	Use of Mixture of Bacterial Strains - A mixture of bacterial strains has also been used to clean oil contaminated water reservoirs (due to oil spills from ships) and water supplies. This could be illustrated using the following example.
When 800,000 gallons of oil water was once accumulated in the bilges (botton of ship) of a ship 'Queen Mary', there was a danger that this oily water will be discharged at the harbour causing death to marine life and spoiling beaches, rendering them unsuitable for human use. When a mixture of bacterial strains was introduced in the bilges of the ship, oil was decomposed within six weeks, leaving water with innocuous chemicals, safe to be discharged at the harbour. A mixture of bacterial strains is also being used for removal of grease deposited on the inner side of tanks in a ship. The technique may also prove useful for cleaning deposits of grease in pipes and vessels of a variety of industries.
