BIOL 2051 Chapter : CHAPTER 17 20
Document Summary
70s ribosomes but functionally similar to eukaryotes; methionine. Official publication of the new species name and description in international journal of. Systematic and evolutionary microbiology (ijsem): bergey"s manual of systematic bacteriology and the prokaryotes are major taxonomic compilations of. Undiscovered bacteria: many species uncharacterized, many bacteria cannot yet be grown, unclassified organisms. Identified solely through rrna sequence: environmental samples rrna is sequenced, many bacteria (majority?) still unknown. 104-105 cells/ml in: gram positive bacteria, divided into 2 groups: low gc firmicutes & high gc actinobacteria based on % of guanine & Earthy odor of: 60+ antibiotics, mycobacteria, acid fast due to mycolic acids, some human pathogens, ex: tuberculosis, leprosy, many are slow-growers, mycobacterium, gram-negative proteobacteria and nitrospirae, largest, most metabolically diverse group of bacteria, alpha proteobacteria. 1st identified by rrna sequencing; little is known about them: spiral shape, nitrite oxidizers; obligate aerobes, some species are found in microbial mats near hot springs, bacteroidetes and chlorobi.
