anaerobic nitrogen oxidation plays major role in wastewater treatment performed by planctomyces look up chem eqn
use of hydrogen as an electron donor stronger donor than most organic compound produced by fermentations in anaerobic environments dehalorespiration
reduction of halogenated organics using H2
ATP production from oxidative phosphorylation using proton gradient and sodium ion gradient
any metabolic pathway performed by methanogenic archaea that produces methane
in what order are electron acceptors used?
order of energy available highest energy acceptors go first lowest energy acceptors go last
what archaeon can oxidize both iron and sulfur?
Iron and sulfur oxidation can cause...
steel corrosion in underwater bridge supports
what organism is added to help in the mining of copper?
hydrogen can be used to reduce _________ to produce methane
________compounds can be disproportionated to produce methan and carbon dioxide
_________- can be dismutated into methan and carbon dioxide
mostly prokaryotes terminal electron acceptors:metals, oxidized nitrogen and sulfur, chlorinated organics. nitrate can be reduced to nitrite nitrite to nitric oxide fumarate to succinate trimethylamine oxide to trimethylamine
light-driven proton pump found in halophilic archaea
in several proteobacteria contained in about 13% of upper water marine bacteria absorbs green light so microbes appear purple contains 7 membrane-spanning helices surrounding retinal protons are pumped through retinal configuration changes
reduction of oxidized states of nitrogen for energy
nitrifiers generate ______ and __________ by oxidizing ammonia
nitrite and nitrate
redox potentials generally are lower than oxidized nitrogen forms coupled to acetate and hydrogen oxidation microbes generally only perform part of the pathway individually
sulfulobus oxidize _________________ to ____________
hydrogen sulfide to sulfuric acid
