3. Microbes in Our Lives
Microbes (microorganisms)–Living things that individually
are too small to be seen with the unaided eye.
They include:
#Bacteria
#Fungi (yeasts & molds)
#Protozoa
#Algae
#Viruses

5. Industrial Uses of Fungi
• Use of yeasts performing fermentation in
brewing, wine making and bread making.
• Use of yeast (e.g. Saccharomyces cerevisae) to
make alcohol.
• In the beer making industry, cereal grains are
fermented to make the final product.
• Sake is produced by rice fermentation, using
Aspergillus oryzae.
• Are used industrially in the food industry is in
cheese production. (Penicillium roquefortii)

8. Industrial Uses of Algae
• They are used as fertilizers, soil conditioners and
are a source of livestock feed.
• Algae can be used to make biodiesel (see
algaculture), bioethanol and biobutanol.
• The natural pigments produced by algae can be
used as an alternative to chemical dyes and
coloring agents.
• There is also much interest in the food industry
into replacing the coloring agents that are
currently used with coloring derived from algal
pigments.

14. Industrial Uses of Bacteria
• The discovery that Thiobacillus ferrooxidans can
concentrate gold trapped in rock minerals drew
the attention of mining companies, and they are
now developing a method of applying these
bacteria in the gold mining industry.
• Larger scale applications such as:
•
•

20. Industrial Uses of Protozoa
• Protozoans play important roles in the fertility
of soils.
• Protozoans play important roles in wastewater
treatment processes, in both activated sludge
and slow percolating filter plants.

24. Detection of Microbes in Source and
Drinking Water
• It is done by Molecular Methods.
• Molecular techniques are based on
genomics, proteomics and transcriptomics.
• Clinical and food industries are increasingly
adapting these techniques.

25. Biosensors for the Detection of
Waterborne Pathogens
• Using Antibodies and Gene-Based Recognition
Chemistries .
• Using LAMP for Low Cost Screening of
Multiple Waterborne Pathogens.
• In LAMP, the target sequence is amplified at a
constant temperature using either two or
three sets of primers and a polymerase with
high strand displacement activity.

30. Glossary
• Genomics- The study of genes and their
function.
• Proteomics-The study of the proteome, the
complete set of proteins expressed by an
organism, tissue, or cell.
• Transcriptomics- The study of the
transcriptome, the complete set of RNA
transcripts produced by the genome at any
one time.
