Microbial diversity and groups
Archaebacteria
split into
two major groups
Euryarchaeota
Nanoarchaeum and Aciduliprofundum
Archaeoglobales
Thermococcales and Methanopyru
Thermoplasmatales
Methanogenic Archaea.
Extremely Halophilic Archaea.
requirement
for high
salt concentrations
. Typically require at least 1.5 M (~9%) NaCl for growth
Crenarchaeota
Inhabit temperature extremes
Algae
Red Algae
Red algae are also called
rhodophytes
Green Algae
Fungi
Most
fungi are
multicellular
and
some
of them
unicellular
(yeast)
Nearly all plants depend on
symbiotic fungi
known as
mycorrhizae
Study of fungi is called
Mycology
Most
fungal cell walls are made of
chitin
Most
fungi reproduce
by asexual means (three forms)
Growth and spread of hyphal filaments
Asexual production of spores
Simple cell division
Viruses
General properties
Viruses can be classified on the
basis of the hosts
they infect
Bacterial viruses (bacteriophages)
Archaeal viruses
Animal viruses
Plant viruses
Other viruses
Living characteristics of viruses
Nonliving characteristics of viruses
Reproduction
1-Adsorption of the virus
2-Penetration
3-Blocking of cell information
4-Synthesis of virus components.
5-Release of the virus
lysis
exocytosis
According to the shape, viruses can be classified into the following groups
Spherical. With a size ranging from 18 to 150 μm
Rod-shaped represented by the tobacco mosaic virus.
Cuboid. With a size ranging from 210 to 305 μm.This form is found in cowpox and canary pox viruses.
Complex-shaped. The size varies from 10 to 225μm
