Expression of exogenously introduced beta-galactosidase gene in a tropical, marine, oil-degrading strain of Yarrowia lipolytica NCIM 3589

摘要

We have transformed an oil-degrading, tropical, marine strain of Yarrowia lipolytica NCIM 3589, isolated from the oil drilling platform of the Bombay High region. A beta-galactosidase gene with a promoter from the yeast Saccharomyces cerevisiae has been expressed in this organism. This opens up possibilities of developing easy selection criteria for releasing this organism in the natural environments for bioremediation and oil prospecting. Since the gene is expressed in the yeast and the mycelial forms, it would be very useful for industrial fermentations using oil waste as a substrate. [References: 15]
