Bioremediation of drilling Oil-Based mud wastes
Bioremediation of drilling  Oil-Based mud wastes
 
Applications:
 - Remediation of liquid and solid oil contaminated wastes, by using    oil-degrading bacteria.
- Isolation and molecular identification of indigenous oil-degrading bacteria
   
Characteristics of oil degrading bacteria:
 - Degrading  the hydrocarbon compounds 
- Utilizing hydrocarbones as a source of carbon and energy
 - Producing carbon dioxide gas and the cell biomass during biodegradation processes
- Having environmentally safe products
 - Using as biological fertilizers to improve soil.
 
Actual Results:
  Theses bacteria  are used in three phases:
-Liquid waste treatment
 -Solid waste treatment
-Phytoremediation phase using resistant plants suitable for planting in the amended soil.
Overall achievements in one project were:
 - Recovering 727 barrels of pure oil by physical method
 - Clean-up of 894 barrels of oil contaminated liquid waste and 
  9451 cubic meters of polluted sludge and solid wastes by biological method,  - Planting of 188 tree seedlings in soil obtained from bioremediation.
