Chapter 12, Problem 3CHI

Magnetotactic bacteria are morphologically and metabolically complex microbes that produce intracellular, membrane-bound magnetic crystals (see figure 3.37). The magnetotactic bacterial isolates called MV-1 and MC-1 both grow chemolithoautotrophically. However, MV-1 uses the Calvin-Benson cycle to fix carbon, whereas MC-1 uses the reductive TCA cycle.

Refer to figures 12.4 and 12.5 to identify key enzymatic steps in each pathway. How do you think the microbiologists studying these fascinating microbes were able to conclude that these two bacterial isolates use two different pathways for carbon fixation?

Read the original paper: Williams, T. J., et al. 2006. Evidence for autotrophy via the reverse tricarboxylic acid cycle in the marine magnetotactic coccus strain MC-1. Appl. Environ. Microbiol. 72:1322.

Imagine you are trying to use an organism to remove organic matter in a wastewater treatment plant (i.e., poop). You would like to maximize the amount of waste consumed while also minimizing the amount of cells produced.   Assuming these organisms exist and all other things are equal, what combination of chemoorganotrophic organism and environment would make the most sense to use? An organism that only has the Entner-Duoduroff pathway under anaerobic conditions. This was a trick question – the organism would have to be a chemolithotroph since it is consuming a chemical. An organism that only has the Entner-Duoduroff pathway under aerobic conditions. An organism that only has the Embden Meyer Parnas pathway under anaerobic conditions. An organism that only has the Embden Meyer Parnas pathway under anaerobic conditions.
The photosynthetic process used by the green sulfur bacteria, under anaerobic conditions, is best represented by which of the following balanced equations? 6CO2 + 12H2O  C6H12O6 + 6O2 + 6H2O 6CO2 + 12H2S  C6H12O6 + 6S2 + 6H2O C12H22O11 + H2O  C6H12O6 + C6H12O6 C6H12O6 + C6H12O6  C12H22O11 + H2O C6H12O6 + 6O2 + 6H2O  6CO2 + 12H2O
Archae are the source of many enzymes used for biocatalysis in diverse industries such as food and feed, pharmaceuticals, detergent, and beverage industries. These enzymes have unique structural and functional properties that enable use under extreme conditions. Use: https://biolres.biomedcentral.com/articles/10.1186/s40659-018-0186-3 for supplemental info What are three classes of extremophiles and their unique growth characteristics? Based on these characteristics, where are they typically found? The functional properties are linked to protein structural characteristics that imparts unique functional properties. For alkaliphiles and thermophiles, what structural elements (or characteristics) within the enzyme structure create these unique properties? See Table 2. Briefly discuss how the unique properties of these enzymes may be beneficial to the design of bioseparation processes. To recover intracellular enzymes, the Archae need to be lysed. Based on their structures,…
