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.
对原油作为能源和工业主要原材料的需求增加，导致了原油生产、运输和精炼的增加，进而造成了严重的环境污染。在本研究中，从市售的当地发酵饮料“佐博”（由芙蓉花制成）中分离出的酿酒酵母，在需氧条件下进行了为期28天的测试，以确定其降解原油的潜力。使用失重法和28天后残留原油的气相色谱-质谱联用仪（GC/MS）测定了石油生物降解的百分比。在28天结束时，记录到原油降解率为49.29%。结果表明酿酒酵母在石油污染场地生物修复方面具有潜力。
