Steroid Producing-Bacteria Found Useful In Medical SectorScientists at the Universidad Complutense de Madrid, Spain have discovered species of bacteria with cholesterol-busting properties. The team of Dr. Oliver Drzyzga and colleagues discovered the species by isolating the new bug, called Gordonia cholesterolivorans, from sewage sludge.

According to Dr. Drzyzga, Gordonia bacteria are capable of producing steroid compounds which could be useful in the pharmaceutical and medical sectors in the future. Despite the bacteria’s ability to breakdown cholesterol, the team pointed out that Gordonia cholesterolivorans cannot help treat high cholesterol-related conditions in humans.

From Medical News Today:

A novel species of bacteria with cholesterol-busting properties has been discovered by scientists at the Universidad Complutense de Madrid, Spain. Dr Oliver Drzyzga and colleagues isolated the new bug, called Gordonia cholesterolivorans, from sewage sludge.

A steroid found in all body tissues, cholesterol is used in the cosmetics and pharmaceutical industries as stabilizer, emollient and water-binding agent. As a consequence, steroids - including cholesterol - are a major group of contaminants in urban sewage residues.

Dr. Drzyzga and co-workers are studying the genetics of this novel bacterium to genetically modify strains that might also be used to synthesize new and industrially useful breakdown products of cholesterol.

New steroid compounds made by these bacteria may find applications in the pharmaceutical and medical sectors in the future, but as some Gordonia species are pathogenic to humans it is unlikely that they could be used directly to treat high cholesterol-related conditions in humans”, said Dr Drzyzga.

Gordonia bacteria have only been classed as a separate group of bacteria since 1997 but they have already proved useful as they are able to degrade a wide range of environmental pollutants including phthalates (used in plastics), rubber and hazardous compounds such as the explosive hexogen. Gordonia’s ability to break down cholesterol means that it could be used to clean up contamination.
