WHAT IS
BIOTECH?
Biotech is the study involving the
use of living organisms to carry
out processes that we want.
THE DIFFERENT TYPES OF BIOTECH
●
●
●
●
●
Bacteria
Yeast
Enzymes
Penicillin/Antibiotics
Genetic Engineering
BACTERIA BIOTECH AND USES FOR IT
Bacteria is the most common type of microorganism used in biotech. They
are useful because they can produce complex molecules (eg certain bacteria
added to milk produce enzymes that turn the milk into yoghurt)​.They are also
useful because they reproduce rapidly, meaning the amount of chemicals
they can produce can also rapidly Increase.
Common uses of biotech that use bacteria:
• Bread
• Beer
• Milk
YEAST BIOTECH
AND USES FOR IT
Yeast is a single celled fungus that uses
sugar as its food source. ​When it
respires, ethanol and carbon dioxide are
produced (and energy is released)​. The
ethanol produced in this reaction is
increasingly being used as a biofuel (a
fuel made from living organisms rather
than a fossil fuel like oil, coal or gas)​.
Common uses of biotech that use
yeast:
• Biofuel
• Bread-making
ENZYMES BIOTECH AND USES
FOR IT
Enzymes are biological catalysts (also known as biocatalysts)
that speed up biochemical reactions in living organisms, and
which can be extracted from cells and then used to catalyst a
wide range of commercially important processes.

Common uses of biotech that use enzymes:
Fruit Juice Production
Biological Washing Powder
Lactose-Free Milk
PENICILLIN/ANTIBIOTICS BIOTECH
AND USES FOR IT
Penicillin was the first antibiotic discovered in 1928 by Alexander Fleming in the fungus
Penicillium. The penicillium mould produces a chemical to prevent it being infected by
certain types of bacteria. The chemical was isolated and named penicillin​. Since the
discovery of penicillin, methods have been developed to produce it on a large scale,
using an industrial fermenter​​
Common uses of biotech that use penicillin:
• Medicine
GENETIC ENGINEERING BIOTECH AND USES FOR IT
Genetic engineering is changing the genetic material of
an organism by removing, changing or inserting
individual genes from another organism​. The organism
that undergoes genetic engineering is called GMO
(genetically modified organism). The DNA of the
organism that now contains DNA from another
organism as well is known as ‘recombinant DNA’.
Common uses of biotech that use genetic engineering:
• Human growth hormones.
• Vaccines.
WHY BIOTECH
IS
IMPORTANT?
Modern biotechnology provides breakthrough
products and technologies to combat
debilitating and rare diseases, reduce our
environmental footprint, feed the hungry, use
less and cleaner energy, and have safer,
cleaner and more efficient industrial
manufacturing processes.
BIOTECH’S
EFFECT ON
SOCIETY
Bio tech could help address many global
problems, such as climate change, an aging
society, food security, energy security and
infectious diseases. By using biotech, we
are able to use less energy, less resources
and less manpower. This is essential for
creating a sustainable future
HOW BIOTECH
IS GOOD FOR
THE
ENVIROMENT
Products developed with agricultural biotechnology may
contribute to the reduction of greenhouse gas emissions,
such as cover crops that provide sustainable biofuels ,
fruits and vegetables that stay fresh longer and reduce
food waste.
RELIGIOUS VIEWS ON BIOTECH
Biblical Views On Genetic Engineering
While there aren’t many concerns over the use of most biotech, genetic engineering
does have a bit of controversy. While many any Christians do not forbid the use of
genetic engineering, they have some concerns such as:
• Changing genes in humans could cause a situation where “man tries to take the place
of his Creator” resulting in “an unjust domination of man over man.”
• A bold pursuit of advances in genetic engineering might be motivated by a defiance of
God.
• Genetic engineering may interfere with the God-ordained process of life.
• Genetic engineering may take on a role beyond that which God has given to us as
stewards of His creation.
• Genetic engineering could preclude God’s plan for the restoration of creation.
