Document Summary
Chapter 4: cell structure and function in bacteria. The study of bacteria is driven greatly by the development of new antibiotics. Craig venter proved that he could sequence dna very quickly; led the. Human genome project: venter decided to pursue new antibiotics since he predicted that soon we will be out, although he has found many, none have been effective in humans. All our antibiotics now are from soil. Organisms send out antibiotics in soil to scare away other bacteria. Researchers have found a new bacteria (elfetheria terrae) which produces a new antibiotic called teixobactin: researchers have an ichip (sp) which can culture unculturable bacteria. 6 that we need to know: proteobacteria: largest. Gram negative: firmicutes: many are gram positive; thick (firm) cell walls, actinobacteria: soil organisms. Affected by penicillin (penicillin attacks gram positive bacteria): cyanobacteria: photosynthesis using chlorophyll. Lots of antibiotics have been found from this phylum of bacteria: chlamydiae: gram negative.
