HISTORY OF BIOREMEDIATION:
Bioremediation has existed in the world since approximately 600 B.C. By the Romans to treat their wastewater. Although this same technology isstill used today to treat wastewater it has been expanded to treat an array of other contaminants.
In fact, bioremediation has been used commercially for almost 30 years. Thefirst commercial use of a bioremediation system was in 1972 to clean up a Sun Oil pipeline spill in Ambler, Pennsylvania. Since 1972, bioremediation has become awell-developed way of cleaning up different contaminants like cleaning up spills of gasoline, diesel, heavy metals and other easily degraded petroleum products.

The process ofbioremediation was reportedly devised by George M Robinson in the 1960's during experimentation with dirty jars and the introduction of microbes this was however not applied untilthe 1972 clean out of the fuel holding tanks on the RMS Queen Mary. Robinson then pioneered the idea of drying out bacteria cultures and using this as the basis for commercialuse this was known as the concept as 'Bug-Brew'. In the 1980’s, there was a initial promise of a technology Emphasis on bioengineering organisms for bioremediation. However,in the 1990’s there was a greater reliance on natural microorganisms and techniques to enhance their performances.
