微生物代谢多样性 Microbes have extensive metabolic diversity Photoautotrophy Oxygenic photosynthesis AND anoxygenic photosynthesis Photoheterotrophy(not photosynthesis Use light energy and organic compounds to make biomole cules Only Prokaryotes can do this. Chemoautotrophy Use inorganic compounds for energy to fix CO2 Only Prokaryotes can do ts can be used Several different compounds Chemoheterotrophy Use organic compounds for both carbon and energy Often the same compound is used for both Huge array of organic molecules are food for microbes, in cluding many that are toxic or deadly to other organisms微生物代谢多样性 ▪ Microbes have extensive metabolic diversity – Photoautotrophy ▪ Oxygenic photosynthesis AND anoxygenic photosynthesis – Photoheterotrophy (not photosynthesis!) ▪ Use light energy and organic compounds to make biomole cules ▪ Only Prokaryotes can do this! – Chemoautotrophy ▪ Use inorganic compounds for energy to fix CO2 – Several different compounds can be used ▪ Only Prokaryotes can do this! – Chemoheterotrophy ▪ Use organic compounds for both carbon and energy ▪ Often the same compound is used for both ▪ Huge array of organic molecules are food for microbes, in cluding many that are toxic or deadly to other organisms
