Archaea and Bacteria
Extreme thermophiles
Spirochetes
Extreme halophiles
Methanogens
Pathogenic
Gram-positive bacteria
cyanobacteria
Chlamydias
Proteobacteria
Live in highly saline environment
Thrive in very hot environments
Are strict anaerobes and are poisoned by O2 Live in swamps and MarshLive in swamps and Marsh and produce methane as a waste product
These gram-negative bacteria include photoautotrophs,chemoautotrops,hetrotrophs
Some are anaerobic and other aerobic
Molecule systematic currently recognize five subgroups (alpha,beta,gamma,delta,epsilon)
photoautotrophs that generate O2
These bacteria are parasites that live within animal cells
These bacteria are helical heterotrophs
clostridium botulinum
Staphylococcus and Streptococcus
Bacillus anathrics
Actinomycetes
decompose soil
the cause of anthrax
the cause of botulism
Mycoplasms
can be pathogenic
the smallest cells known
exotoxins
endotoxins
are secreted and cause disease even if the prokaryotic that produce them are not present
are released only when bacteria die and their cell walls break down
