Microbes in Our Lives
Microbes (microorganisms)–Living things that individually
are too small to be seen with the unaided eye.
#Fungi (yeasts & molds)
Industrial Uses of Fungi
• Use of yeasts performing fermentation in
brewing, wine making and bread making.
• Use of yeast (e.g. Saccharomyces cerevisae) to
• In the beer making industry, cereal grains are
fermented to make the final product.
• Sake is produced by rice fermentation, using
• Are used industrially in the food industry is in
cheese production. (Penicillium roquefortii)
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
• There is also much interest in the food industry
into replacing the coloring agents that are
currently used with coloring derived from algal
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:
waste processing and bioremediation
production of drugs
manufacture of polymers
Industrial Uses of Protozoa
• Protozoans play important roles in the fertility
• Protozoans play important roles in wastewater
treatment processes, in both activated sludge
and slow percolating filter plants.
Industrial Uses of Virus
• Measles virus used to kill cancer cells.
• Viruses are Used to Grow more energy
• Used for biological pest control.
Detection of Microbes in Source and
• It is done by Molecular Methods.
• Molecular techniques are based on
genomics, proteomics and transcriptomics.
• Clinical and food industries are increasingly
adapting these techniques.
Biosensors for the Detection of
• Using Antibodies and Gene-Based Recognition
• 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.
• Genomics- The study of genes and their
• 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
