1. Environment biotechnology

2. introduction
• Environmental biotechnology is the
application of biotechnology for solving
environmental problems, both in the
environment or in man made ecosystems.

3. Contaminants released into the environment
• Solvents
• Pesticides
• Herbicides
• Fungicides
• Insecticides
• Petrochemicals
• Explosives
• Heavy metals

4. Environment biotechnology deals with
• Decontamination of environmental
components
• Production of chemicals biosensors
• Pollution prevention
• Waste minimization

5. Environmental biotechnology
includes
• Bioremediation
• Biosensors
• Bioindicators
• Pollution prevention

6. bioremediation
• A practice in which microbiological
process are used degrade or transforms
contaminants to less toxic or non toxic
forms

7. Process considering in
bioremediation
• Physically removal of contamination
• Separation of contamination from medium
• Degradation
• immobilization

8. Bioremediation includes
• Waste water treatment
• Soil bioremediation
• Solid waste bioremediation
• Biotreatment of gaseous streams
• Biodegradation of hydrocarbons
• Biosorption

9. Biosensor
• Environmental biosensor are the analytical
device composed of biological sensing
elements and a physically transducer
which together relate to measure able
signal

11. Types of biosensor based on transduction
signal
• Electrochemical
• Optical
• Piezoelectric
• Thermal sensor

12. Types of biosensor based on
biorecogination principal
• Microorganism
• Enzymes
• antibody

13. Bioindicators
• Biological indicators are the species that
can used to monitor the environment of
ecosystem
• Example is copepods

14. Pollution prevention
• Use biotechnology approach to produce
products biologically and environment
friendly

15. It includes
• Modification of bioremediation and
degradation
• Pulp and paper industry
• Chemicals
• Use enzymes in detergent
• Bioenergy from biomass
• Biorefinery
