Question Answer
Anaerob oxidation Nitrat reduktion Assimilativ: nitrat -> ammonium (fleste prokaryote) Dissimilativ: nitrat respiration: nitrat -> nitrit (mange fakultativt anaerobe/mikroaerofil) denitrifikation: nitrat -> nitrit -> nitrogenoxid -> lattergas -> N2 (fakultativt anaerobe/mikroaerofil)
Anaerob oxidation Sulfat reduktion Dissimilativ sulfat reduktion (δ-proteobakterier) Campylobacter, reducerer svovl, sulfit, thiosulfat
Homeoacetogenese Ofte Gram-Positiv H2 + CO2 -> Acetat
Metanogenese Udelukkende Archaea H2 + CO2 -> metan (CH4) CH3COOH -> CH4 + CO2
Forgæring redox uden ekstern terminal e- acceptor - danner ATP v. substrat-level fosforylering
Oxidation redox med ekstern terminal e- acceptor - danner ATP v. oxidativ fosforylering
Saccharomyces Alkoholforgæring
Lactobacillus, Lactococcus, Streptococcus Mælkesyreforgæring
E. coli Blandet syre-forgæring
Clostridium Smørsyreforgæring
Syntrofi Interspecies H+ transfer
Energikilde Fototrof Kemotrof lys kemisk
Elektron-doner Litotrof Organotrof metal organisk materiale
Kulstofkilde Autotrof Heterotrof CO2 organisk carbon
