1. Bacteria & Archaea

2. Rhizobium Rhizobium
Leguminosarum
• Description: Rhizobium forms an
endosymbiotic relation with the
roots of legumes and Parasponia.
They colonize plant cells inside
the root nodules. This bacteria
provides organic nitorgenous
compounds to the plants while
the plants give the bacteria
organic compounds made
through photosynthesis.

3. Nitrosomonas Europaea
• Description: Nitrosomonas Europaea
is a chemolithoautotroph, which
means it derives its energy from
reduced mineral sources. It lives in
soil, sewage, freshwater, and on
building surfaces especially in
polluted sections with high
concentration levels of nitrogen
compounds in the air. Cell division
can take up to several days do to the
large amounts of ammonia needed
by this bacteria.

4. Thiomargarita namibiensis
• Description: Thiomargarita
Namibiensis is found off the
shore of Nambia in the ocean
sediments of the continental
shelf. It is the largest
bacterium ever discoveredand
can be seen by the naked eye.
Small granules of sulfur are
trapped in the long chains of
this bacteria and that gives it’s
yellow appearance. It is
chemolithotrophic .

5. Chondromyces Crocatus
• Description: Chondromyces
Crcatus forms fruitbodies
like that of fungi and
therefore were first
mistaken for a fungus. It
turned out that it was a
bacterium. The clusters at
the top of the streams are
consists of many bacteria of
this species that send out
rods from themselves to
connect with other cluster.

6. Bdellovibrio bacteriovorus
• Description: Bdellovibrio
bacteriovorus is found just
about anywhere including the
intestines of a human being.
They do prefer marine
habitats. They cannot
reproduce by themselves so
they invade a larger bacterium
and kill it to use its remains to
make more of itself.

7. Helicobacter pylori
• Description: Helicobacter
pylori is found in the stomach.
About 50% of the world
population has this organism
in their upper intestinal tracts.
The presence of this bacteria is
slowly disappearing in western
countries. About 80% of
people infected with this
bacteria show no symptoms.
Symptoms such as nausea,
stomach and abdominal aches,
acute gastritis, and non-ulcer
dyspepsia.

8. Chlamydia Trachomatis
• Description: Chlamydia
Trachomatis are parasitic
microorganisms that grow and
reproduce inside the cells of a
host. It can cause pelvic
inflammatory disease, cervicitis,
and ectopic pregnancy in
women. In men it can cause
prostatitis and epididymitis. It
can also cause blindness .

9. Borrelia Burgdorferi
• Description: Borrelia
Burgdorferi is a human
pathogen. They have an
LPS-like substances in their
outer membrane. They also
have an inner membrane
and a periplasmic space
that contains a layer of
peptidoglycan. It is the
cause of Lyme disease.

10. Oscillatoria princeps
• Description: Oscillatoria
Princeps is commonly found
in nature. Mostly in aquatic
environments such as
ponds. It can perform
anoxygenic photosynthesis .
They are the only
prokaryotes to generate
oxygen like plants with
photosynthesis.

11. Clostridium Botulinum
• Description: This bacteria
produces many toxins. It is
well known for its neurotoxins
that it produces. These toxins
cause flaccid muscular
botulism. This usually starts in
the face and then moves
towards the limbs. They are
shaped like a rod. Oxygen is
poisonous to them but they
can survive with only small
traces of it.

13. Archaea

14. Pyrococcus Furiosus
• Description: Pyrococcus Furiosus
is an extreme thermophile. In
biotechnology it is used as a
source of DNA polymerase for
PCR techniques. It has optimal
growth at 100 degrees celsius.
This temperature would kill most
organisms. It also has an enzyme
containing tungsten, which is rare
to find in biological molecules.

extreme thermophile
Geogemma Barossii can
double its numbers in 121

16. Haloquadratum walsbyi
• Description: Its cells are
flat and square shaped. It
thrives in extreme salt
conditions and therefore
it is halophilic, which
means salt loving. It can
be pretty much found
anywhere in hyper saline
waters.

17. Nanoarchaeum Equitans
• Description: This species
was discovered in
hydrothermal vents off
the coast of Iceland. It is a
thermophile because it
thrives in extreme heat.
Its genome is only
490,885 nucleotides long.
The cells are only 400 nm
in diameter.
