid medium, Y. lipolytica preferentially consumes amino acids. Amino acid degradation results in the release of ammonia, which increases the pH. Draw a flow chart that shows the LAB fermentation of milk, followed by the growth of Y. lipolytica. Indicate which substrates are consumed first and what happens to the pH. Based on this simplified scenario, why do you think most cheeses involve the activity of more than one yeast species?
