Microbiology - Prokaryotes grouped by Metabolic characteristics

Anaerobic Chemolithotroph

no O2/ energy source = inorganic chemicals

Anaerobic chemoorganotroph

No O2, uses SO4 as terminal electron acceptor

What counts as anaerobic chemolithotroph

Archaea and methanogens (methanococcus and methanospirillum)

Methanogens produce ____ as a ____ product

methane, waste

What counts as anaerobic chemoorganotroph

Desulfovibrio desulfuricans/obligate fermenters

WAIT! What even are obligate fermenters

Use pyruvate or other organic compound as electron acceptor

Obligate fermenters example

Clostridium tetani, streptococcus pyogenes, lactobacillus delbrueckii

Aerobic Chemolithotroph

use O2 to oxidize inorganic chemicals

Aerobic chemolithotroph examples

Hydrogenobacter/Nitrobacter/Thiothrix

Hydrogenobacter

Oxidize hydrogen compounds

Nitrobacter

Oxidize nitrogen compounds

Thiothrix

Oxidize sulfur compounds

Aerobic Chemoorganotroph

must have oxygen to oxidize ORGANIC compounds

Aerobic chemoorganotroph examples

Pseudomonas aeruginosa/mycobacterium tuberculosis/micrococcus luteus

Oxygenic phototrophs

energy source = sunlight. Releases oxygen as waste (ex: cyanobacteria aka anabaena azollae)

Anoxygenic Phototrophs

energy source: sunlight. No oxygen release

Anoxygenic phototrophs example

green sulfur bacteria/purple sulfur bacteria
