Biodegradation of crude oil by Saccharomyces cerevisiae isolated from fermented zobo (locally fermented beverage in Nigeria)

The increase in demand for crude oil as a source of energy and as a primary raw material for industries has resulted in an increase in its production, transportation and refining, which in turn has resulted in gross pollution of the environment. In this study, Saccharomyces cerevisiae isolated from...

Description
Summary:The increase in demand for crude oil as a source of energy and as a primary raw material for industries has resulted in an increase in its production, transportation and refining, which in turn has resulted in gross pollution of the environment. In this study, Saccharomyces cerevisiae isolated from a commercially prepared local fermented beverage 'zobo' (prepared from Hibiscus flower) was tested to determine its potential to degrade crude oil for a period of 28 days under aerobic condition. The percentage of oil biodegradation was determined using weight loss method and gas chromatography mass spectroscopy (GC/MS) of the residual crude oil after 28 days. At the end of 28 days 49.29% crude oil degradation was recorded. The result suggests the potential of Saccharomyces cerevisiae for bioremediation of oil polluted sites.
