MIC102 Bacteria

midterm 2

cyanobacteria

oxygenic photosynthesizer, can fix nitrogen, filamentous or colonial, neat differential potential

green sulfur bacteria

anaerobic photolithoautotroph, anoxygenic photosynthesis. chlorosomes have pigments

spirochete

free living anaerobic. has an axial filament that lets it spin around in corkscrew motion to move through viscous environments. can also hide flagella if wanted

alphaproteobacteria

gram negative, interact with diseases or symbiosis. mitochondrial ancestor.

betaproteobacteria

gram negative, important pathogens

gammaproteobacteria

gram negative, mammal interactive

deltaproteobacteria

gram negative, unique respiration

epsilonproteobacteria

needs low level of oxygen to grow (microaerophillic). gram negative, gut inhabitants and extremophiles.

zetaproteobacteria

gram negative, iron oxidizing

actinobacteria

gram positive, high guanine + cytosine content in dna. lives in the soil and has fungus-like mycelium . produce streptomycetes which are antibiotics

firmicute

gram positive, low guanosine + cytosine content, can form endospores. high amount of genetic exchange and variability

crenoarchaeota

thermoacidophiles, use sulfur in metabolism. not all are extremophiles.

methanogens

can survive off of methane, often in anaerobic environments.

halophiles

grow in high-saturation salt environments

paramecium

macro and micronucleus, can divide mitotically a limited number of times

plasmodium

has apicoplasts, cause malaria, lives in red blood cells and targets human liver.

diatoms

unicellular algae, plankton. photosynthetic
