Archaebacteria
adapted to hostile conditions (like those of early Earth)
Methanogens
methane makers" live in swamps, sewage, animal guts(o2 free places)
Halophiles
salt lovers" live in brackish ponds & salt lakes; spoil salted fish, animal hides
Thermophiles
heat lovers" live in acidic soil, hot springs
Eubacteria
most prokaryotes, have fatty acids in plasma membrane
Chemoautotrophs
cycle nitrogen & other nutrients through the environment
Chemoheterotrophs
most bacteria is heterotrophic; decomposers, human helpers (food production, bacteria in gut aid digestion)
Photoautotrophs
cyanobacteria (blue-green algae), photo synthetic, so oxygen releasing
Bacillus
rod shaped bacteria
Coccus
round shaped bacteria
Spirillium
spiral shaped bacteria
pickles, buttermilk, cheese, yogurt, sauerkraut, olives, vinegar
Bacteria aids in food producion
clean oil spills, help mine elements, E. Coli in gut helps digest fat, antibiotics
Bacteria aids in industry
Who discovered bacteria(bacteriologist)?
Alexander Fleming
Describe the cellular process of antibiotics.
Antibiotics have been ineffective against some bacteria. These resistant bacteria can pass on their resistance from one generation to the next.
