Food is an edible substance that
comes from animals or plants and
can be assimilated by an organism
to produce energy , stimulate
growth and maintainlife.

•Biotechnolgy=
•bios (life)+ techno (tools) + logos (study of)
The study of tools from livingthings.
•It’s any technological application that use biological
systems,living organisms(or parts of living organisms)to
make, modify, impove plants or animals for benificial
use.

Available definations ofbiotechnology:
•Biotechnology is the application of biological organismssystems
or process to manufacturing and servise industries.(British
biotechnologists)
•Biotecnhology is integraed use of biochemestry,microbiologyand
engineering sciences in order to achieve technologicalapplication
of microbes, cultured cells and parts there of (European
federation ofbiotechnologists)
•Biotechnology is the controlled use of biological agents, suchas
microbes or cellular components.(U.S.Nationel science
foundation)
BIOTECHNOLOGY APPLICATIONS:
Medical and pharmaceuticalbiotechnology:
Antibiotics
Vaccines
Humainhormones
(insulin)
Tissueengineering
Stemcells
Cancertherapies
Environementalbiotechnology:
•Biofuel, biodiesel ,biogas
Use bacteria and some plants to cleanup
environmentalwastes
4-FOODBIOTECHNOLOGY:
•Food biotechnology is the application oftechnologies
tomakeormodify animals, plants, and
microorganisms, which have desired production,
marketing, or nutrition related properties to obtein
food.
FOOD BIOTECHNOLOGY APPLICATIONS:
•Plantagriculture:
•Increasedproduction
•Cross breeding
•Herbicide or pesticide resistantplants
•The use soil bacteria « Bacillus thurigiensis » as aninsecticide
TransgenicsGMO
•Transgenic are genetically modified organisms with
DNA from another source inserted into theirgenome
Genes from other species/organisms. Organisms that
have transgenes are called genetically modified
organisms. As their genome is modified .to obteined
caeactreddesired.
Transgenic animals: agriculture use
•chicken
•Salmon
•Beef
