MICB 201 Lecture Notes - Lecture 10: Anaerobic Respiration, Planctomycetes, Anammox
Document Summary
The autotrophic way of life, autotrophs use inorganic c (usually co2) as c-source widely distributed in prokaryotic world, where most of bacterial + archaeal phyla have autotrophic members. Diff organisms perform assimilative co2-c reduction differently. Not all use calvin cycle, however many use similar mechanisms metabolism has long evolutionary history in all cases, using co2 as c-source requires both nadph + atp. 10. 2 lithotrophic catabolism in micb 201, lithotroph = organism able to use inorganic chemicals as electron, energy, and carbon sources. Lithotroph = stone/rock-eater, and use inorganic electron source. Restricted to bacteria + archaea; no cases in eukarya. Nearly all bacteria capable of lithotrophy = proteobacteria + Lithotrophic archaea = found in all archaeal lineages: lithotrophs only exhibit respiration and all atp made by oxphos. Some restricted to either aerobic or anaerobic respiration, while others can switch depending on environmental conditions. Respiration of inorganic chemicals (lithotrophic respiration) does not involve.
