Describe the traits that separate archaea from other single-celled organisms. Describe the ubiquitous nature of microorganisms. In general, animals are identified as being multicellular, heterotrophic by digestion, and reproducing sexually. Within the Kingdom Animalia we use diffe...
In marine sediments, two microbial guilds responsible for the terminal degradation of organic matter are strictly anaerobic acetogenic bacteria and methanogenic archaea. Both specialized microbial groups, respectively, reduce carbon dioxide (CO2) to acetate and methane by the reductive acetyl-CoA pathway ...
