its all about bioremediation factors that affecting bioremediation hope it will help full for everyone.

BIOREMEDIATION

2. TABLE OF CONTENT
• Factors affecting bioremediations:
Moisture
Nutrients
Oxygen level
PH
Temperature
Chemical nature of pollutants

3. FACTORS AFFECTING BIOREMEDIATI0N
1)MOISTURE:
• It influence the rate of contaminants metabolism because it
influence the kind and amount of soluble materials that are
available as well as the osmotic pressure and ph of aquatic an
terrestrial system.
• A range of 50-80% is optimal for biodegradation.

4. 2) NUTRIENTS:
• Nitrogen, phosphorous, potassium, sulfur, copper and trace
elements etc. are required.
• If nutrients are not available in sufficient amounts microbial
activity will become limited.
• Nitrogen and phosphorous are deficient in contaminant
environment. These are usually added to the bioremediation
system in a useable form ( e.g. As ammonium for nitrogen and
as a phosphate for phosphorous.)

3) OXYGEN LEVEL:
• Increasing the concentration of electron acceptors and
nutrients in ground water and surface water.
• Oxygen is the main electron acceptor for aerobic
bioremediation.

6. 4) PH:
• Soil PH may effect the availability of nutrients.
• PH of 6.5 to 8.5 is generally optimal for biodegradation in most
aquatic and
• And terrestrial systems and value ranging.

7. 5) TEMPERATURE:
• Temperature directly influence the rate of biodegradation by
controlling the
rate of enzymes catalyzed reactions.
Temperature of 15 to 65C is optimal for biodegradation.

8. 6) CHEMICAL NATURE OF POLLUTANTS:
• In general aliphatic compound are more easily degraded than
aromatic ones.
• Presence of cyclic ring structure and length chains or branches
decreases the efficiency of biodegradation.
• Water soluble compounds are more easily degraded.
• The presence of halogens inhabit biodegradation.
