3.  Introduction
• Member of large group of eukaryotic microorganism.
• Fungi are chemoheterotrophs. They require organic
compounds for energy.
• Fungi are aerobic in nature ( except some yeast, which are
Facultative anaerobic).
• They divide asexually, sexually or by both process.
• They may be unicellular or multicellular.
 The branch of science which deals with study of fungi is
called as Mycology.

4.  MorphologyofFungi
• Fungi show different morphological characters. Depending on cell
morphology, fungi can be divided into four classes :
Fungi
•Dimorphic
Fungi
•Yeast Like
Fungi
Yeast
Moulds

5.  Moulds(FleshyFungi)
• Fungi which form mycelia are called moulds or
filamentous fungi.
• Filaments of fungi are called hyphae .
• Diameter is 2 -10 μm .
• Some hyphae may divided by cross sections called
septa.
• There are two type of hyphae:
1. Septate
2. Non Septate
• Example : Aspergillus niger , Penicillium notatum,etc.

6. • When environmental conditions are favorable , the hyphae grow &
form a mass called Mycelium which is visible to naked eye.
• The portion of mycelium concerned with obtaning nutrients is called
vegetative mycelium.
• The portion concerned with reproduction is called reproductive or
aerial mycelium because it projects above the surface on the medium
on which the fungus is growing .
• The colony may be filamentous , dry or powdery.
• Most of the species are used in production of enzymes and antibiotic.

7.  Yeast
• Round, oval or elongated, unicellular fungi.
• Reproduce by an asexual process called budding in which the
cell develops a protuberance which enlarges and eventually
separates from the parent cell.
• On culture they form smooth, creamy colonies.
• They are aerobic in nature, but some yest are Facultative
anaerobic.
• The optimum temperature for growth of yeast is 25–30 °C.
• Yeast species are used in baking and making alcoholic
beverages.
• Example : Saccharomyces cerevisae, Cryptococcus
neoformans, etc.

8.  Yeast Like Fungi
• In some yeast the bud remains attached to the mother
cell and elongates, followed by repeated budding,
forming chains of elongated chains known as
pseudohyphae.
• They form moist creamy coloured colonies.
• Example : Candida Albicans, Cryptococcus
neoformans, etc.

9.  Dimorphic Fungi
• Mainly pathogenic species exhibit dimorphism i.e. 2 forms of
growth
• Fungi can grow either as a mould or as a yeast.
• Mould like forms produce vegetative and aerial mycellium and
Yeast like forms reproduce by budding.
• Dimorphism is temperature and CO2 dependant.
• At 37 °C, the fungus grows yeast like and at 25 °C it shows
mould like growth.
• Example : Mucor rouxii, Histoplasma capsulatum, Blastomyces
dermitidis , etc.
