MICR 106 - EX3 - Eukaryotic taxonomy

Extreme halophiles

thrive in salt contents of more than 25%

Extreme thermophiles

Thrive in temperatures above 80C

Extreme acidophiles

found at pH below 2

Methanogens

anaerobic archaea that produce methane as an end product 

Alphaproteobacteria

Gram negative, capable of growth at very low nutrient levels

Betaproteobacteria

Gram negative, use nutrients that diffuse away from areas of anaerobic decomposition (hydrogen, ammonia, methane

Gammaproteobacteria

Gram negative, largest group of proteobacteria

Deltaproteobacteria

Gram negative, predators on other bacteria

Campylobacteria

Gram negative, helical or curved rods

Cyanobacteria

Gram negative, oxygenic photosynthetic bacteria, “Blue-green algae”

Chlorobi/Chloroflexi

Gram negative, anoxygenic photosynthetic bacteria

Chlamydiae

gram-negative do not have peptidoglycan in their cell walls, obligate intracellular parasites

Planctomycetes

Gram negative, resemble archaea in cell wall structure, have proto-organelles that resemble eukaryotic nucleus

Bacteroidota

Gram negative, anaerobic bacteria, often found in intestinal tracts of animals and aid in digestion

Fusobacteria

Gram negative, spindle-shaped bacteria

Spirochaetes

Gram negative, coil shaped bacteria that move like a corkscrew

Bacillota

Gram positive, low G+C content in DNA

Mycoplasmatota

Gram positive, lacking a cell wall

Actinomyceota

Gram positive, high G+C content in DNA

Deinococci

Gram positive cocci, often found in extreme environments
