•Live in extremely harsh
environmentssuch as:
a. hotspring
b. volcanic vents
c. sewage treatment plants
d. environments with high
salt contents
Thermophiles
Methanogens
Halophiles

16. •This organisms are “Heat –
lover”
•Live in very hot temperature.
-usually in 100 °C
Thermophiles

17. •Are anaerobic archaeansthat
releases methane gas
utilized as
BIOGAS
Methanogens

18. •Thrive in extremely salty env’t
such as salt lakes and
evaporating ponds.
•They can withstand 15-30%
salinity of water.Halophiles

•also known as “True bacteria”.
•they are usually unicellularand
microscopic
•their cell wall is made up of
peptidoglycan
•can be found in: a. waterb. soil
c. air
