BIOL 2051 Chapter : Need To Know Microbes 1
Document Summary
Mycoplasma genitalium- the smallest free-living pathogenic bacterium 0. 2 microns. Thiomargarita namibiensis the largest prokaryote 750microns; spherical sulfur chemolithotroph. This simple transport of lactose uses h+ bound to lactose to transport it into the cell. Mycoplasma & chlamydia are the only species of bacteria that lack cell walls. Planctomyces is a species of bacteria whose cell walls are completely made up of protein. Usually bacteria have peptidoglycan which are sugars linked together with protein. Methanobacterium is a archea that has a pseudomurein cell wall (see study guide) Halococcus is archea that is also an extreme halophile that has a polysaccharide cell wall. Attached to some polysaccharides is a uronic acid. Attached to uronic acid is a sulfate group that binds na+. Myxococcus have twitching motility which is a form of gliding that uses pili to move. Thiospirillum jenense is photosynthetic, so it aggregates at light wavelengths at which its pigments absorb.
