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
