Bacteria manage perfume oil production from grass

03.11.2008
Scientists in Italy have found bacteria in the root of a tropical grass whose oils have been used in the cosmetic and perfumery industries. These bacteria seem to promote the production of essential oils, but also they change the molecular structure of the oil, giving it different flavours and properties: termicidal, insecticidal, antimicrobial and antioxidant.

Studying the root of the tropical Vetiver grass through interdisciplinary research, the microbiologists Pietro Alifano and Luigi Del Giudice, the plant biologist Massimo Maffei and their colleagues found that Vetiver root cells produce a few oil precursors, which are then metabolised by the root bacteria to build up the complexity of the Vetiver oil. The bacteria were found in the oil-producing cells as well as in root locations that are closely associated with the essential oil.

The Vetiver grass is the only grass cultivated specifically for its root essential oil, which is made up of chemicals called sesquiterpenes. These are used in plants as pheromones and juvenile hormones. The essential oils also contain alcohols and hydrocarbons, which, together with the sesquiterpenes are primarily used in perfumery and cosmetics. The perfumery and flavouring industry could benefit from the increased variety that these bacteria provide to the smells and tastes of these oils.

The bacteria responsible for this transformation include alpha-, beta- and gamma-proteobacteria, high-G+C Gram-positive bacteria as well as microbes which belong to the Fibrobacteres / Acidobacteria group.

“This research opens new frontiers in the biotech arena of natural bioactive compounds” said Professor Alifano “Pharmaceutical, perfumery and flavouring industries may now exploit the selected microbial strains and widen their metabolic libraries”.

“The ecological role of plant-microbial associations shows another fascinating aspect” said Professor Maffei “The metabolic interplay between a plant, which offers a few simple molecules, with root bacteria, that biotransform them into an array of bioactive compounds, increases fitness and reveals new cost-efficient survival strategies”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
