Vitamins, antibiotics and hormones
Bacteria
Shape
Coccus (Spherical)
Bacillus (Rod-shape)
Spirilium (spiral)
Proteobacteria (Gram-Negative)
Alpha
Agrobacterium- tumors in plants
Used in genetic engineering.
Beta
Soil bacterium Nitrosomas
Gamma
Thiomargarita namibiensis
Salmonella
Legionella
Escherichia coli resides in the intestines
Delta
Myxobacteria- produces drought resistant "myxospores"
Epsilon
Campylobacter- blood poisoning
Helicobacter Pylori- stomach ulcers
Chlamydias
Live in animal cells
Causes blindness
Spirochetes
Helical heterotrphs
Treponema, pallidum (syphilis) and borrelia.
Cyanobacteria
Photoautotrophs
Involve in the process of endosymbiosis
Gram positive Bacteria
Actinomycetes- decomp soil
Bcillus anthracis- cause of anthrax
clostridium botulinum- cause of botulism
staphylococcus
Mycoplasms- smallestknow cells
Archea
Euyarchaeota
Thamarchaeota
Aigarchaeota
Crenarchaeota
Korarchaeota
Ecological Interctions
Biofilm
Teeth plaque
Symbiosis
Two species ive in close contact: larger-smaller
Mutualism
Both organism benefit
Commensalism
one benefit, the other is neither harm or helped
Parasitism
exotoxins-
secreted and cause disease.
endotoxins
Released only when bacteria die.
