The growth rate of the phototrophic purple bacterium Rhodobacter is about twice as fast when the organism is grown phototrophically in a medium containing malate as the carbon source as when it is grown with CO2 as the carbon source (with H2 as the electron donor). Discuss the reasons why this is true, and list the nutritional class in which we would place Rhodobacter when growing under each of the two different conditions.
Answer to relevant QuestionsAlthough physiologically distinct, chemolithotrophs and chemoorganotrophs share a number of features with respect to the production of ATP. Discuss these common features along with reasons why the growth yield (grams of ...What are some ways that diazotrophs protect nitrogenase from O2? Contrast the life cycle of Hyphomicrobium with that of Caulobacter. Describe a key feature that would differentiate each of the following Bacteria: Streptococcus, Planctomyces, Verrucomicrobium, and Gemmata. How can organisms such as Halobacterium survive in a high-salt environment, whereas an organism such as Escherichia coli cannot? (Section 16.1)
