2. WHAT IS ARCHAEBACTERIA?
Archaebacteria Definition
• Archaebacteria are the oldest organism living on earth. They are
unicellurar prokaryotes-microbes without cell nucleus and any other
membrane-bound organelles in their cells and belongs to the kingdom,
Archaea. They were first discovered in 1977 by Carl Woose and George E.
Fox and classified as bacteria. Most archaebacteria appear like bacteria,
when observed under the microscope. However, they are quite different
from bacteria and eukaryotes. Archaebacteria are found in very harsh
conditions such as in the volcanic vents or at the bottom of the sea. They
can easily survive in such extreme environment at sea vents releasing
sulfide-rich gasses, hot spring, or boiling mud around volcanoes.

Halophiles are
organisms that thrive in
high salt concentrations.
They are a type of
extremophile organism.
The name comes from
the Greek word for "salt-
loving".
SCIENTIFIC NAME:
Halococcus and
Halobacterium

 From the greek word “thermotita”
(heat) and “philia” (love).
 Temperature loving organism
 Grows in a temperature of 55-
113°C
 Most found in geothermally
heated regions on earth ex. Hot
spring
 As they need extreme
temperature, ts very hard to study
them under laborotary conditions.
 Also that some members can
produce heat by themselves
compost and garbage landfill
SCIENTIFIC NAME- Thermus Aquaticus

Methanogens are
microorganisms that
produce methane as a
metabolic byproduct in
hypoxic conditions.
They are prokaryotic
and belong to the
domain of archaea.
SCIENTIFIC NAME –
Methanobacterium
thermoautotrophicum
