HalococcusdombrowskiiThis bacteria is found inareas with very high saltconcentrations, and can growaerobically or anaerobically,meaning they are facultativeanaerobes.
Escherichia coliThis is a gram-negativeorganism, and is commonlyfound in the intestines ofwarm-blooded organisms.Most E. coli strains areharmless, but some can befatal.
MethanopyruskandleriThis bacteria can survive andreproduce in temperatures ashigh as 122 degrees Celsius. Itlives in environments thathave a lot of hydrogen-carbon dioxide and reduces itto methane so it can be usedby other organisms.
NitzschiakerguelensisThese organisms are usuallyfound in cooler waters, andhave even been seen to strivein temperatures as low as -6degrees Celsius. Some ofthem even have very hightolerances to salt, becausethey have discovered speciesliving in Makgadikgadi Pan,Botswana, which is a largesalt pan.
ThermoplasmaacidophilumThis organism is aheterotrophic prokaryote. Itis said to be "among the mostacidophilic organismknown.” It grows in hightemperatures and a very lowpH.
Thermococcus celerThis organism requires hightemperatures to live andthrive, as well as sulfur. It isan obligate anaerobe.
RickettsiaprowazekiiThis gram-negative, parasiticbacteria is most commonlyfound in the feces of lice. Thebacteria usually has twohosts throughout its life, avertebrate and aninvertebrate.
BifidobacteriumdentiumThis bone-shaped gram-positive bacteria that is alsoan opportunistic pathogen. Itis an obligate anaerobe.
Clostridium difficileThis is a gram-positivebacteria that causes severediarrhea along with otherintestinal issues when otherbacteria in your gut havebeen killed by antibiotics.This bacteria can lead tosevere inflammation of thecolon.
Bacillus cereusThis is a gram-positivebacteria that is commonlyfound in the ground. Somestrains of this bacteria cancause foodborne illness,while others are beneficial. Itis the cause of “Fried RiceSyndrome,” which is basicallyjust food poisoning in ricebecause it has sat in roomtemperature too long.
Nodularia armorciaThis is a nitrogen-fixingbacteria. It tends to live insalinic waters, and has evenbeen found in theMakgadikgadi Pans. Thisbacteria occasionally causesheavy algal blooms.
ChlamydiatrachomatisThis is a pathogen in humansthat causes many problems,such as infertility andinfections in the eye. Inwomen, it can cause pelvicinflammatory disease, as wellas many other things.
TreponemapallidumThis bacteria causes manydiseases such as syphilis,beiel, pinta, and yaws. Theorganism is too thin to beseen under a lightmicroscope.
HalobacteriumsalinarumThis organism is extrememlyhalophilic and gram-negative. It is found in saltedfish, hides, saltern lakes, andmany other areas with veryhigh salt concentrations. Itcan also be found in high-sodium foods, like salt porkand sausages.
RhizobiumleguminosarumRhizobium leguminosarumwas the first species ofRhizobium to be identified in1889. The name Rhizobiummeans “root of life.” It is a soilbacteria that requires a planthost to take part in notrogenfixation.
