Document Summary
Includes many of the most commonly encountered bacteria. Most metabolically diverse phylum: chemolithotrophs, chemoorganotrophs. Means its slower growting because it has to start from. Facultative organisms that can switch from one metabolic lifestyle to another. Example of a non-pathogen: rhizobium leguminosarum (need to know) The bacteria provide fixed nitrogen (form of nitrogen that plants can actually use), and the plant gives the bacteria a favorable niche for it to survive (continuous amount of nutrients, protected area) Bacteria fixes nitrogen into a bioavailable form. Plant provides nutrients and a home for the bacteria. Millions of these bacteria in these nodules providing plant with nitrogen. Example of a pathogen: rickettsia rickettsia, obligate intracellular pathogen, fig. Cant survive on its own, needs a hot cell: carried by insectsand transmitted by insect bites. Transmitted directly into blood stream: causes rocky mountain spotted fever . Metabolically diverse, some are pathogens, some are nono-pathogens.
